My acoustic preamp build. Used a BB size box so I could add some extras. Used the buffer/inverter board for balanced output direct to PA. Found the overall volume boost not enough so I added a Muffin Crumb gain stage to the input with a trimmer to help out my low output pickups. Probably...

I built a Capsize preamp to experiment using with my acoustic. It has a Fishman magnetic sound hole pickup, not piezo. It is a pretty low output pickup so I was looking for something to clean boost and add a bit of tone shaping. I also added a buffer/inverter for an XLR balanced output. It works...

This thing RIPS !! Just have to decide how to label the knobs.

I have built a Stagecoach (Barber BUSS) and I really like it except even with the tone knob all the way up, it doesn’t have much treble and no presence at all. I’m wondering if this is normal for this circuit. And, what is the deal with C6? Seems like it would be dumping treble to ground before...

No build documents available yet so I’m wondering if this will be capable of using the inverted and non-inverted outputs simultaneously for use as an active direct box. ?? Doesn’t seem like there are quite enough components on the board to do this the way I am familiar with...

I have built the Cobbler preamp and use it as a clean pedal platform along with the Unicab to run direct to FOH and it works great. I recently bought the Bobby preamp board planning to build a Marshall flavor to use as well. After reading some reviews of the Sheriff that it is derived from, I...

I have built this amp sim box out of a Cobbler, Unicab, and an AMZ opamp board for an active DI output. https://forum.pedalpcb.com/threads/amp-cab-di-experiment.16398/ I want to run it from a spare 18v output on my power supply instead of a separate 9v power supply for better headroom on the...

This is my Amp/Cab/DI experiment. Cobbler preamp into the Unicab cab sim, then an active DI circuit on the AMZ opamp board. There is also a 1/4” output before the DI I can use if needed. I have tested it into a USB interface and monitored through a class D amp and full range speakers. It is...

I had this leftover back box for an Aiphone door station at work and just had to build a multi-fix out of it. These 3 work great together. I just need to find a plate to cover the bottom.

First post here but I’m not new to pedal building. Amongst my many builds I have built a Van Pelt drive and Magnetron delay and just discovered that if I connect the Magnetron into the Van Pelt, the output volume cuts down to almost nothing. Both pedals work fine in all other contexts and it...
