45th Anniversary of guitar building!
Joined Nov 4, 2003 Messages 7,550 Reaction score 13,716 Location Pittsboro NC Hello all, I've worked on the acoustics of my control room on/off for 4 years now, and have finally arrived at the "this is gonna work!" stage. I am blessed in having an old friend to advise me (periodically) who has made a big name for himself as a studio designer...Wes Lachot. https://www.weslachot.com Wes got me off to a great start and I've been tweaking sporadically ever since. It's all been via DIY bass traps (the biggest of which are two measuring 6' x 3' x 7') and broadband absorbers, with a little diffusion thrown in too (in truth I'm still playing with diffusion a little). The dimensions, makeup, and placement of these required much experimentation/dead-ends. Thank goodness for R.E.W. (BTW the Dayton mic for that purpose works very well). There has been no use of "studio foam" (except for what the monitors sit on, and removable panels for the screen and mixing console, these are only used when mixing and then only on occasion). I've learned that foam is of little/no use (with respect for users of foam). It's really vital that I get my control room "right"...if only for business reasons. You see, part of the process of exploration at the beginning of ordering a TCM guitar involves the potential client sending me 5 songs that he/she feels hint at important attributes of the "sound to be built". Prior to sending these, a potential client and I have at least one longish, very fun conversation about the person, his/her music, guitars, and sound; we are talking about "building a sound" and I do not feel comfortable building a guitar for someone until I *feel* that my "musical imagination" is in tune with their's. It often requires more than 5 songs but when it "clicks" I can begin to choose materials and get to work. This took many years to fine-tune. That's why it is vital that my control room sound as accurate as I can make it; I need to be able to HEAR! The control room is every bit as important a tool to me as a guitar builder/guitar designer as any of my woodworking machines; I literally couldn't/wouldnt build TCM guitars without the control room. I use it for listening to sound samples, on-going education about sound, and for proprietary methods of testing the resonant characteristics of woods, guitar parts, guitar chassis', and chambers. Without being able to do these things I'd be building-by-numbers, and IME that's boring/no fun. Of course I also use my control room and modest live room for recording music and I'm working on a record; when that's done I'll assemble the band and haul it around the clubs (Yay! Clubs are about to re-open here!). One thing that I have learned over the course of many control rooms is that it is a waste of $$ to buy into expensive gear until you can accurately hear what is going on. I used to rebel against that truth, because it was going to be a lot of work to get a room sounding good, new gear is much more fun, messing with compacted fiberglass and Rockwool is no fun, you gotta test-make changes-test again (repeat) and again new gear is FUN. And so, I used the same set of control room monitors since I bought new in 1998. These were the original, MK1, Mackie HR 824's. They are flawed (!)...they have their fans and detractors...but they never blew up, got carried all over the place, were situated in a total of 5 controls rooms over the years, and I got to know them pretty well...and that's important...if you KNOW your speakers you are well advised to carefully consider changing to something else. To this day, I think that a pristine pair of the original MK1 Hr 824's are an excellent choice in the $500-and-under range, for sure. The Neumann KH 310 monitors. As my control room became more-and-more accurate, the Hr 824's sounded better-and-better; but at a certain point I just had to upgrade my monitors and doing so, while not cheap, was necessary (Im never getting rid of the 824's BTW, they are doing excellent duty as echo chamber speakers, one of the few things I have in common gear-wise with Bob Clearmountain). And so, I called Wes Lachot for advice. I was expecting to swing for a pair of ATC SCM25A's. Wes has spec'd those for many of his world-class studio builds. In my mind, I was calling him for confirmation of this presumption. "The ATC25's are really great speakers" said he, " but you ought to check out the Neumann KH310's. We are getting fantastic results with them, I've just ordered a pair for my own use, and they are about 1/2 the price of the ATC's and you really aren't sacrificing anything. They would sound fantastic in your room". I'm like really? Competitive with the ATC 25's? Answer: "absolutely, and especially for your room". Oddly, I hadn't looked at them much. But when I did, they checked all the boxes as follows: - 3 way design -Sealed box - tons of clean power - loads of great reviews (I always take reviews with a grain of salt though) And so, I was able to swing a deal and got a pair. They sound really, REALLY good man. My main onus regarding voicing the control room was to make the mix position (8' x 4') in my room sound right, and I can scoot to-and-fro, front-to-back with these Neumanns and remain in a luscious, deep, wide sound field. In the money spot...an area measuring around 4' x 4'...I cannot tell you how joyous it sounds. Really tight and punchy "PA bass"...hearing things on my ref mixes Ive never heard before...pointing out massive flaws on earlier mixes....more volume horsepower, crystal-clean than I'll ever need...WIDE stereo sound field...etc etc. Whoa.....all that work on the control room paying off! One example being that you can sit in the money spot and slowly pan something left-to-right and clearly place that instrument. Take a hi-hat for example; you can pan a hi-hat slowly and hear every little subdivision of placement, instead of a left-center-right placement with a blurry transition between those three positions. You can walk that hi-hat right across the stereo sound stage. Of course, the work on the room makes that possible, but the Hr 824's...no comparison. The 310's are AWESOME for tracking guitars. They sound fabulous at the rather high volumes I use when monitoring the amps downstairs. Inspirational. They get VERY loud without any strain. You immediately hear any minute change of mic position. Plenty of running up-down the stairs is gonna convince me to buy a couple of robotic mic stands, I'll bet. Mix-wise, dialing-in the various compressors, EQ's, delays, and reverb is a whole new game. You can hear everything, with ease. Moving things front-to-back via ambience is readily heard; any frequencies that step on each other are pretty obvious too. It's actually created more work, since some of my go-to, this-and-that is revealed to be not as good as can be. But tracking good sounds is easier than ever, because you HEAR. I would have thrown plenty of $$$ away to no good use if I hadn't gotten my room right prior to buying the 310's. Ive worked in good control rooms in the past and so had an idea of what worked. Now...finally...I am pleased with my mix position. Buying the 310's would have been a giant waste of money sans the work on the room. They would have been inaccurate in a different way, is all. A view from the money-spot. To answer a question in advance, the little desk is the last UK Midas design (sadly!), the VF24. Highly recommended, the EQ is very usable as are the mic amps, and the 2-bus saturates nicely. Its a total underdog. I'll be hanging on to the Midas until I find the right deal on an Amek Angela (blue face). Tons of routing. Time for me to get top-class converters though! Via the patch bays I can use all of my 42 spaces of analog outboard as I wish. ZXcu0kX.jpg Serious Poo

Agree 100% on learning about and investing in room treatment before spending big money on monitors and such. Also, love using KH310's - they're super transparent monitors to my ears. I just got a matching KH750 sub for mine and will likely hook it up over the holiday weekend. marmalade cream

I am actually about to start building out a new basement control room in a new house. I've been forced to work on headphones for the last six weeks while I get a bunch of work off my plate so I can start the room, and it makes me miss my monitors (Focal CMS65's) a lot! Glad the Neumann's are working well for you! 56Tweed

Thanks for your question! As luck would have it, twin neighboring closets in an appropriate area right behind mix were available to repurpose for bass trapping, and the wall behind mix position in my room needs to be heavily absorbent + the right amount of diffusion. And so the closets were given-up for trapping and it made a great and good difference. Regarding the diffusion in the room, it varies according to what part of the control room we are talking about; it could be wooden slats, it could polycylindricals, it could be multi-faceted thermo-formed plastic diffusor products stuffed tightly with rock wool. Down in the live room the diffusion is a mish-mash of random objects in the room (including drums, amps, PA gear, etc etc a room-length bookcase along one long wall (with books), and polycylindricals. Here's a pic of the very humble live room in it's original configuration/pre poly cylindrical diffusors and plenty more gear. Behind the camera is a seating area with TV, tables, couch, chairs etc. Whats in the pic is 50% of the room. I'll probably rearrange everything. You know how that goes! dWbcdd5.jpg Last edited: May 27, 2021 Blix

