Cor blimey. It gets better.
I purchased a DHA VTI-EQ-DI-STD from @TPJ
Tried it into front end of Helix, through monitors and phones. Then DI into the K10.2.
Blimey.
I have a few Preamp DI pedals but this is something else. The valve Preamp makes a massive difference - the K10.2 sounds more cab like than it ever has and the warmth, punch, definition and tone is unbelievable. I tried the 64P in and it just came alive.
Wow.
