Here are some audio clips of the KB-1 and various other preamps in mp3 format. Obviously, comparisons like this are limited due to limitations of file size and more importantly the variences in the recordings themselves .The audio clips are from 2 different sessions. They were recorded by the clients who have purchased the KB- 1. They are what they are. No attempts were made to make one sound better than the other. Bear in mind that slight differences in level will make an audible difference. I chose not to edit any of them but just leave them as is. In making these recordings, we tried to keep levels as close as possible.

The first session was of Doug, which consisted of his vocal with acoustic guitar. A Lawson L-4 as the vocal mic and I believe a pair of Rode NT-1s on the guitar. It was done as one take.

The second set was of a female vocal without background tracks. The mic was an AKG C-12
