I saw on another forum the mark 3 on sale, and after some days waiting, I finally got one. its a mark 3, blue stripe, 100w, class a/simul class switch, reverb, graphic EQ, travel-transformer (110v-220v). its been modded with the presence-mod (so the sweep is more even, not as radical as it was before) and the c30 cap (to make it MUCH less bright than it was). I can run it with treble on 10 now, without it being harsh or shrill.
I really like the bright, complex, transparant yet mellow clean. the overdrive (lead) is SUPER tight! its so, so agressive. its much more agressive than any mark I've ever tried, including the mark 5. I really REALLY like this amp!
