USE WITH ACTIVE BASSES
Active electronics have higher output and typically generate more noise. To compen-
sate, we recommend lowering the volume on your bass. Additionally, experiment with
using flat EQ settings and/or decreasing the Drive, Character and Treble controls.
INSTRUCTIONS FOR RACKMOUNTING
1. Unplug unit. Remove top cover. Install rack ears with provided hardware. Replace
top cover.
2. Considering its weight, we recommend mounting unit on bottom of rack case.
3. If there isn’t enough clearance at the bottom of the rack case, detach the rubber
feet simply by removing the screws.
4. If there’s too much clearance (with or without the rubber feet) and you have a gap,
provide additional support to the rear of the unit (such as larger feet, wooden shims,
etc.).
