I’m looking for a way to get the gain staging right for my different guitars, going into a Helix floor unit.
I can add blocks on the Helix for dealing with different pick-ups e.g. I have a HSS HM Strat and EMG actives on a Steinberger, but that eats up vital blocks.
Ideally, I’d have a separate selector foot controlled unit, to give me the right levels for each of 3 scenarios and produce a relatively consistent output:
I’m not sure if I’ve ever actually posted here but thought I’d mention the gigrig 321 which is designed to do exactly what you mention - 3 switchable inputs to 1 output with preamp to match levels between instruments
I put my guitar pedals in the FX loop of an Eventide Mixing Link. Then, you can just use the master in knob to adjust for each guitar. Works a treat, and does so much more besides.
