Got a decent deal on a Used Pro Junior at Guitar Center Saturday. My first all tube amp, as my Musicman has a solid state pre-amp. Love the sounds I get. Sounds great with my strat and pedals. Some hum and hiss but not loud. Separated the heater wires from the rest and twisted and moved them around a little but no noticeable difference in the hum. Not sure of the year but the pcb says 2005 so it can't be too old. My only real complaint is that it smells of heated up plastic or something when it heats up. They put some new tubes in so hopefully the smell is the tubes and will subside. Two fender groove tube sovtek preamp tubes and two Mesa el84's. Love the sound!
