The other day, I noticed I had to crank the Output and Master way beyond 12 O'clock to hear anything from my Stiletto Deuce. Plus, the low E string was almost non-existant. No bass at all, with a crackling sound thrown in. Very thin and tinny. I was baffled.
The next day I plugged it up and played some and it seemed better. I was getting louder volume and crunch with Output and Master between 10:00 and 11:00. However, after 20 minutes of playing, I switched up to Bold and nearly blew my eardrums out!
I went to Spongy and it was lower volume and seemed to change on it's own! I flipped back and forth and finally I was getting nothing but ear splitting volume and put both Output and Master down below 9:00 and it was still incredibly loud. In fact, I don't think the Output knob even affected the volume, but the Master (all channel 2) could barely go to 9:00.
Sheesh, I was baffled. So I searched and found this thread. Is this the same issue all of you have had? Tube change for v5 then?
Has anyone else heard about this one? My Road King was working fine, and then the volume started to drop and then go into volume swells, sort of like a slow tremolo. Then, at times, it would give an ugly static buzz. Finally, the volume totally dropped. I first thought that it was a pre-amp tube, however, when I flipped the solo switch, on the back of the amp to bypass, I got volume on all channels, but no effects or reverb.
Well, I decided to just send it in to Mesa for Repair, so dropped it off at an excellent local music shop, to send in for me. I was thinking that it must be the circuit surrounding the switch.
I got a call from, Doug at Guitar Showcase, who gave me the following info. After trying to get an RMA from Mesa. The Mesa service rep told Doug that the problem sounded exactly like an issue that they had sent a memo out on. On Road Kings and some other amps, the effects circuit is partial to the Mesa Chinese tubes, rather than the Russian made tubes. So he recommended that I try to put a Chinese tube in and see if the problem clears up. The v5 slot is the one closest to the fan and furthest from the transformer. That actually solved the problem and the amp is back up and running. I'm not sure what it is that makes the Chinese made tubes special, but a $16 pre-amp tube is a much less costly resolution than sending the amp in for repair. I just thought that I'd put the information out there. If this is redundant to another thread, sorry, but I tried searching for it first.
I tried searching the Mesa site for this memo, and couldn't find it. And tried searching the BB for it with no luck. I did get a verification that Mesa Techs got this memo. Anyone else hear about this?
