One Control Baby Blue OD

The One Control Baby Blue OD is an overdrive pedal designed by Björn Juhl, the Swedish designer behind the BJF and BJFe brands, and built by the Japanese pedal company One Control as part of its BJF collection of effects¹. It is based on Juhl's BJFe FUZZ 1 circuit, which dates back to 2000, and One Control describes it as a discrete circuit that combines dynamic overdrive and fuzz². Premier Guitar's launch coverage put it plainly: "Baby Blue OD straddles the line between overdrive and fuzz"¹.

The gain is heavy enough to handle hard rock, but the pedal can also produce overdriven amp sounds with the Drive control dialed back¹. Juhl has said the One Control version is his best rendition of the circuit yet, and the inspiration behind it was the distorted guitar sound he assumed the first Fender amp he ever saw would produce¹.

Overdrive, fuzz, or both?

One Control sells the Baby Blue as an overdrive, but the descriptions from several angles agree that it sits between the two camps. One Control's own product page calls it "a discrete circuit that combines dynamic overdrive and fuzz"². An independent technical analysis of the original BJFE version goes further, noting that it "is described as a dynamic pre-amp tube distortion, although it is technically more of a fuzz pedal"³. Premier Guitar's press coverage frames it as a pedal that straddles the line between overdrive and fuzz¹.

For a player, that means the Baby Blue covers ground a straightforward overdrive does not. With the Drive control dialed back it produces overdriven amp sounds, while turning it up yields gain heavy enough for hard rock¹. The original BJFE circuit used diodes labeled 2A1200 for clipping, and builders recreating the circuit have used silicon diodes in their place³.

The pedal is a full-size unit, which Delicious Audio noted was notable for a company known for manufacturing high-end mini-pedals⁴. It comes in a high-quality aluminum enclosure, measures 31 (W) x 113 (D) x 61 (H) mm excluding knobs, and weighs 295g².

Controls

The Baby Blue OD keeps the control set of the original BJFe design: three knobs, one LED, running on 9V⁵.

Power and connections

The pedal runs on 9V DC with a center-negative plug and draws only 1.5 mA, which makes it easy to power alongside other pedals on a typical supply². It uses true-bypass switching, so the signal path is out of the circuit when the pedal is off². Input impedance is 240 K and output impedance is 25K, figures listed by both One Control and Delicious Audio²⁴.

History: BJFe FUZZ 1 and the Baby Blue

The circuit behind the Baby Blue OD is Juhl's BJFe FUZZ 1, originally released in 2000². Premier Guitar's 2018 launch coverage describes the lineage: "This original BJFe design dates back to 2000, when Björn first assembled the hand-made version"¹. Delicious Audio repeated the same account at the launch⁶.

One Control introduced the Baby Blue OD in 2018 alongside the Super Apricot OD, both added to the company's BJF collection of effects¹. Premier Guitar reported both pedals were shipping to dealers as of May 2018, with an MSRP of $249.00 USD¹. The One Control USA product page currently lists the pedal as sold out, with a regular price of $259.99 USD².

Juhl himself described the One Control version as the culmination of the circuit's development⁶¹:

Delicious Audio's news coverage of the launch noted that the Baby Blue OD joined the BJF collection of effects alongside the Super Apricot OD, with a $249.00 USD MSRP⁶.

Where it sits in the One Control BJF range

The Baby Blue OD is one of a large family of Juhl-designed overdrives in One Control's BJF collection, alongside pedals such as the Honey Bee, the Persian Green Screamer, the Strawberry Red Overdrive, the Cranberry Over Drive, and the Golden Acorn Overdrive Special¹. What distinguishes the Baby Blue within that range is its position between overdrive and fuzz, where most of its siblings are more conventional overdrives¹.
