Nice family you collected! I like the little Masteramp! It looks so clean!
Ralf
thanks. That is actually a 1957 66J. although it says "Masteramp" on the front badge, it says "66J" on the top. It is pretty clean, came with a cover that looks just as old as the amp. I got it from the original owner's grandson. I asked him "where is the guitar???" he said he sold it about 6 months ago, but it was also a 50's Guild.
I will add to, and update, the sticky reference thread that Captn started.
