Vic’s Bridge Wing Preamp
Quick Start: We recommend starting with your amp at a moderate volume and the preamp knobs at 12 o’clock. At this position, the unit outputs a safe signal level with approximately 6dB of attenuation on the mid knobs. Adjust the Red Knob first to set your output, then use the switches and EQ knobs to find the specific frequency control and tone you like.
Tone & Feedback Control
This single-channel preamp provides a clean, buffered signal via a TL072 preamp circuit. Its features are designed to manage feedback and to condition the signal of your upright bass pickup before hitting your bass amplifier.
Red Output Knob: Controls the master output gain on the top of the unit.
Polarity Switch: An instant feedback killer for loud stages; it changes how the pickup reacts to speaker sound waves.
70Hz High Pass Filter: A switch to cut out stage rumble and low-end boom.
Low Mid Knob (350Hz): Turning this clockwise reduces the "congested" or "boxy" frequencies that often cause low-end groaning.
High Mid Knob (1.5kHz): Reduces the "clacky" or "brittle" sound common with piezo pickups.
Connectivity & Versatility
Input: Features a 1/4” input. While optimized for Vic's Bridge Wing pickups, it works with other designs, string types, and magnetic pickups. Adapters for 2.5mm micro-jacks are also available.
Bridge Wing Pickup Performance Tip: For the best tone, ensure your pickup has a snug fit in the bridge wing. If the fit is loose, a small shim or guitar pick can help find the "sweet spot." More information about this can be found on the pickup page.
Product Specifications
(Dimensions include the protrusion of all knobs and switches.)
Power & Battery Life
USB-C Charging: Uses a 9V battery, but includes a 5V USB-C port and internal pigtail. This allows you to use and charge a rechargeable 9V without removing the back cover.
Battery Life: Confirmed for at least 24 hours of continuous run time with standard 9V and good quality rechargeable 9V batteries.
Smart Switching: An orange LED indicates power. When the switch is off, the battery will not drain even if your cables remain plugged in.
Mounting & Hardware
Tailpiece Mount: The unit mounts at the top of the tailpiece via a fixed Velcro strap and foam rubber pad intended to wrap around the strings. This ensures a firm grip that won't slide or affect the sound of your strings.
Pedalboard Ready: The Velcro strap can be removed for pedalboard use.
Easy Access: Includes optional thumb screws for tool-free backplate removal and an optional second strap with adhesive clips for a more permanent mount.
