Brand new Tung-Sol Tubes.  This should be listed as MINT but I did modify the Limit control to a Presence control. Much more tonal control, makes a remarkable difference. Also included "Studio Slips Clamshell" cover. $150.00 value. Also completely serviced at the same time (see last picture). This is one of the most underrated/underpriced amps out there. Its completely Hand Wired Great clean sounds, Great distortion sound also. Please look/listen to short demo video. I demonstrate shimmering clean, bluesy, distortion and jazz. Only reverb added: . The S.O.B. was introduced in the Mark IIC era. These amps were made from May 1982 to December 1985. Serial numbers started with 0100 and ended on 2390(this amp is 1928). This was Mesa/Boogie's first attempt at having a reissue of the Mark I. It had two cascading gain inputs and its controls were Volume(gain) 1, Volume(gain) 2, Master, Treble, Bass, Middle, Limit or Presence (depending on the version). No foot-switching available, however an A/B splitter pedal could be used to select input 1 or input 2 separately. These amps had a point-to-point wired power section and had large transformers with great headroom. This is a 60 watt version.
