The DI output will be at the end of the chain - also a TS output will be available also at the end of the chain. I can't see the advantage to have a DIY pre or post eq as the output of the preamp is balanced via DI hmmm i hope i've understood the question.
One more question to the new preamp:
Is the DI-Signal switchable pre-/post-EQ?
I want to give a clean Instrument signal to the mixer.
I'm very happy with my "old" Dexter's Preamp but reducing the DI-Box would be a great thing and spends more place on the board.
