I've got a Magnetron that I put together a while ago that didn't work until recently. I don't know if this is part of the circuit but with the Gain trimpot all the way down I'm above unity gain a decent amount and with it above a 1/4 turn it gets into boosted level territory.

The BOM for the MicroBlend Crossfader is incorrect and needs to be updated with the correct values and case codes.

This is quite possibly the best wah I have ever heard. With the buffer on it is crystal clear and very expressive, and with the buffer off it is very vintage sounding, not quite like a McCoy but very close. My problems with the other wahs are the usual: The Bonamassa is too dark, the Ernie...

I have dived into a rabbit hole concerning wahs. I have an Ernie Ball wah that sounds a bit better than stock after some mods, I did a couple mods to my lead guitarist's Joe Bonamassa wah, and my vocalist has a GCB-95 from 1992 that he wants me to spruce up. I decided to get a Sham Wah board...

Nice. Name your price and which payment processers you take, and I'll send the money over.

I have been on a kick recently to make my Ernie Ball Wah work better with bass, including downtunings. Here is what I have compiled so far. I made quite a few changes. The rotary, pots, and toggle are mounted on the left wall of the enclosure. You will have to remove the back plate that...

Radical, you're the man Stickman. Any chance I can commission an inductor from you? Several people that you gave them to say they are excellent.

Exactly, keep the drive tight and keep the bottem end clear.

I would actually setup the crossover to control where the drive comes in on the frequency band. One of my favorite bass drives has a crossover that shifts from 50Hz to 1kHz. Everything below that split is clean and everything above is overdriven. If you want to take it a step further you can...

My first question, does this have a clean blend or a controllable crossover? My second is have you looked at Aion's schematic for the Empyrean bass drive from Aion? It is a clone of the Darkglass Alpha|Omicron/Omega drive. While it is a distortion it uses opamps to produce the drive. You can...

I took the time trace my Ernie Ball Wah, so here it is for anyone who wants to mod it. As a warning I may have mixed up the 1K resistor with one of the 10K resistors when I was pulling components. EDIT1: R11 is 1K and R30 is 10K. EDIT2: Fixed the schematic. EDIT3: Better schematic.

@Stickman393 Any recommendations for an inductor that will fit? I am using this on bass so I am modding it in general to bring the range down so that resistor pull is a good starting point.

Any chance you would want to look at an Ernie Ball Wah? The furthest I've gotten with mine is that it uses a J201 input buffer and three 2N5089 NPN in the signal. The inductor looks to be sealed in a can so I have no idea what style it is, however it says 420 on the top so I'm assuming that's...

@maertz13 While that is true, Walrus Audio changed the blend portion just enough I would have to offboard wire it. They use B10k vs Boss's C250k and I would need to jumper 2 resistors, I may as well use the Cepheid board I bought. I appreciate the consideration.

Any plans to sell some boards? I'd be done to buy one. Does the pad allow you to plug into a power amp directly?

@tegendemuur Exactly as Alan W said, measure the pertinent parts and go shopping, from experience a lot of equipment tend to come out to FMC specs for some reason. You can use a ruler instead of calipers if you have good eye and steady hand.

That was a port over from the CH-1, I could replace it with an LM741 or a TL071. I could also build another de-emphasis stage and take my dry out from just before C6 instead of just after the input buffer.

Bump. Can anyone help verify please?

@tegendemuur If you can get me a better picture of your roller wheel assembly, I can tell you what will be compatible. I had to do this for an SWR 4x10 bass cab a while back.
