There is a thread on here somewhere about these. I have one. Some of the thread detailed re-wiring the neck pickup (series to parallel) to get rid of some of the mud on the two pickup version (mud + J), a useful mod. I had a single pup version for 3 days, when Thomann sent the wrong one! It was B stock, I got the replacement from a UK dealer.
I also re-wired the mult-way pickup switch, adding another volume knob, one for each pup.
Weight about half a kilo more than a P. Pity they went, not too many 32s about. Don't get on with 30s, just can't get strings that I like.
