Re: Another JS2480 Sustainiac quirk
Just had this reply from Alan at Sustainiac support, and interestingly my bridge pickup does seem very low (only just proud of the pickup ring), so there is some adjustment to do...............
"In the middle position (Mix mode) the sustainer output signal goes through the 22uF capacitor. If the cap is shorted, you will simply get Normal mode in that position. It is possible that the cap is open. If so, you can tack-solder another to the original cap’s terminals. If that makes it work, then you can replace the cap.
Mix mode is the weakest of the 3 modes. It could be that your bridge pickup and also the Sustainiac driver are set way to far from the strings. Both should be set to approximately 1/16 inch from the little e-string, and 1/8 to 3/16 inch from the big E.
