I purchased a used Mark IV and it has some issues that I hope this forum can help with.
Here are my issues:
- footswitch will not go to lead, no red led on footswitch or front of amp, footswitch feels good upon tap on switch, can be manualy switched with knob on back then Lead led will light and play, R1 and R2 footswitch work ok
- EQ front panel led lights up but real dim, stays on most of the time,
- R1 master level has no control over loudness
- Lead voicing switch on back feels "loose" on switch, meaning no firm click, and switch moves between up and down ( sure its broke)
Prev owner states tubes were just replaced.
Last question is were is the serial number located at, its a short body.
I've been playing a wide body for sometime, but it was a shared amp we payed 950 for a couple years ago, this one cost me 600 from a friend.
Thx in advance
