Just got in from a 3 set gig with the Big Band down at Tempe Marketplace. Big train wreck for me in the first set. My Shuttle 9 started cutting in and out sporadically and totally losing output to the cab. The thing with the Big Band is its not like I can just tell them to stop until I sort things out. They keep going. NOT cool. And, thank God I spend too much time on here, because I had heard Andy et al talking about the effects loop causing issues. So, I was ultimately able to jam my tuning cable in and out of the effects loop jacks and get everything back to normal to finish the gig. But, it messed up a couple of tunes showtime. I have been gigging this amp for four years, and it has been solid until tonight. The thing is; I just can't have that happen randomly. Is the only long term solution to leave a jumper strap inserted into the effects loop to avoid this in the future? I NEVER use effects. Maybe I can just wire those two jacks out of the circuit permanently? Anyone else have this issue and find a permanent fix? I hate surprises on the gig.
