Old thread but I want to breadboard this at the least. I searched for a replacement for the P28 transistor, but got AC125 and AC128...

Any PNP Ge should work. Select R24 as req'd. Mind the pinout. GT309 has the emitter on the middle pin.

Looks good, but I do not recommend 2N3904 & 2N3906. This circuit needs high gain transistors. NPN: 2N5210, 2N5088, 2N5089, BC549C...

No. That LED is the bypass LED. On this Moonshot build, there are two locations to place the bypass LED. The other one is at the bottom...

It wouldn’t surprise me one bit if Marshall got the idea to use parallel channels in a pedal from someone else. 😂😂😂 It’s a decent...

We'd need to tweak a few caps for bass.

NOT VERIFIED Component Side: Solder Side:

C5 only connects to GND & R8. No connection to U1-6. One last iteration: C13 added. The AGC loop had a bit of ringing and overshoot...

I'm starting to work on a layout. Does C5 connect to pin 6 of U1? As is, it does not, but better safe than sorry

Any time you build a JFET circuit without selecting JFETs and/or checking the bias, you are rolling the dice. My mods are not more...

Air circuits!

I should have mentioned, the characteristics of the pedal will also change with biasing. I like the biasing 10K trimpot sub for the...

Upon @HamishR 's enthusiastic suggestion (thanks, bud!), I had a go at this circuit. The breadboarding was super dumb, but I struggled...

I don't know, maybe. Haven't tried it. The thing I like about this circuit is its fast attack. Increasing R21 reduces the...

The peak detection circuit and decay have already been discussed. But would a variable resistor in place of R9 allow for some useful...
