I made a profile of my Universal Audio LA-610 MKII Preamp an uploaded it to rig exchange (-> TG UA LA-610 01).
I created the profile going from the KPA Direct Output to the Line In of the preamp and from its Line Out to the Return Input of the KPA.
Setings used: Gain +10, Level ca.7, both EQs on 0; Comp/Limiter bypassed.
This settings give a clean sound but with the typical tube grit and warmth that made this preamp famous.
I used a Fender American Standard Precision with Custom Shop Pickups for this profile.
Have fun! / Viel Spaß!
