Regardless of how it "works for you", this is what works for me (40+ years, seedy bars to a stadium of 40,000) in my situations.
Soundmen love me and I keep it that way. Its just one less thing for them to think about.
The bottom line is most amps either have it this way or it is switchable. There must be a reason?!
Given the tech is not a problem, why not have the option?
Like I mentioned before, Quilter has had so much complaint about not having it (D.I. pre master),
they've said they're probably changing it in the next series of 800's.
It must not be just me...…...
Like I said, I love the tone of the Amp.
But maybe if the seemingly popular option of a pre master/post EQ D.I. were available,
there wouldn't be so many of these on the used market right now....
Because the Amp itself is great.
Bottom line, no more debate.
This is what works for me.
(And judging by the market, apparently a whole lot of others)
