The Suhr Koko Boost Legacy Edition is a boost pedal that combines two boosts in one box: a clean, transparent boost and a selectable midrange boost. Two footswitches give instant access to each mode, so you can kick in the clean boost, the mid boost, or use them together, with the Mid control adding the chosen mid frequency on top of the clean boosted signal1.
Controls
| Control | What it does |
|---|---|
| Boost | Adjusts the overall output of the boost circuit, from 0 dB (unity gain) to +20 dB of gain1 |
| Mid | Adjusts the output of the selected Mid frequency (via the Freq switch) that is added to the clean boosted signal1 |
| Freq switch | Three position frequency switch, active when the mid boost is engaged, chooses between three midrange voicings1 |
The Boost control does more than make things louder. Suhr describes turning it to higher settings as efficiently pushing the front end of your amplifier and creating a broad range of natural overdriven tones, which puts the pedal in the same territory players use a boost for when driving an amp into overdrive1.
The three Freq switch voicings
The Freq switch only matters when the mid boost is engaged, and it selects between three midrange characters1:
- Left (Mids): Full and Smooth, tuned specifically to bring out your guitar's natural midrange characteristics1
- Middle (High Mids): Clear and articulate, voiced to cut through a mix for solo playing1
- Right (Low Mids): Fat and Creamy, described as excellent for thickening up rhythm and lead tones1
Bypass and buffering
The Koko Boost includes a buffer that Suhr describes as high quality and transparent sounding. An internal switch chooses between true bypass and buffered bypass modes, so the pedal can double as a board buffer if you set it to buffered1.
If you want to compare it with other Suhr boosts, the range also includes the original Suhr Koko Boost, the Suhr Koko Boost Reloaded, the Suhr Iso Boost, the Suhr Dual Boost and the Suhr Brighton Treble Booster. More broadly, it sits among boost pedals that offer both clean and voiced boost options1.

Questions
Is the Suhr Koko Boost Legacy Edition true bypass or buffered?
Both, depending on how you set it. The pedal includes what Suhr describes as a high quality, transparent sounding buffer, and an internal switch lets you choose between true bypass and buffered bypass modes. That means you can run it as a straight true bypass pedal or use it as the buffer on your board.
How much gain does the Koko Boost add?
The Boost control varies from 0 dB, which is unity gain, up to +20 dB of gain. Suhr notes that turning the control to higher settings will efficiently push the front end of your amplifier and create a broad range of natural overdriven tones.
Can I use the clean boost and the mid boost at the same time?
The pedal has two footswitches that give instant access to each boost mode, clean and mid boost. The Mid control adjusts the output of the selected mid frequency that is added to the clean boosted signal, so the mid boost works on top of the clean boost rather than as a separate, unrelated circuit.
How much does the Suhr Koko Boost Legacy Edition cost?
Suhr lists the Koko Boost Legacy Edition at $249.00 USD on its product page as of October 2026.
