Slap a Mesa Boogie 5 band EQ in the loop of the Mark 5 and it will sound super heavy. The Boogie pedal can be had cheap on the used market. I paid $150 for mine used.
I have been thinking about this...... Getting either a Friedman JJ new or a Twin Jet and a Herbert both used, both used of course. The only thing is it seems like the Twin Jet and the Bogner both do the same thing......heavy crushing sound whereas the Friedman is that modded Marshall type of sound that is good for blues to metal.
Diezel VH4. $4000 to sound like Aenima. It's 3d sounding, but it's not overly distorted, like the 5150. It was just meh, for $1500 good, for $4000 a joke. Yes, it's versatile, if you like pristine clean and Tool, with midi switching.
