Re: How to Mod Rat distortion pot to be less sensitive in super low range

I can confirm that a 10k pot does the trick, I left the old 100k pot in and just soldered the 10k one across the outside lugs. I love the Rat as a low gain pedal and this definitely achieves that. Don't mind the very awkward placement of the knob, I'll get around to drilling it in later haha

Re: Alternative RAT 2 potentiometers

It isn't pretty at all but it works! 10k log pot soldered across the existing distortion pot turns the Rat into a low gain overdrive. With the new distortion knob at maximum, the clipping is equivalent to the original knob at around 30% up. Which allows for really fine control over the very low valu...

Re: Alternative RAT 2 potentiometers

Yeah unfortunately I'm looking to keep the taper logarithmic as I'd like to have more precision in the lower gain range. I played around with a few pots and it seems like 10k works best for me. I think I'm just gonna wire in a separate pot on a switch and mount it somewhere else so I have the option...

Re: Alternative RAT 2 potentiometers

Damn, yeah I've spent all day looking but no luck. Such a strange design but I don't think anything else will fit nicely

Alternative RAT 2 potentiometers

Hey,
Does anyone know where to find potentiometers to fit a Rat? My Rat uses these:

https://stompboxparts.com/potentiometer ... meter-rat/

but I'd like to swap one of them out for a 50k pot.
Can't seem to find one that looks similar on any of the websites I'm familiar with.
Thanks!

Inverting Op Amp Low Output (What am I missing?)

Hi, I'm trying to make an inverting op amp buffer as I want to flip the phase and buffer the signal. I've attached a photo of my breadboard and the circuit I'm trying to follow. When I connect it all up, the output is super low, -30dB or so from where I started, and it looks like my signal is being ...
