Hey i have a 1987x plexi reissue for trade with mullard el34 is in the power section and JJ teslas in the preamp. I believe this amp was produced in 1994, it is very clean and in excellent shape. It is a perfect starting platform for modification, but it does sound great on its own to my mis belief i thought this amp would have a decent amount of again. It really does have an excellent clean, and with the channels jumpered you can real get a big bottom end. It gets the really woody mid range marshall is known for especially when it is at volume. My reason for trading/selling is that i just got a Jmp 2204 Clone and want another flavored amp.I would trade this amp for a real cool combo like a mesa boogie stiletto, or a lonestar classic combo. Maybe a fender twin, bassman, cool guitars. I am not necessarily opposed to having another head either. It would be much easier if you live not to far from so we could just meet in person. I am in NY.
