The Weehbo Tackleberry is a preamp pedal particularly designed for use with bass guitars and amplifiers, built around the boost circuit from a legendary 80's bass head. RockBoard's PedalPedia describes it as a Class-A JFET Bass Preamp, and it sits somewhere between a preamp, a clean boost and a light overdrive: it can push a signal up to 23 dB clean, or add symmetrical or asymmetrical clipping when you want some grit12.
Where it came from
The Tackleberry's circuit is based around the boost circuit from a legendary 80's bass head, according to Delicious Audio's product page. Weehbo designs, engineers and hand builds the pedal in Germany1. That bass-head heritage explains the pedal's focus: it is a preamp made to drive bass amps, with filtering shaped for bass frequencies rather than guitar.
Controls
The Tackleberry keeps things simple: two knobs and two toggle switches cover everything1.
| Control | What it does |
|---|---|
| Gain | Controls the input signal fed into the JFET gain stage1 |
| Level | Sets the desired output level, providing up to 23 dB of clean boost1 |
| Clipping toggle | Three options: off, asymmetrical, symmetrical1 |
| Bass toggle | Three bass response options: full, medium, less1 |
The two toggles are where the Tackleberry's tonal range lives. The clipping switch chooses between no clipping at all (pure boost) and two flavors of soft distortion, symmetrical or asymmetrical. The bass switch sets a high pass filter with three cutoff points1:
| Bass setting | Filter |
|---|---|
| Full | Low cut @ 75 Hz for full bass spectrum1 |
| Medium | Low cut @ 150 Hz for medium bass response1 |
| Less | Low cut @ 210 Hz for rolled off bass sound1 |
The "less" and "medium" bass settings cut low end at 210 Hz and 150 Hz respectively, which is useful when running the pedal into a guitar amp or when you want the Tackleberry to behave more like a guitar preamp. The "full" setting at 75 Hz keeps the whole bass spectrum intact.
Power and bypass
The Tackleberry runs on 9V DC, center negative, and draws 30mA2. Delicious Audio specifies a standard 9 volt DC power adaptor with a 2.1 mm negative tip inserted into the DC jack to power up the pedal1. When bypassed, the pedal is true bypass with relay and soft switch, meaning a relay handles the audio path and the footswitch is a soft electronic switch rather than a hard-wired mechanical one1.
Using it on a board
Delicious Audio suggests the Tackleberry works well as an always-on, first-in-chain pedal, or stacked with other gain pedals and fuzzes1. As a first-in-chain always-on preamp, the Gain knob shapes what everything downstream receives, and the Level knob can push the front of an amp or the rest of the board. Its bass-oriented filtering and JFET gain stage make it a natural fit among bass pedals, but the clipping and filter options give guitar players settings that suit them too.

Questions
Is the Weehbo Tackleberry only for bass?
The Tackleberry is a preamp particularly designed for use with bass guitars and amplifiers, and its bass response filtering reflects that. However, its clean boost and optional clipping can serve guitar players too, and Delicious Audio notes it works well as an always-on, first-in-chain pedal or stacked with other gain pedals and fuzzes.
Is the Weehbo Tackleberry analog?
Yes. RockBoard's PedalPedia lists the Tackleberry's circuit type as analog. It is a Class-A JFET preamp with clean boost and optional clipping, with no digital processing involved.
Is the Weehbo Tackleberry true bypass?
Yes. Delicious Audio describes the Tackleberry as true bypass with relay and soft switch, so the pedal's switching is handled by a relay rather than a simple mechanical footswitch.
What power does the Weehbo Tackleberry need?
The Tackleberry runs on 9V DC, center negative, drawing 30mA according to RockBoard's PedalPedia. Delicious Audio specifies a standard 9 volt DC power adaptor with a 2.1 mm negative tip. There is no battery option mentioned, so plan a power supply output for it.
How much clean boost does the Weehbo Tackleberry give?
The Level knob sets the desired output level and provides up to 23 dB of clean boost, according to Delicious Audio. The Gain knob before it controls the input signal fed into the JFET gain stage.
Where does the Weehbo Tackleberry go in a signal chain?
Delicious Audio recommends it as an always-on, first-in-chain pedal, or stacked with other gain pedals and fuzzes. Placing it first lets the Gain knob shape what the JFET stage receives before the rest of the chain.
