My signal chain was: Underwood pickup into the A-Designs KGB-1TF, then into my Apogee Duet and into Logic Audio.
The playing examples were all recorded direct from the KGB’s output.
I’m extremely impressed with he tonal quality I get from the KGB and love the sound my upright bass gets going through the KGB. Seems like A-Designs did great thinking about this pre amp and it’s multiple uses. I’ll be taking the KGB with me on all Upright bass gigs.
