A buddy of mine now has a pawn shop and I dropped by to check it out. What caught my eye was a Marshall head sitting in the back. I took a look and asked him what he wanted for it. Under 200 bucks. I had never heard of it and the serial number put it as a 1990. I did some research and found it was a Solid State Lead 100 Mosfet, 3210, 100 watt, 2 channel amp. I brought it home and plugged it in to my Avatar 2/12 and was amazed at the tone. It has a really nice clean channel, spring reverb and a gain channel. It takes pedals really well and you would swear it is a tube amp. Most of the people who responded on Wiki gave it very high marks, and I can see why. True Marshall tone all the way, and the reliability of SS. I used my two button Marshall footswitch and the channels switch smoothly. It has Master volume, reverb, bass, mid, and treble controls, normal channel volume, and on the gain channel tone, volume plus a push pull eq . It also has rear speaker outputs and a volume control on the outputs. Everything works perfectly and it is almost 20 years old. Not a mark in the Tolex either.
I would say if you ever run across one grab it.
