This is advertised on Basschat, but might as well try it here too.
I'm having a clear out of things I'm not using.
This is a difficult one to price, on the one hand they aren't at all common, on the other it is full of bumps and dinks.
The speaker has been replaced with the nearest current Celestion equivalent, as it had had a drop which detached the original magnet.
It has a lovely sounding reverb, and a very useful sweepable notch filter for fixing troublesome frequencies on acoustic instruments.
It can be mounted on a mic stand for use as a personal monitor. I used it in the house with electric bass with the bass control turned down. Very usable at wife-friendly volumes! Also comes with a soft carry bag. Just over 7x7x7 inches. Collection only at the moment please, Oxfordshire
