Hey Invisibo..
The gear page is done with all the "toys".
Yes the delay unit is the TC Electronic D2.
The 4x4's are simply FX loops. You can turn them on and off individually to control different FX units. You use the loops so that the signal isn't going through every piece of gear all the time (which preserves the integrity of the signal). My rig is a stereo set up so each piece of gear uses 2 loops (left and right). The 4x4s then go into a "summing" unit on the back of the rack that then goes to the FX loop of amp 1 and just the return of the FX loop of amp 2. It also handles channel switching and sends the midi signal to the RS-10 (the Bradshaw
midi foot controller).
I haven't tried any of the baritone guitars yet.
