Hi there from Slovenia, I've just got EPIPHONE PR-4E ACOUSTIC PLAYERPACK with A15-C studio acoustic amp (#-Band-EQ and Chorus). Guitar is OK, but the amp has too much gain. Distortioin begins at 1,5-2 with guitar volume very low. It is imposiple to play at higher levels. Mic input is OK. Is this normal. You said, you have to put volume at 2-2.5, do you have the same problem?
