As I post this, I know it sounds crazy, but; as has been stated, I have a saz1500v3, I was hesitant to attach the bass knob. The other day I put it in. Thing is, it sounds much better with it attached, there is a noticable difference. I have the gain on the amp at about 90%, before the knob, the gain was at half. The gain knob only has to be at maybe 25% to acheive the same output. Is this strange?
