Just got one in a trade with good guy Mike Wiley and gigged with it last night. This is the John Entwistle signature version. Had it driving a QSC PLX 1602 and Bergantino HT115. Blues/Elvis Tribute pickup gig. Using a new Fender '51 Reissue P Bass. Man, talk about tone to the bone! Very impressive. Thick but not muddy with plenty of upper register if you want it. I was especially impressed with the EQ options and tube blend function. Tasty! I'll post pics if anyone's interested.
