Now that sounds like it's glorious! I'm thinking of slaving some of my Mosfets through my Mark IIIs power section to give them more bottom oomph. I have my JCM2000 DSL50 and 100 but something is telling me to try them through the Marks first. Ever try your JCM800 through your Boogie?Ever since I matched my Mesa/Boogie 50:50 stereo poweramp with my MarkIV head, running the lot through a re-wired 4x12 cab, it's game-set-match.
Yessir! Rocktron Velocity 300 powering the modeler in stereo to the 1965s...Boogie theile cab with an old EVM12L for the center channel in the W/D/W setup...really a HUGE sound in a relatively compact rig.Now that's a sweet tidy rig! Are those 1965 cabs?? And an EV extension? Dang!
I use the Matchless model pretty much exclusively with the 11R (and EPSi for IRs) and it really compliments the Mark IIB. Chime and mids! 1965 cabs are one of the best kept secrets from the Marshall lineup, IMO...can't figure why they ever quit making such a killer, and lightweight, cab!
