I thought it might have been because i reconfigured my g system.. but when i just go straight into the amp. channels 3 and 4 will work. 1 and 2.. nadda. ive checked settings.. cables.. switches. just totally blank here.

can a bad preamp tube be the cause of only the distorted channels working? i dont know if some preamp tubes are for some channels.. some for another.Check your preamp tubes if you have a back up or a tube that you know to be good try swapping out the preamp tubes one at a time start with v1 then v2 work your way through all of them or untill you find the bad preamp tube if it is in fact a bad preamp tube, also try cleaning your effects loop
Were you using the G System relays to switch channels on the Roadster? Ive read you're not supposed to do that as it can damage the amp...probably not the cause of the problem but still worth mentioning![]()
i didnt mention that when i crank the amp. like master volume to 10. the clean channel will work very quietly. still mean anything?
was a bad preamp tube!
i replaced it with a really old mesa one full of fingerprints. hope its okay =\
