I have built a few MV Marshalls and actually really like the 2004 style overdrive. But at the moment I'm using a slightly modified 50W '68 style plexi circuit in 1x12 combo and loving it. I have a couple of pedals which really work for dirt - both are fairly heavily modified versions of other things. And I recently sold my 1x12 JTM45 combo to a friend who keeps raving to me about it! The key for me has been building the cabinet out of solid pine similar to a Fender tweed cab. To me it sounds so much better than the heavy, stiff baltic ply cabs that Marshall use. The Marshall cabs squash the dynamics and make the amp more directional. Solid pine with lightweight baffles just spread the sound everywhere. You get more low end too. So my Marshalls sound like the tightest, toughest tweed amps ever.
Much lighter to carry too!
I love building this stuff.
