There are a lot of considerations when routing circuit boards and often we have to make compromises. Keep input and output circuits...

In some cases you can expect a different sounding circuit, sometimes not. And sometimes you'll need to change a value of the...

I think 2n5457 will need significant adjustment of the drain resistors to bias correctly, and will be lower gain. The sag knob may not...

Ah, and my J201s are a mix between Mouser (ON Semi), GuitarPCB (Fairchild) and Pedal Hacker (Fairchild). The ones that brought the drain...

I did check the drain voltages, they're somewhere between 4V and 4.5V on both. I tend to run my amp fairly hot, though, so maybe the...

Question since you find the sag control to be subtle. (I find it to increase the distortion quite a bit). Where did you source your...

R14 would be a good candidate. Something like: Replace R14 with 10k trimpot Trimpot wiper goes to 10n cap 10n cap goes to ground...

A nice little circuit that does chorusy/vibey/somewhere in between modulation. I really love the light blue with the cream muff knobs...

boss oc-2! Pedalpcb has a board for it now.

After reading thru various threads on various forums I come to the conclusion that everyone is in panic mode and for once I am not...

Tonebenders are okay with buffers, so the FF is the only one that would be a problem, but you could put an AMZ pickup simulator circuit...

This split n blend circuit sends the input to two buffers. One buffer goes to the dry side of the mix knob, and one goes to the send...

Right on. I should have mentioned mine is the half stack (1x12 cab), I’ve not tried the combo. It’s had some issues (failed PT, vol knob...

My typical setup is a tele into an epiphone valve jr. the amp has some circuit mods including a tone knob (like tweed Princeton tone...

My ROG Supreaux Deux sounds amazing at 18V. I play mostly clean, so the increased headroom is great for dialing in just the right amount...
