The One Control Golden Acorn Overdrive Special is a compact overdrive pedal designed by Bjorn Juhl and built in conjunction with One Control. One Control describes it as a dynamic overdrive designed to catch a small window in which single notes can be worked to be seemingly clean or distorted, and says it was designed to reproduce the iconic overdrive and tremendous dynamic range of the renowned Dumble amplifiers1. In a One Control interview, Juhl put it this way: "A good example is the Golden Acorn, an overdrive that I designed to capture that "D" style amplifier that guitarists who" play them are after2. It sits among One Control's other Juhl-designed drives such as the Honey Bee, Baby Blue OD and SUPER APRICOT OD.
One Control's product page listed the Golden Acorn Overdrive Special as sold out as of 26 October 2026, with a regular price of $154.99 USD shown against a higher figure of $193.99 USD1.
The controls: Volume, Bright and Ratio
The Golden Acorn keeps its faceplate to three knobs. Guitar Pedal X summarized the layout as "Controls - Volume, Bright, Ratio (Distortion & Compression)"3.
| Control | What it does |
|---|---|
| Volume | Sets the effect level relative to the bypass level by adjusting the output of the effect1 |
| Bright | Sets how sparkling the sound is, allowing for a soft sound to one where angles sing on overtones1 |
| Ratio | Sets the depth of distortion and compression and is used to set the pivot point depending on guitar pickup strength1 |
The Ratio knob is the one that shapes the core of the sound: it governs both distortion and compression depth, and One Control notes it is set against the strength of your guitar's pickups, so the pivot point between clean and distorted shifts from one guitar to the next1. Volume then balances the effect against your bypass level, and Bright sets the top-end sparkle1.
Power, bypass and specifications
The pedal runs on a 9V battery or a standard DC power supply at 9 V, drawing 3 mA1. That low draw is easy on any power supply, and the true-bypass switching keeps the signal path clean when the pedal is off1. Other specifications One Control lists include an input impedance of 280 K, an output impedance of 25K, an S/N ratio of -86 dB, an aluminum enclosure, and a weight of approximately 160 g1.
Where it came from
Bjorn Juhl designed the Golden Acorn for One Control with a specific amplifier feel in mind: the Dumble-style amp, whose overdrive and dynamic range the pedal was designed to reproduce12. Juhl's designs for One Control cover a family of overdrives, including the Strawberry Red Overdrive, Persian Green Screamer, Tornado Drive and Cranberry Over Drive, with the Golden Acorn as the D-style entry among them12. For how this kind of pedal sits against other drives, see Overdrive Pedals or the Boss SD-1 vs Ibanez TS9 Tube Screamer comparison.

Questions
Does the Golden Acorn take a 9V battery?
Yes. One Control lists the Golden Acorn Overdrive Special as running on a 9V battery or a standard DC power supply, with a drive voltage of 9 V. Its current draw is low, listed at 3 mA, so a battery is a practical option for this pedal.
Is the Golden Acorn Overdrive Special true bypass?
Yes. One Control specifies True-Bypass Switching for the Golden Acorn Overdrive Special, so the pedal passes your guitar's signal untouched when it is switched off.
What does the Ratio knob do on the Golden Acorn?
One Control describes the Ratio knob as setting the depth of distortion and compression, and as the control used to set the pivot point depending on the strength of your guitar's pickups. Guitar Pedal X summarises it as the Distortion and Compression control.
Who designed the One Control Golden Acorn?
The Golden Acorn Overdrive Special was designed by Bjorn Juhl, working in conjunction with One Control. In a One Control interview, Juhl described it as an overdrive designed to capture that D style amplifier that guitarists who play them prize.
