Thanks Barry. Trying the 6.8k route to tame it for me.

Missed the conversation and that you took time to reply. Sorry.

Playing a Fender Jazz Bass in the Hi-Z of an Apollo Interface into an Ampeg SVT simulation.
Tried It into a TC 500W head hooked to a 4×12 Hartke 10″ cab.

When engaged, the signal jumps 21+ dB at lowest potentiometer settings. So it is driving whatever comes after it “heavily”. It’s not intended like this, or is it? You cannot play “clean” and then engage. It kills you instantly ^^

I wired the potentiometers temporarily until this pcb works haha. Lug1 of the Poti is connected to the square connector on the PCB.

Just measured (9V power supply):

Q1:

• D 5.87
• S 1.3
• G 0

  Q2:

• D 5.81
• S 1.56
• G 0

  Q3:

• D 5.67
• S 1.4
• G 0

Hello. Franz here. First post!

Bought the Bass OD from musikding.de

I cannot get it sounding right at all. Tried biasing for the recommended voltage, tried Passive & Active PUs, In front of an Amp, into a DI etc.

It is way too loud. Volume control unusable. It is like shooting at my Audio Interface and breaking the preamp. Gain does not start at slight, even at 0, you can hear it cut through (some crosstalk) with full drive power. Dealing in more sounds like 100 broken amps in a row. That’s nowhere near usable. Checked the wiring, the components again and again. No improvement. Any idea how to tame the beast or what could be wrong?

(btw. there is a mistake in the manual, section “populated board”: R11 shows as 33K Ohm, but in the schematics and parts table it is 1K Ohm. So I soldered it in wrong on my foto, but I tried also with R11 at 1K Ohm. Does not work either.
