I can't get YouTube here at work, so I'll check the link later Kaz :)
As for my amp, it's a slightly different spec to the regular Ceriatone amp. Mine has the Martamp setup of fewer carbon comp resistors to keep the noise floor as low as possible. There are still a few in there in the places where they add some mojo though ;)
It has Ceriatone transformers throughout, Shuguang KT-66s, JJ ECC83Ss etc. There are a few other parts that Martin put in that are slight upgrades, such as valve bases and fuse holders etc, plus mine has a Post Phase Invertor Master Volume (PPIMV) too.
Myself and Martin took all my amps to a rehearsal room last night to do back-to-backs at gig volume. I thought the 45/100 needed a bit more clarity after playing it at home, but in the end we changed nothing. Until yesterday I thought my JTM45 was my best sounding amp, but I'm loving the 45/100 more now I've heard it at gig volume. Once you crank it up it gets into it's stride and does what it does superbly. This is NOT a low volume amp - it only works properly when you crank it over half way on the master, and that's when the tone REALLY comes out.
I told Martin last night that he's not allowed to build any more as it's MY amp and no-one elses :twisted:
