Any good, rackmount, DIY monitor controller kits out there?

...or some mods that I can do to make my Mackie Big Knob sound better / become rack mounted.

I was just looking to see if there was a DIY option out there. Figured it would be a pretty simple build for a beginner, but I think the Mammoth might be the one.

actually, steiger uses the vishay on the 528's, he matches those painstakingly, and there are a whole lot of them to instal on what ever switch you get, J, you should ask how many attenuation steps, and the matching tolerance R to L on that mammoth? if you don't, i will i guess.

I like having a nice tactile volume knob, similar to my big knob. The knob on my console is small and just not really what I want to use. I'd rather have something rackmout to free some desk space too.

About all you need is an attenuator and a recovery amp. I built my own and used them for years. I used a greyhill input selector rotary switch, a 1~5 k dual audio conductive plastic pot (matching elements first) and a recovery opamp, I like the LME40713 CFA with a servo.

Set that up and you get very low THD+noise, very low noise specs and zero degrees of phase shift. Bandwidth is around 30 mhz and slew rate is 2kV/us. There is nothing available in traditional voltage feedback that approach the sonic purity of that design. Everything else is a filter.

I ended up grabbing a Mammoth Cave one. Thanks though.

I am almost finished with building the Sound Skulptor MC624. I am very impressed with the feature set and the layout.

Hi Blue, I think it's a very nice unit. I haven't implemented it into my setup yet as I'm transitioning locations. I ran a CD player through the RCA inputs just to check out functions and feel it's almost worth the cost just for the headphone amp. The fact that you can use it with a TV remote is pretty cool, but that seems a little bit complicated to me.
I've purchased a whole lot of items from Jean-Pierre over the years and it used to be a little bit expensive because the Euro/dollar ratio was in favor of Euro, but that has changed quite a bit this year, so it's a better time to buy items from the Eurozone. The last two purchases I made from Sound Skulptor were shipped via DHL and literally got to me in two days. And I didn't pay extra for quick shipping. Well, DHL does have a Hub two towns over from me.
Oh, and Blue, it's hard to tell from the website, but the front panel of the MC624 is a really nice deep Blue color.

keymod hey bud, can you tell me what opamps they are providing with that kit? It looks like a very powerful tool, much curious 8)

thanx

Tony, my unit is at my ex's house so it might be a little while. You might find that info on the website.
