I have a theory on how this would work, but I can’t find any literature regarding the matter... Recently I’ve been looking into the possibly of running a bi-amped rig- bass amp + guitar amp. I probably wouldn’t want to go lite on the preamp drive sections, especially with the guitar amp. I enjoy my drive and fuzz pedals, too. Things will get noisy and I don’t want it to be that way between notes or when I’m not playing... I own a Boss NS-2 that I haven’t used for the better part of 5 years because I never quite got it to function the way I needed it to. My sustained notes weren’t sustaining in conjunction with my drive pedals and noisy pickups. How dare they! Regardless, past me planned on selling it until I realized I may not have been using it properly. I also own a Boss LS-2 that I haven’t used in some time because it lacks phase inversion on one of the loops. Now, in a theory that hasn’t been put into practice, I feel as if I could use them to achieve what I eventually want to do - suppress excess hiss and hum coming from drive pedals, etc. going into the preamp sections of 2 different amps in a bi-amped rig. All I would need to do is to purchase something like a Saturnworks Active Splitter and I’m set...... maybe? Without the use of any FX pedals, this would be the signal chain: Bass out > NS-2 input NS-2 send > LS-2 input LS-2 send A > Guitar Amp input Guitar Amp FX send > LS-2 return A LS-2 send B > Bass Amp input Bass Amp FX send > LS-2 return B LS-2 out > NS-2 return NS-2 out > Splitter Split A > Guitar Amp FX return Split B > Bass Amp FX return I do have concerns on where to place high gain pedals in this setup, amongst others, but I’ll leave it here for now. I have learned a lot from the TalkBass community! I do appreciate any input. I look forward to the responses!
