The One Control Sea Turquoise Delay is a compact delay pedal designed by Bjorn Juhl, the designer known as BJF. One Control credits its design to "BJF's innovativeness and circuit design," and Juhl says that he and One Control "managed to simplify the controls while maintaining the versatility and quality of much desired delay pedal." The pedal carries a list price of $169.99 USD as of 26 October 2026, shown on the maker's page alongside a price of $212.99 USD, and is currently listed as sold out1.
The controls
The Sea Turquoise Delay keeps things deliberately small: "The SEA TURQUOLISE DELAY has only three controls and a switch," according to the maker's page1.
| Control | What it does |
|---|---|
| Delay | Sets the delay time, from doubling to 600 mS |
| Feedback | Controls the depth of the echo |
| Level | Controls the output of the pedal, and therefore the volume of the echo |
| Kill Dry switch | Determines whether the dry signal is present at the output |
One Control describes the pedal as "extremely quiet, making it useful in the studio as well as in live situations"1.
The Kill Dry switch
The Kill Dry switch sits on the side of the pedal and determines whether the dry signal is present at the output. One Control explains its purpose this way: "This switch is useful when using mixing consoles and PA Systems where you may only require the effect for depth of sound"1. In practice, that means a player running into a console or PA can send only the echoes forward and let the venue or engineer handle the dry guitar signal.
Designer and availability
Bjorn Juhl is the designer behind the pedal, and the simplified control layout is his work: "myself and One Control have managed to simplify the controls," he says on the maker's page1. The pedal is housed in a machined and anodized compact aluminum case1. As of 26 October 2026, the maker's page lists the Sea Turquoise Delay as sold out1.

Questions
Who designed the One Control Sea Turquoise Delay?
The Sea Turquoise Delay was designed by Bjorn Juhl, known as BJF. One Control credits the pedal's design to what it calls BJF's innovativeness and circuit design, and Juhl himself says that he and One Control simplified the controls while keeping the versatility and quality of a much desired delay pedal.
What is the maximum delay time on the Sea Turquoise Delay?
The maximum delay time is 600ms. The Delay knob runs from a doubling effect up to that 600ms maximum, giving the pedal its range from short doubling to longer echoes.
What does the Kill Dry switch do?
The Kill Dry switch, on the side of the pedal, determines whether the dry signal is present at the output. It is useful with mixing consoles and PA systems where only the effect is required for depth of sound and ambiance.
Is the Sea Turquoise Delay analog or digital?
The maker's product page does not say whether the circuit is analog or digital. What it does describe is a versatile delay pedal with a delay time up to 600ms, three controls and a switch, in a machined and anodized compact aluminum case.
