Passive 0dB and Active -6dB Input Jacks
These are the instrument inputs. Use the Passive (0dB) Input for bass guitars that use passive elec-
tronics such as single-coil, split-coil and Humbucking pickups. Use the Active (-6dB) Input for hot or
active pickups. These inputs are not intended for connecting more than one instrument at a time.
Tip: use the -6dB Input if your bass is hot, whether passive or active and you play your bass at full
gain and you pluck the strings hard, this will reduce input clipping when not desired.
Tube Gain Control
The Tube Gain Control is a volume adjustment for the tube preamp, which features a single 12AX7A
Dual Triode preamp tube. The Tube Gain Control should normally be set around the middle, which
should be the optimal position for most basses. If your bass has an unusually low output, increase
the Tube Gain Control to a desired level, and for higher output basses use a lower setting. Increasing
the Tube Gain Control also affects the level of drive when the Tube Drive feature is engaged.
