I picked up a rather unusual/unique JCM 800 a few weeks ago. Just had it recapped a few days ago, and finally got around to taking pics of it earlier today for you guys to see.
What I have is a 1985 CSA JCM 800 model "1992" (100 watt bass model). After spending hours scouring the interwebs, I have not found another like this one.
Anomalies:
-Under the "JCM 800" print on the front panel, "BASS SERIES" is missing underneath.
-Back panel- left side is blank. Should have "MK II SUPER BASS 100w"
-These JCM 800 bass heads had "SLOPE" & "MID SWEEP" controls, mine has your standard guitar layout of "presence", "bass", "middle", "treble" & "volume I" & "volume II".
-These bass heads came with 2 inputs on the front, mine has 4..Similar to the 100 watt non-master (model 1959)
-Has a Baxandall tone stack.
My amp tech compared the amp with the model 1992 schematic, along with the model 1959 (100 watt non-master super lead) schematic..My amp seems to have features from both, which is unusual.
Anybody seen one like this before?
She sounds great by the way (with guitar). Classic Marshall hard rock tones straight in when cranked (nice cleans at lower volumes), and with a boost/OD in front, nails the old hard rock/early metal tones. Haven't tried it with bass yet, but my tech did in his shop and he said it sounded very good.
