I picked up the Martin this morning - fitted with its new Baggs I-Beam (replacement for the old Fishman Ellipse) - and just had to give it a blast in the shop before bringing it home. Great sound. With no EQ set on the amp, it gave an excellent acoustic sound, and I could drive it up to a gigasquillion watts if I wanted to (though I don't).

Looking at the Fishman out of the guitar, it actually appears quite cheap and nasty, and techie Graham was not impressed with it. Price for the Baggs? £150 - though I got a decent discount from John, my friendly shop owner...
