+1 on EVM12L.
I'm not sure if the Bluesmaster is best for JM tone foundation or not, but keep in mind JM plays amps ultra clean and uses stacked OD pedals for his blues tone. I guess this model would be best maybe for his Trio tone, but for most of work/tone, I would think if JM had to use a Ceriatone, it would be OTS 100-watts - just my opinion/guess.
I haven't heard a HRM BM(or any D-style amp) in real life(playing it myself I mean), so I'm not really able to say which one I'd really want.
I'm in the oppotunity to check out a HRM 50W...which I'm certainly going to do...just to see what it sounds like. I surely want a 100w model though.
Is it true the HRM is more modern than the BM, but the BM is more modern than the OTS?
I really love JM's tone...for example on the "Where the light is" DVD. Does he ever use the drive channel on his amps or is it really just the clean with pedals? I'm a "clean amp-dirty pedal" guy myself, playing a Twin Reverb and/or Sound City 50+(in stereo) so I like that setup very much.
But...I want a different flavour too...and that comes with a new amp too. I love Mayer's tone...but there's Santana and Bonamassa too, so....does it make sence I want an Overtone/HRM(BM)?
On the speaker story....so the G12-65 and EVM12L are favorites for a lot of people...how about a mix of speakers? Maybe one of both of these?
Oh...another question...What's with the effects-loop? I'm reading the standard loop isn't really happy with too many pedals or long cables?
