Mics Used:

All captures were done using a Neve 1073 preamp.

Different mics were used on each cab, positioned in a variety of locations, listening and measuring to find "sweet spots." For some of the captures, the baffles or gobos were removed, resulting in a slightly roomier sound. These captures are indicated with RM.

This Cab Pack was engineered by Eric Killburn of Wellspring Sound Studio.
