I've been in the studio recording my 5-string Christopher DB all this week with a country/folk/rock band. The engineer/producer wanted me to track with just my pickups going direct because there is no isolation in the big room for a microphone. I'm running mostly the Vektor pickup at 75% and blending in about 25% Full-circle with the Headway EDB-1 preamp and DI'ing to the mixing desk. The tone I'm getting is the best I've ever heard myself recorded. The engineer is just blown away at how much 'wood' is in the tone while still being even and punchy in all registers. He told me there is no sonic reason to re-track with a microphone. This producer has tracked a lot of upright bass sessions and is a player himself. Man it feels so great to track upright and be able to hear every note go down so easy. Then I hear the playback with no eq and the bass just sits right in the mix.
