TBH, the distortion that Lemmy achieves isn't "full gain", but full volume. It's a lesson I've learned over the years of playing with guitar amps & the near endless search for the "perfect" distortion sound.
Using full gain, and most OD/Dist/Fuzz pedals loads the pre-amp, and creates a "spiky" or "jagged", rough sounding distortion that's not very pleasant IMO.
Using a valve driven power amp, at full volume, creates a much smoother sounding distortion, usually described as "creamy". Mixed with a medium/medium-high gain, it gets that aggressive sound that's just gorgeous IMO. When I was playing guitar in one band, we played a few All Dayer's, and I had the other guitarists asking how I got that sound.
Anyway, new discovery for me, but I heard "Clatter" over the weekend and was very impressed. A 2 piece band, just bass & drums, check out "Tree of Secrets" on You Tube. [url]http://www.clatter.com[/url].
