1. Why does my amp lose "fullness" when Gain is at 5 or below, regardless of the Master Volume knob position?
2. Does switching from one mode to another (from lo > mid > hi) change the amount of harmonic distortion if the settings (EQ, Gain, and Master on full) remain the same?
3. Does Tilt knob, when set to 10 (which supposedly mimics the Hi treble channel of a Plexi) add additional gain to the overall gain structure (Gain knob + Master volume knob)
4. What frequencies does Middle knob control? Does it boost or cut certain frequencies or just shifts the emphasis of the middle frequency region?
I've checked the manuals I can find, but have been unable to get a clear reading on how loud the Origin 50Combo is.
Can anyone enlighten me on this? SPL or DB rating?
