Hi everyone, This is my first post, hopefully its in the right place. Maybe there's a noise-floor/amp channel jumping sticky or tutorial page someone could direct me to? My Wacky Setup... I'm trying to get the perfect tone with what I have. The best tone I can get is by piggy backing a Fender Prosonic head with a Fender Twin Reverb '65 RI. The Prosonic feeds effect send to channel one on twin (in 2), which then is jumpered to channel 2 (in1>in1). I'm using an older, factory rebuilt Earnie Ball A/B stereo pedal to feed each amp head: A> Prosonic (input 2), ...B> twin channel two, (input 2).... -when I rock one way, its Prosonic routed through both channels of Twin -rock the other way its just clean Fender Twin Reverb. The best sound I've ever heard from my setup is clean channel Prosonic routed to both channels of Twin in this manner. I use a dummy load on the Prosonic, with volume between 2-4 Questions... By experimenting I found some weird noise floor stuff happening. I get a high noise floor if I decide to ditch the A/B Pedal and just go through the Prosonic head (which feeds the twin... ch1 jumpered to ch2). As soon as I patch the second output on the A/B pedal to ch2 on the twin, the noise floor problem goes away. Even when I have the pedal rocked toward only the Prosonic. Its like the Twin Reverb Amp wants that open hole filled. Any idea why??? Ok, so as long as every hole is filled on the twin all is fine UNTIL I want to patch some effect pedals. Now if I patch a big muff (battery) in front of it all, noise floor still ok. As soon as I patch delay pedal (with wall wart) noise floor goes WAY up. Even with nothing connected to its input. Pedal wart is in same strip as both amps. I tried lots of different cables, long and short, between delay and A/B pedal and only discovered very minor changes. Just going direct into either amp, the delay pedal is super-quiet.(WTF???) Custom wiring ...And since I'm going through all this I'm going to make a custom wiring setup. Does anyone have a recommendation on best cables to use for this type of setup? Or best DIY cable recipe for low noise/high sonics? Any ideas, or references to other posts or pages great appreciated thanks!
