So, a few months ago, I play a three or four song set at a local bar on a Tom Waits Tribute night. Our trio is singer/acoustic guitar, drums and bass. Bar bass rig is an SVT-CL classic tube amp with an 8x10 cab. I'm the first bass player of the night. It's been many years since I've played an all tube amp through a heavy cab, but I'm thinking good times - it'll be like over 40 years ago playing my old Traynor YBA-1 Bass Master through the 2 x 15 cab, only better and punchier. And I brought the same bass as back in the day, my trusty old '68 Telecaster bass.
Wrong, it's a mud machine. But, whatever, not a lot of time to play with settings, and they all look reasonably middle of the road anyway with the master well before when the bars open, so I maximize my entire single tone control to treble and simplify. It's all good.
Last song is Downtown Train - we do some kind of cross between Tom and Rod Stewart, with a lot of dynamics - quiet --> loud --> quiet. Well, that's the way it worked out, too, but not as I intended. In the "loud" part, keeping in mind the context of our trio and loud not getting close to where I used to play the 35 watt Traynor years ago, I'm starting to dig in a little, and suddenly things start to fade. Then fade to nothing. The power light is flashing, and I'm up there faking it with no sound. The one thing I did right was turn the amp off before I left the stage. I told the sound guy.
I looked it up after and apparently some kind of tube protection circuit tripped. The amp cooled down for a set, and then seemed to work again. Being a bar rig, I have no idea what kind of abuse it's been through, but I will say my old YBA-1, in almost 50 years, has never, ever let me down like that.
Count me as "Not a Fan".
