could someone be nice enough to read this and give me an estimate of what my problem is?
i have a MARHALL JCM 900 SL-X 100WATT head, i run it through a MARSHALL 1960A cab. i have 4 effect pedals directly in line after the amp and then a
noise suppressor and a BOSS SD-1. and 2 RG7s
After playing for 20 mins or so my guitar sounds dull as.
and the amp really hisses, not like it used to.
also when i kick my SD-1 or tap on the metal parts of the amp i can hear it through the speakers very loudly.
WTF is going on?
Cheers
Michael
