I used to have a Yamaha RBX 5 and RBX 765 A, not fretless but they were nice, and I like the TRB 6 and Patitucci models............
for fretless I use a Pedulla Pentabuzz, Fodera Monarch Elite 6, Modulus Prototype 7, Zeta Crossover EUB and a Guild Ashbory.
I've heard good things about TC Electronic Chorus mentioned in Harald's previous post.
I use an ART SGX Nitro or a Lexicon MPX G2 (rackmounts) for my FX and for pedals a Digitech Bass Whammy ( all 3 have real nice Chorus) a Dunlop 105Q wah, also sometimes an ART Nightbass SE and a Digitech Bass Harmony Machine.
