Ok guys I have a question about output. When I plug into channel 1 the volume knob is set on maybe #2 and it will deafen you. When I plug into channel 2 I have to turn the volume knob to 3 1/2 or 4 to get the same volume. Is this normal??? or should they both be close to the same. Now channel 1 has that select tone switch which channel 2 does not.
