Andy West in NO TREBLE:

I don’t have any of that stuff anymore. I’ve pared it back. Now I’m using just a basic hi-fi rig. I guess they call it a full-range, flat-response type of thing. I am using Electro-Voice. I’ve got a sub-cabinet and a single 12 like a floor monitor kind of thing, so it’s like a mini p.a. Then I’m using a Line 6 Helix into that and it’s just you know. I was literally going to go with just a computer because I’ve been doing plugins forever and I know how to get exactly what sound I want to use with plugins. I was just really paranoid about technology failure. Technology is what I did, so my brain goes straight to that. We’re just not quite there yet.

Probably it's a ETX-18SP
