I used to have an Axe-Fx III for a few years and now have an FM9 Mark II Turbo, and I always feel all Marshall models are too dark. Before I started using FAS, I'd been really into Plexi style amps and owned a few, Metropoulos Metro-Plex, Bogner Helios, Friedman BE-100, Suhr SL68 and Suhr PT100. One of my friends got a Germino Lead 55. So I've played nearly every one out there. They all sounded "overly bright" and "thin" if compared to FAS models. When I tried those models for the first time, I felt like I was playing a bass amp, or a Bassman, or a Super Bass? Well I've not played them. Anyways, those models just sounded too thick, muddy, not bright enough and a little bit too gainy. Even the Friedman sounded more like a Plexi to me. I got my FM9 a couple of months ago and I tried them again and I still felt the same.
In case someone asks, I was using my amps and a Suhr RL, and OwnHammer IRs loaded in Redwirez mixIR, then switched to Suhr RLIR but still using the same OH IRs. And I tried using the same IRs with the Axe, so it was a fair comparison.
Now with the new firmware, I tried 'em again and they still felt wrong. Any idea how to make 'em bright and why do FAS Marshalls sound this way? Thanks guys.
