Fender Jazz USA Deluxe 5 goes straight to a Genz Benz GBE750 head.
The GBE750 has two channels with individual effects loops.
FET channel loop: Send > Boss TU2 tuner > Digitech Bass Autowah > Digitech Bass Overdrive/Distortion > Digitech Bass Chorus > Digitech Digidelay > Digitech Digiverb > Bespeco volume pedal (nice for turning all fx off at once & blending) > Return.
I'm not endorsed by Digitech or anything, just figured all their pedals look nice together. Definitely in the market for a better distortion tho at least...
Tube channel loop sends to a Tech21 Bass Compressor & back. I like to have the tone of the guitar coming through, albeit with slight compression, as well as the effected signal. Keeps everything nice & solid when using effects that weaken your bottom end.
I use Genz Benz Live 4x10 & 1x15 for cabs. Again, not endorsed or anything, but I was offered a £2K rig for £1K...
All my effects are on a single board which comprises a little Behringer minimixer too. If playing thru someone else's rig, with less effect loops, I don't want to sacrifice that two signal sound. I hook the compressor into the second out on the TU2 to split the signal, then join them back up at the mixer, sending both to the amp. I can balance wet & dry signals with the mixer.
Quite a geeky set up but I love it, & it's always a conversation piece if nothing else...
