DoesQuote from: somnif on October 03, 2018, 01:24:43 AMI guess the Isley Brothers were time travelers. "That Lady" (the funky version), was recorded in 1973. The Roland AP-7 came out in 1975.
note: The actual effect used in the recordings are hhypothesized to be a Roland AP-7 "Jet Phaser"...
As with pretty much every Phasey-sounding tone that nobody can figure out, it's almost always a Maestro PS-1a. That should be the first guess every time, but it's always the last thing considered. Whenever in doubt, always guess the Maestro PS-1a.

For "Whose That Lady" in particular, you'd want the Lectrix FX "Countdown Phaser". Its based on the A/DA Final Phase, a CMOS phaser with built in overdrive effect.
note: The actual effect used in the recordings are hhypothesized to be a Roland AP-7 "Jet Phaser" and a Roland Bee Baa fuzz, injected directly into the recording board. Neither of which has much shelf space in the DIY world.

With the Brassmaster, anyway, the problem lies in the PCB ground trace. After it snakes itself all over the board, it comes back out at a pad meant to connect to one of the switches,but by the time it gets there, it has picked up a slight bit of voltage and no longer makes a good ground for that switch. It is not at all clear to me from looking at that board layout or the schematic where that tiny DC shift comes from,but the solution is to cut the ground trace at a certain spot and run a new ground wire to that part of the board.
Edit: Now that I've though a bit more, it might just be that a noise-generating component (the spike-throwing switch) is at the wrong end of the ground bus, which pollutes the ground current of the other parts of the circuit....
There may be something similar going on with the Mutron boards. Check to see if the board itself is being used to ground external components, and trying running dedicated ground wires instead

But the selector switch, forQuote from: jduma on September 25, 2018, 12:20:47 AMIf you end up buying a Brassmaster from GGG and have problem with it popping, let me know. There is a mysterious problem with that layout from R.G. Good news is that the solution is fairly simple.
Yep been busy and wanting a Brass Master for practice and was thinking of taking the easy way out.
