I really would love a nice Tone Bender which I failed at this holiday when the Bone Tender went on sale. *facepalm*
I just wouldn't have gigged it...it would have been for fun/experimental recording.
Another one I have seen everywhere but have yet to own or play with myself is the Stereo Deluxe Memory Man which seems to be amazing. Also the DD-500 looks like it was made for me and I have yet to see or touch or hear one in person.
Moog MF-102 Ring Modulator. I've played with its simulation on the Bias FX and love it. I wish the real one wasn't so huge and expensive. If Chase Bliss did a ring modulator similar to the Moog, I'd definitely buy it.
subdecay- harmonic antagonizer
eqd- transmisser (maybe get one this month..)
eqd- all the other ones
all the stuff seen on knobs...
