Hey Danmaier -
For all the Brian Setzer trio stuff we take 3 inputs.. RCA 44 out front just above the bridge, a couple of inches off center. We put this mic a little closer than standard double bass micing - only about 7 or 8 inches out. If you don't have a ribbon, any LDC, or RE-20 kind of thing will work.
#2 is a neck click mic - a 57
, or a 451/km84 between the left and right hand of the player pointed slightly up towards the left hand. Don't try to get any real sound out of this mic - it should sound like a drummer playing the rim of a snare.
#3 is a DI with a little growl on the amp.
Record all three seperately if you can, - when it's time to mix, 9 times out of 10 I'll
use 100 % of the front mic, 20 % of the amp compressed to shit, for nastiness, and 15 % click mic.
The 58 in foam stuffed under the bridge is classic, and serves the same purpose as an amp if you don't have one.
hope this helps - happy new year - Dave Darling
