Hi :-)
Ulf is always fiddling around with tremolo and sound ‘per se’, so he came up with some ideas and had some of the mods done himself.
3 jacks on the far left:
top: insert point between Vol pot and EQ
mid + bottom: preamp outputs
XLR: power supply only
Acc 1 + 2: Effects loop as usual
Ulf has the second version of the preamp (with the ‘faint tremolo’). We corrected this by changing the switch to a DPDT… Cutting the depth pot + stopping the Vactrol LEDs (like on the 1st version).
Things near right of the panel:
Push/push switch for adding an additional set of caps to C8 and C20 for slower/smoother ramp curves.
Pot below the swich: This one is wired as an expression pedal / remote and connected to the jack on the far right of the panel. This is used to have the speed control of the Moog Phaser ‘at hand’ while playing.
Pot with the curve / line marking: Additional possibility of altering the tremolo curve: This is R17 of the schematics ‘as a pot’ (C11 cut out), so the curve can be altered from slice-type square to near triangle.
