- Carling SPDT switch. A previous owner installed (neatly) an external power jack, oddly with center positive, contrary to the almost universal BOSS trend.
- Both in/out jacks are labeled "TAIWAN" on the larger flange.
- The case has a number "021-005078-01" number cast inside, and a small logo that looks like the letters "dcp" inside an oblique rectalgle that's itself atop another "lined" rectangle.
- On the metallic case of the pot you can read:
- A-B (inside an octagon logo)
- HOTPOTZ - 1
- 100K-OHM 862
- TYPE EJ
- EXTRA LIFE
- One of the rubber feet, 'though identical in shape, is a coupla millimeters taller than the other three.... replacement?...
'Though it's indeed a Jim Dunlop wah it seems to be a "transition" model with Thomas parts.
Received as a present from a guy who received it as a present as well from a Canadian guy that was dismantling a professional recording studio in southern Spain back in '87. Been in a drawer since then.
Sounds fantastic. Very classy. In very good shape.
Now, some more detailed photos of the innards:
Note the DPDT Carling switch for true-bypass added by me
and the external power jack added by a previous owner
