Martin,
well it's hard to compare in so much as the tones are so different.
the Bluesmaster and EVM combo seems incredibly loud compared to the 102/celestion combo.
Obviously the EVM is an incredibly efficient speaker so that adds to the level too.
The clean on the BM is very sparkly and has 'girth' which I put down to the 100w. The OD seems to go a bit flat if you turn the master down to an 'acceptable' level in the studio. Maybe the clarity and power handling of the EV doesn't suit a great OD sound? not sure, early days yet.
I have been trying it out with a strat by the way, need to try the tele in the picture, regular tele and my 335.
I know where this is heading.........
clean sound from the BM....OD from the 102
no ones managed to make an amp combining the two.
