I know I'm continuing the bludgeoning of an equestrian creature past the point of termination,Boost trim fixed to 75% is roughly what my ears are telling me, when comparing my MBD-1s.
The taper on the gain pot I think makes a difference in how they're both reacting, for me.
I know it's splitting hairs, and you could probably line up multiple MBDs, play'em live, and not hear a difference.
But, to me, it's like the phenomena I see with people and Muffs from different Eras.
Except I'd much rather have an MBD-1.
But one notable difference I hear in the yellow script, is that a very hot bass, specifically my L-2000, actually distorts the clean channel.
The white script, and MBD2, don't exhibit this.
