Jack Socket Crack

[number six]

I have a Sadowsky bass and recently purchased some Markbass equipment. At rehearsals one day there was an almighty crack which sent the 'clip' light blue, rattled the speakers and cut the sound. Oops.

I suspected the amp as it was new. Didn't happen again for 2 weeks then twice in succession. I started to check things out and it happened when I wiggled the jack plug in the bass socket. First move was to consult the experts at TB of course.

There's a post which mentions Monster cables a while ago being too large for the socket and widening the jack 'prongs'. I have a Planet Waves cable I've had for a couple of years but I thought I'd check anyway.

Unscrewed the Sadowsky jack and tried a few jacks out:

The Planet Waves jack (which also slips too easily out of one of the MB sockets) doesn't fit the prongs properly. The top prong should fit snugly into the recess on the plug - it doesn't as it sits on the top rim.

The Sadowsky cable fits like a glove and doesn't slip out of the Markbass amp easily either.

Problem solved and a second Sadowsky cable on order.
Saved me a trip to the guitar tech too. Hope it helps.
