no/low sound from one side of mesa 50/50

sleewell · Post by **sleewell** » Mon Feb 11, 2013 11:12 am

so i was all excited to try out my new bogner fish this weekend. got it all wired up in 4cm with my mesa 50/50 and digitech gsp1101. i have a boss fs 6 on order but right now i only have a single boss latching pedal so i was only able to play 3 of the 4 channels but it sounded awesome. not better than the mak4 but different, will be nice to compare them. i only plan to gig with one preamp but for recording i plan to combine different channels from both units and i think that will rule.

which leads me to my issue. the B side of the mesa basically has no sound all of a sudden. i have to turn it up to 9 to hear anything and even that is way too low and obviously not normal at all. i retubed the mesa about a year ago and have many hours since then but did not have any issues where it stopped working mid jam, it was working fine just a few days ago. the A side still sounds fine and is just as loud as normal.

going to take it to a tech but off the bat does that sound like something simple?

thanks,

bill

it sounds like it's a dead tube man. I know you said you just retubed it recently, but that's what it sounds like. Do you have some replacement tubes to try out?

thanks Billy, that is what i was thinking but wasnt sure.

i still have the old ones. but they are super old.

maybe i should just call Laura and get some new tubes.

Try the old ones to see if at least you can restore sound. If that works, get a fresh set from Laura for best tone. But the old tubes should be ok for the test.

Pop the tubes from side A to side B to see what's up. That way you will know how it responds with known working tubes.

If it fixes the problem then new tube time :thu:

If not, tech time

Good luck, mang!!
