Hammond EXP50J

I am not an expert by any means, but I bought this pedal to use with my Crumar Mojo 61 (with an adapter) and I am very satisfied thus far. The pedal is very satisfying to work with. The organ is an entirely different experience with a swell pedal.
The native Crumar pedals were about as expensive as this one, and they seemed a bit too heavy. While still expensive, I preferred an original Hammond pedal rather than a Crumar pedal at the same price.

NOTE: Crumar and Hammond organs both use a TRS cable for connections, but the Tip and Ring are by convention flipped on the two. (One has 5V on tip, signal on ring, the other one has signal on tip, 5V on ring. Both use sleeve for ground.) I bought two Y-adapter cables to makes up for this and to avoid soldering my own. It works perfect thus far (2 weeks, including 3 gigs/band rehearsals).
