as i can afford it i've been fixing up a beat to snot early 80's JCM 800 2204.. The Canadian issue one.... just got it back from a tech today as i had him remove the high gain mod... but i've noticed a new issue i never noticed before.... I didn't request any other work done besides the high gain removal so it's not the techs fault i guess... unless it was an issue from removing the mod.
Anyways when i plug into the High Imput i get a fair bit more noise and distortion on low notes-(more then should be normal i figure, the low end distortion on notes made me think maybe something is wrong with the speaker)
when i plug into the Low imput i get almost 0 noise and no low end note distortions...
When i unplug the instrument cable from the front of the amp all together i get some noise like having a guitar cable in the amp but not in the guitar... like an open ground somewhere in the imput...
so i assume there must be an issue somewhere with the high imput jack? would this be wrong?
this 800 has sure been a lemon.... i knew that going into it that it was a real fixer upper... but still it has never worked right since i bought it....
