For your amp, look into getting a used, non-master volume Twin Reverb from the 60' thru the early 70's ( "blackface" thru '67, "silverface" '68 thru the 70's). A master volume without the pull-out boost feature would be OK also. The newer re-issue '65 Twins are not the same animal ( circuit board vs. point to point wiring among other things ). The '70's silverfaces would probably fall more into your price range ( less $$$ than a new reissue) and would be a great buy. It may need a maintenance tuneup, ( cap job, retube and re-bias ) but in the long run would prove a greater value than a new reissue - and it will last longer - they were built like tanks.
