so I came here.. I currently play a Gamma Alpha P bass with passive pups and a volume and tone nob, straight through to my SUNN 115. I recently had it cleaned and holly carp, this thing sounds like it is right out of the shop 30 years ago... The strings I play are super light and light strings and together with the amp I get a pretty hi tone. The amp has Volume, Bass, Treb, and Presence. I have messed with the settings but can't seem to find anything similar to what I want. Anybody have any suggestions beside getting thicker strings. I use the lights because of a finger injury.. Looking forward to some suggestions.
