Just bought a rather shabby HD 130 Reverb head as a gamble.
This is my first Music Man.
The first thing you see is that Ch2 Inp1 jack is missing and that the pilot light only lights up when the HiLo switch is in Lo. Also that the reverb tank in gone.
Checked inside and sees that the HiLo switch is bypassed and really only turns the light on (Didn't look too closely if it was connected like Hi or Lo). Also see that the Ohm selector switch is bypassed and only the 4 ohm cable is used from the output transformer.
It has JJ E34L tubes in it.
Anyone have a guess as to why it is the way it is?
