Well he has his own signature pickup, wound by WCR. I don't understand why, because he was playing with Tim for some time, but hell, that's what he did: http://www.wcrguitar.com/IceBucker.html
Regarding the Larry Dino, yeah might be a souped up JCM800, but trust me, Larry is so mental when it comes to build quality, component choice and detail on the circuit, there will always be a difference between your "round the corner Marshall mod" and a Larry Dino939 (which also costs 5,000€ by the way).
sure
I'm very familiar with larry's obsession :lol:
larry is a genius, but technically, it's not that hard to tweak an amp to sound like that
if you isolate the drive channels, it's a very simple circuit with simple tone shaping tricks
larry himself said the fortin hulk mod marshall clips posted on rig talk sounded exactly like his dino does live, while the dino clip sounded muffled and very undefined
my modded marshall can't sound like that as it is, but it could with a little more circuit tweaking and experimentation, despite of building quality
I even had a framus cobra modded for a british tone that could get close, and it was a completly different amp, but the cobra different type of tonestack (a james tonestack instead of a marshall one) didn't allow the mids to crunch before the low end hit, so it always sounded so punchy and bassy that I couldn't get that schaffer crunchy thing
