Hi all,
Having a bit of a problem with my jmp 1 watt head and need some help. It was working fine last night through a 1960A cab, i usually have it on the 0.1watt setting and that's pretty loud through the 4x12. But i turned it on this morning and the volume had reduced to virtually nothing. There is still volume there but really quiet almost nothing in the 0.1watt setting with everything on 10. If i turn in to 1watt with the boost on aswell it gets up to a similar volume to how it usually is in 0.1watt but not really any gain/crunch.
Checked the guitar and lead on another amp and to make sure they were not the problem and they seem fine.
Has anybody else had a similar problem or got an idea what could be the issue?
Thanks
Dan
