I'm serious !
I did not like the sounds I got from the Mk V...and I did not like tweaking for hours to get a decent sound...
I've got a Herbert Mk I for years and I'm probably too used to the diezel sound.
I plug and play...it sounds good. I'm quite lazy ! I even end up recording what I play, just for the pleasure to listen to the diezel sound without having to play ;-) LOL
Seriously, I never played the Mesa because I did not like it...I was always playing Herbert. So why keep the Mesa ?
I've sold it and bought a Hagen. And I'm happy with my both Diezels
