Hi there,

I love the sound of my 22 Caliber power amp except from the terrible Earth buzz (particularly with distortion on).
Even get it with humbucker pickups.

I am using a proper speaker cable btw (in fact have tried 2 different high quality cables).

Now, I believe this is something folks have raised before. The hum reduces massively if I touch the casing of the 22 Caliber.
Does anyone know of a mod that I could carry out to ensure it’s earthed?
I’d like to play a gig with it soon but not with that much noise!

Don’t really want to get rid of the pedal but might have to…

cheers

MrB
