Hey guys and gals. 66 year old wanna be here. So I am back in the game recently and have a rig I want to set up. In the past it was just an amp into cabinets. I never used effects or a separate preamp. I have a GK MB fusion 800 and GK NEOs 2x12 and 4x10. That was my rig I used to use and am using now. I recently acquired a rackmount Sans Amp RBI and a GK RB 800 amp. I also have a DBX 160x compressor from my "studio". My idea is to use one amp into each cab, one for a "clean" tone cab [the 4x10?] and the other into a "dirty tone cab" [the 2x12?]. How do I use the Sans Amp? Just into the "clean" cab? I also am in the process of building my first effects pedalboard that I wish to incorporate into this rig. [I have a Source Audio SA-143 filter, Digitech Whammy, the Chancellor Dunlop foot pedal, OC-5 octave, Kasleder Albatross, Darkglass B3K, tcElectronics Sentry, MXR Bass Chorus, Screen Violence and the Keeley Caverns.] I had this idea and now I am unsure of how to safely hook all of it up. I know I need a splitter. I am sure all of this can be done. But I need my hand held to guide me into the specifics. Simple things like do I use instrument cables to connect everything except the speakers? All these years and I never gave a thought about how to hook up anything other just a simple amp/cab rig. Then I got this crazy idea and started to buy shit. I guess finally having time / money / motivation caused all of this. And now i feel I am in over my head. Anyways I would appreciate the assist on how to hook all of this up the way I want it. Thanks in advance.
