Fantastic amp! check out the vid I made to show it off: https://youtu.be/j_Bjw51FdsY

I'm not sure if the model name is "112 RD" or just "Music Man 65" and I don't know if it is a 100w or 65w, but whatever it is, it screams. This amp is almost too loud for any practical application. It has a single Celestion 12" speaker, which is good for clarity and high-end sounds. I don't know the exact date of manufacture, but basically these were made from 1978 to about 82 or so... I'm not a very good historian. This doesn't have the foot-switch with it, but it does come in a Flight Case. Cosmetically, this amp is very used and seen the inside of every honky-tonk from Juarez to Montreal. It has always been serviced professionally and you can see from the video it is in good working order. If you are bidding on this amp, you understand the nature of antique electronics and you should be familiar with guitar amps and how to take care of them. If you are going to play live gigs with this, I would recommend having a professional amp technician take a look at it at some point. A classic tube amp shares a lot in common with a classic car, special care and risk are always factors. All that aside, this is a great amp. It can sound clean as a whistle, or dirty and all broken up tube distortion sounding... very versatile, and you definitely won't ever need more volume.
