Hello richard, I read on the big gearpage thread that the speaker on either amp breaks in over time to be less trebly, have seen some of that happen here already. I have rolled off the prescence meantime, its in the software on the 50watt
Have you tried the marshall I+II on sneakyamps via flooroard?
There's also a boss EQ and parametric EQ in there to shape your tone. There are some high gain patches by the posters Elantric and Beano, and Beano has great youtube video examples using the head into a cab
http://www.vguitarforums.com/smf/index.php?topic=20799.0I'm not really a high gain guy, more clean to crunch -I use the amp clean setting ( which is JC-120 ) and then have setup the presets from floorboard with clean twin, deluxe crunch and marshall 1+11, and use bluesdriver or treble booster on low for crunch
I appreciate its not for everyone but I love this amp. I actually really liked the 50watt, its just that I was selling my tube amp and have a pedal board and I found that (to me anyway) my pedals weren't as good into front of the amp as they were into my tube amp. The effects loop on the 100watt is excellent.
