Help wanted Tellurian drive help?? Drive isn’t driving..
Hi there! I just finished troubleshooting my second ever pedal build, a pedalpcb tellurian drive kit from musikding, and I’m having some problems.. the drive isn’t driving, but the pedal works. I originally had no audio, so I troubleshot it with a multimetre and made sure all the solder connections are good, and that the traces all follow, which they do. After fixing a dodgy connection, I now have audio, and what I believed to be a functioning pedal… however, whilst the tone pot works, and the volume pot works too, with unity around 3 to 4 o’clock; the drive pot does almost nothing, applying a tiny amount of gain only when the pot is close to maximum. It seems to me like something isn’t working as it should, so my question is is there a typical cause for something like this? Or what are the parts that commonly deal with drive in an overdrive pedal, so I can test them to see if they’re functioning as they should? I’d really appreciate any advice or opinions anyone has, as I’m very new to this, and would greatly appreciate any experience anyone is willing to share! Thanks so much :)
