The Bass OverThruster is essentially what I built to sound like the Mike Scheidt Yob pedal in a much cleaner package. Don’t dismiss this as just a bass pedal, it can do Doom guitar as well, try it with low A tuning. This one can really melt your face.

They were for Muse (Hysteria) and Y.O.B (Heavy Doom) sounds. They might not be a good fit but I can pass along the formulas if you’re interested.

I  recommend using some sockets. Your rig will determine what sounds good. I also added an option to switch to 3 BAT41’s for asynchronous clipping on that same pedal but never liked it in the mix.

I used a set of BAT41’s in one of Barry’s older Blues Buster boards which is very similar to the new NT 60’s Overdrive. I did an extensive diode shootout before deciding the BAT41’s sounded better with my rig that the usual 1N914’s or 1N4148″s. Thanks for mentioning those.

As I mentioned, the forward voltage is what effects the signal. An average red LED has a forward voltage around 1.6 to 2.0 volts so any signal above the 1.6 to 2.0 volts will be clipped. The 1N4148 diodes called for D3-D6 have a Vf around 1V. They will…Read more

The S4/S5/S6 pads are connections that should go to the foot switch to activate the LED. Without a switch or jumper there the LED will not illuminate. If you want the LED to be on whenever the board is connected to power, a jumper between S4 and S5 should do the trick.

For that you should start around mid-sweep on the trimmer and make very small adjustments to find that spot.

Another basic question is, are you using a known good power supply?

The troubleshooting could be getting more technical…Read more

I think it’s one of the best tools to isolate issues. By being able to verify a good audio signal at the input to the board you have a quick way to know which direction to go with testing (usually). It can also help locate problems on the board by following the audio path on…Read more

You could de-solder the leg of R9 that connects to R22 and lift it from the delay board. ( sorry I don’t have a board to verify which leg that is ) Then connect  a wire from…Read more

If it is mounted reversed in an audio path, it will block your signal.  If you don’t have a non-polarized cap handy to replace it, just flip that one around and it should work.

Keep in mind you can let the smoke out if you reverse the v…Read more

Looks like you used a a tantalum cap for C1 on the buff n blend board. If you did, be sure the polarity is correct. Positive should go toward input or R1.

Try something different. Consider using some sockets and populating C3. Start with a 22p and work up. If the extra cap doesn’t fix anything just take it out, no harm no foul.
