Hello everyone.
Does anyone have information on possible modifications for the Harley Benton GA5 & EpiPhone Valve Junior amplifier.
Thank you.
Dani.

Hey Dani - what are you trying to achieve? Most harmonica players like to swap out the 12AX7 type tub and put in lower gain 12AY7 for a warmer sound and less feedback.
