So I got a great deal on a good mint amp for my gui****. ROLAND BOLT 60. all tube power section, solid pre. reverb. 60watts 8ohms only. 2 6l6s and one 12a7. anyways the thing worked fine with guitars... plugged in my stingray and the input jacks seemed to go on a off. got them fixed. worked fine with guitars for couple of weeks. Decided again to try use the clean channel at home with my 8ohms boogie cab very low to use the reverb a bit and again the same problem. However I connect the bass thru the send thru the effects loop and the thing sounds awesome. I can even use the eq because the effects loop can be used pre eq... But the input jacks,,, the regular ones are dead, and this is for my gui**** and for recording, ew want the distortion channel and the whole works... SO BASICALLY IN A NUTSHELL.. im asking can a high output bassguitar damage an amp not suited for it...?
