I noticed some GodCity Instruments builds were using discrete opamps, 2520 I believe. I know they can have higher headroom, lower noise, and run at a higher voltage. This can be dependent on the circuit, but are they worth the hassle and have any of you used any in builds? Just curious.

I know let in terms of transformer use for this pedal. Unfortunately Mouser is out of TY-141P but I have some 42TM018-RC transformers which are also 10K/10K. However it's resistance is 550/500 (primary/secondary) compared to the recommended which is 820/1070(P/S). Two questions does the...

Been getting a lot of SMD pedals/amps needing repair, so my question is does anyone have any good methods of checking/testing components? Currently I am using a multimeter and I made a logic probe for digital sections. I just feel like there has to be a better way. Appreciate the help.

I got a free broken Way Huge Russian Pickle I figured I would ask before I start reinventing the wheel. Is anyone familiar or could point me in the direction of the power circuit used in Dunlop/Way Huge pedals? What I have found is that the yellow trace connects to ground the only component that...

With Dunwich calling it quits this pedal is already going up in price. It seems to based on a Green Matamp with a boost of some sort. Apparently another company is taking over the designs but it is already getting crazy over some of these pedals.

Was cruising on my lunch break and found this cool eurorack someone converted into a pedal. https://github.com/pichenettes/eurorack/tree/master/clouds https://github.com/pichenettes/eurorack/tree/master/clouds/hardware_design/pcb...

Pretty simple replace the 100nF capacitor with something bigger to change the corner frequency. I put two others on a switch stock 100 nf, 220 nf for beefy guitar and 1 uf for crushing bass. Typical tubescreamer mod but really makes it a whole new beast. This was about the easiest location for a...

A PCB or EPROM patch for one of those weird splicer like pedals like the Grazer or Count to Five. Weird pedals but I have uses for it live I don't want to talk to people so weird noises.

Anyone got a line on FV-1 chips? Seems like my usual places in NA are sold out. Any suggestions?

Steep ask because I think bass stuff doesn't get much love, but I would love a Rusty box, I have a layout for an etched board but I just don`t do much time for etching anymore. Also got any of them blend boards?

I am mainly posting this because there seems to be some Big Muff love here, but someone posted a veroboard layout. This is the Muff used in some older metal albums, but seems like a cute idea.

Wanting to adjust the EQ of the Small Fry for bass just not familiar with the EQ circuit so I am not sure what to search. If anyone know what to call this or is familiar with how the the bass, mids, and treble control works it would save me a lot of random breadboarding. Schematic here...

Have a bunch of Ge PNP transistors sitting around looking for some recommendations for builds. I know there is the Arbiter Fuzz Face anything else?

I know this exists else where but a centralized non-SMD version of this would be great all FV-1 products in one go. http://www.hexeguitar.com/diy/utility/fv1progsel

A lot of musicians I have met recommended the Cali 76 compressor. Normally not into compressor but have seen it enough wonder.

I see a lot of people ask for a Sunn beta preamp pcb. I have a etchable layout if people are super interested but a smaller PCB with the bipolar power portion would be nice.

Westwood or Sherwood on the left and Coda Sunn Model T preamp on the right. I used gel food coloring to give an anodized effect I think it turned out well. Sherwood/Weswood sounds great on bass.

Massive delay/reverb like Disaster Transport Sr. would be great, I remember seeing pictures of the PCB and it seems do able by DIY. Could be neat to have accessible to the community.