It's part of an interview process that's taken a number of years to "get down" but it's always improving. Basically, I need as much info regarding the sound to be built as I can get, without having to listen to 40 songs. 5 songs at first, with a possible re-direct to 5 more with additional instruction is working here. The main-aim here is to identify what acoustic guitar needs to be made; the voicings of the microphones (pickups) follows closely behind. Suppose that you interested in ordering a TCM Carolina Custom from me. In order to be sure that I could deliver what you seek, I'd have to be sure that one of the four available acoustic voicings for that model would work (they are all solid bodies made from the same species of woods, same scale length, etc etc). If I can't build the right acoustic guitar I cannot accept your order, because I wouldn't be able to build the sound. It's not a simple matter of basic specs, basic woods, basic pickups, basic hardware. It is unfortunately and inconveniently more complex. But in the end it is fun and really rewarding. While I won't go into the finite process at length here, but broadly speaking I'd be asking for: -At least 3 out of the 5 songs be clear recordings made in the modern era - The other two songs can be things that move you, but which also have attributes about the guitar sound to be built What I'm primarily listening for is any commonalities regarding four frequency ranges plus a commonality regarding the rise-time. Many of our favorite classic recordings aren't as useful to me as I wish they were; with many of these, there are too many recording issues to "hear-thru", even for me. A typical example of a fantastic classic recording that's of limited use to me is the ABB Live At The Fillmore. The guitar signals have been so drastically altered from that which we would have heard sitting 10' in front of the Marshall amps. Another classic example being VH1. It's extraordinary guitar playing, with a tone that was changed from reality into what would sit with the production. If we were sitting 10' in front of EVH's amp during those sessions, it would sound markedly different than the record. Listening to recordings as a cue as to how the guitar actually responded is a tricky bit of business, but it is useful IF a good knowledge of the recording process' effect upon sound is in place. It's not perfect, but is extremely useful. Often, part of the interview process involves me suggesting a new way to listen, so as to provide me with samples that I can use. But every sample submitted IS of use; getting to know a person's music is vital! Last edited: May 27, 2021 spence

I’m interested in the bass traps too. What are you filling that space with, and how are supporting it? I’m about to build a bass trap wall about 2ft deep, and I’m looking for ideas on how to support the insulation that will fill the space. drfrankencopter

The way that I did it was to build two false "doors" that fit tightly into the door frame. These are loaded with 6" Rockwool with tapestry facing the room and fuzzy cottony stuff on the inside holding the Rock wool in place. Then, the open closet behind was simply filled up with Rockwool, and fiberglass scraps too. If you have a 2" deep wall to fill, you could do what a friend did, and simply hang 24" wide fiberglass sideways from the ceiling to the floor, in effect getting a solid wall of fiberglass 2' deep. He did a nice job of stretched fabric on the outside. Terry McInturff

Yes, Ive been meaning to ask Wes about that. However, the mix position sounds really good as-is, so Im not sure what I could achieve but I'll look into it, many thanks! marmalade cream

Ah clever! Yes the hanging wall is what I was planning on doing. I can actually mount a sheet of 1/4” pegboard from the joists, and attach 4” of 703 on either side of that. Then a 2 or 4” panel of 703 with fabric stretched over it in front of the hangers to make the “wall.” That would give me 12” of trapping with 12” of air gap behind. I haven’t decided how much I’m going to fill the whole wall yet. drfrankencopter

For me, the big takeaways were: 1. Improved imaging and ‘phantom center’ 2. Fixed a bit of a bass hole I had around 120Hz 3. My B monitors now sound almost the same as my A monitors. The positioning is less of a factor in their sound now 4. “house curve”...I have a little bass tilt in my house curve. My mixes were ending up a bit bass heavy because of taste; this let me get the bass lean I like without making the mixes themselves overly bassy cheers! Terry McInturff

What size is the sweet spot for that correction? Its a type of DSP EQ am I correct? om42

I think that the Bruce Springsteen record "Nebraska " was recorded using a Tascam 4 track cassette recorder. It's all about the songwriting and performance, all of the gear is in 22nd place by comparison!!! Many thanks for your kind words drfrankencopter

The size of the sweet spot is kind of a function of the distance of the monitors. The closer the monitors, the smaller the sweet spot, but probably the more accurate you can get with the correction. I use Dirac Live, and when you start the calibration you can choose what the listening position looks like. Basically they give you options that look like 'chair', 'loveseat', or 'sofa'. If you go for sofa you get the biggest sweet spot. I think that's what I went for...or I might have gone with loveseat for the nearfields, and sofa for the mains. The Dirac Live setup I have is running on miniDsp hardware with balanced I/O. I didn't want to have to deal with the room correction being a plugin, and wanted a low latency solution. It's DSP EQ, yes, but they use some clever filters that improve the impulse response as well as the frequency response. (Their hype about it can be read here: https://live.dirac.com/technical-information/) I picked up the version with bass management, so if I ever decide to add subwoofers they'll be easy(ish) to integrate. I had also demo'd Sonarworks, and while I like the UI of sonarworks better than Dirac, the sonic results with Dirac were better. That said, Sonarworks does work as advertised.
