I’ve had the AM EF for a while now, and I just haven’t been able to get a fat / round EF sound out of it. It excels at subtle sounds, but the overall tone seems a little chirpy / squirty—if that makes any sense. Overall it seems a little tame. Any other users notice this too? Any recommendations / settings for thickening things up? NOTE: My pedal is from the earliest run, which were built around actual, vintage MXR EF circuit boards (if I recall correctly). Are old MXR EF’s more subtle / tame sounding?
