Cheers Mark! Learnt from the best
And no problem AD. It's good practice for me.
Funny this came up...a bass player friend has recently found himself on guitar duties for another band and his Bass Muff just doesn't cut through so he asked me to build him something....then asked if I could show him the ropes on pedal building. This particular circuit would make a great learning experience for him (how caps affect bass response e.g.)
So we will be building this week. I'll report back when done.
