I picked this up on a trade, and just don't have a need for it, as much as I need cash. It's serial number 245, but I have no idea how old it is. It seems to be in good shape, with a few minor scratches in the case on the sides and bottom. It doesn't look like it's been dropped ever. I plugged it in, and hooked up to my schroeders (first the 1210, then the 21012)... sounds great!! I used to have an M-Pulse 600.. and this certainly reminded me of why I like it so much. There are two extra Mesa 12AX7 tubes to go with it. I'll ship it to you (inside the 48) for $625.00. Paypal included. I'll get you pics if you want.
