Boss VB-2 Vibrato Schematic

[sevenisthenumber]

I need to replace the rate knob on my VB-2 and cant find the schematic. The pot doesn't physically say anything on it?

[SonicVI]

Is it in a state that it can still be measured with a DMM?

[scotsman]

It's a c250k

[sevenisthenumber]

It wont measure....


What does the "c" mean on C250k

[scotsman]

Reverse audio taper.  Smallbear has them in 16 and 9mm but they don't have the same shaft.  Meaning they aren't knurled - they are smooth.
It'll knock down the value of the pedal.  You are best off finding another boss pedal that uses the same value pot like like the BF-2

Just found the schem on my computer...

If you call Boss Customer Service they'll send you a new one. Just tell them which part for which product. Worked for me.

What problem are you having? If its not modulating you may need to tweak the LFO.

the rate doesnt work until its almost all the way up and then its insane.
