Infinidrive Gain sweep

[moonlightpedalbuilds]

My gain knob on my Infinidrive is not working right. Gain from zero to about 20% turn(9 o’clock) it jumps to about 90%. From 9 o’clock to full no difference on the sweep. Any ideas? Is the 500k pot correct for this circuit?

Sounds like a reverse log pot. Are you using A500K, B500K or a C500K pot?

Linear B500k

Do you have an A500K to try in its place? Will probably give you more of a useable range through the sweep.
