The prototype has been reinstalled in the line up of basses.
It was neglected for years because of scratchy/faulty potentiometers.
Last week I decided to look under the hood once more in a last attempt to turn it into a more reliable bass.
I carefully opened op the ancient potentiometer and cleaned the inside with a cottontip.
Et voila! No more scratching noises no more drop outs! Yeehaaw.
Rehearsed with it this week. And I'm taking it to the gig tonite.
If I ever grow tired of it, you're the first to know Uwe.
BTW
Did you know the other prototype plus the guitar version fetched 42.000 USD last summer at the auction of Les Paul's gear?
