Hey everyone,
I wanted to try to setup the 4-cable-method with my Helix Floor and my Marshall amp. I got I working, but there is something weird going on with the volume, I think.
Here is what I did:
I set the 4-Cable-Method up to produce a decent volume (not too loud, not too quiet). Both the Channel Volume and the Master knob on my Marshall are barely turned up, though. Much lower than what I would normally do if I just plugged my guitar into the amp.
Then I wanted to make a patch that would allow me to switch between the 4-Cable-Method (using my Marshall preamp) and a modelled amp from within the Helix. So I added an amp block and bypassed the FX loop block (bypassing my Marshall preamp), and BOOM, the volume coming out of the Amp nearly blew me accross the room. I'm lucky I'm not deaf now.
I addad a gain block after the Helix amp and I had to set it to -50db to be the same volume than with the FX Loop active, MINUS 50db!!!
Then I thought well maybe adding an entire amp from the Helix (preamp + poweramp) is way too loud, so I added just a preamp block from the Helix. This is a bit quieter, but I still have to reduce the gain by -30db to get the same level than with the FX Loop active.
The end result is not good either since everytime I change the snapshots (S1 with the FX Loop, S2 with the Helix Amp and the gain reduction), there is a short super loud POP sound, probably because it takes a few milliseconds for the gain bock to activate.
If anyone here familiar with the 4-Cable-Method can help me out, I'd appreciate it. I want to know if other people have similar experiences or if I screwed up my setup somehow.
Thx for your help!
