One Control Sea Turquoise Delay (OC-STDn)

What it is

The Sea Turquoise Delay is a compact digital delay pedal in a turquoise aluminum enclosure. The manufacturer describes it as having delay times up to 600 ms and only three controls plus a switch. Designer Björn Juhl says the goal was to simplify the controls while keeping versatility. The Kill/Dry switch removes the dry signal from the output, which makes the pedal usable in parallel setups and mixing or PA chains. What distinguishes it from other mini delays, according to the sources, is the Kill/Dry switch, the option to run on a 9V battery, and its simple control layout. Bonedo and Gitarre & Bass both found the sound clean, and Gitarre & Bass compared it to a position between a Carbon Copy and a Boss DD-3. Gitarre & Bass also said the pedal offers fewer adjustments than many mini-pedal competitors from Mooer, TC, or XVive, and Bonedo said it offers no additional sound variations compared with stronger competitors at this price. The notes do not establish a production history or era beyond a 2022 manual labeled v2.01. Retailers use inconsistent model names, and one source gives the origin as China and another as Japan, so the production details are not settled.

How it's used

Musicians use it as a subtle delay that can stay on, for slapback and vintage-style echo sounds, and in studio and PA settings where the Kill/Dry switch allows only the effect to be sent. Bonedo notes its use in a parallel effects-loop setup. Gitarre & Bass suggests it suits players who want a set-and-forget approach rather than detailed delay tweaking.

Suggested usage

• Set delay time by ear

  The pedal has no tap tempo, so set the Delay knob by ear to fit the tempo of the song.

• Work within 600 ms

  The maximum delay time is 600 ms. Bonedo notes this is usually enough in practice but limits longer echoes.

• Split Level and Feedback

  Use Level to set how loud the repeats are and Feedback to set how many repeats there are. Gitarre & Bass suggests this split for balancing the two.

• Use Kill/Dry only where intended

  For mixing or PA use, the Kill/Dry switch removes the dry signal, so use it only when an effect-only signal is the intended result.

• Plan cable placement

  Gitarre & Bass notes the power jack sits at an awkward angle under the input and the Kill/Dry switch is hard to reach on the left below the output. Plan cable placement on a crowded board.

What reviewers said

• Bonedo (Michael Behm, 2022)

  Gave 4 out of 5. The reviewer praised the workmanship, simple operation, quality sound, battery operation, and Kill/Dry switch. The main drawback was the lack of tap tempo, and the reviewer noted no further sound variations compared with stronger competitors at this price. The review is in German.

• Gitarre & Bass (2022)

  Praised the build and sound, describing it as high quality with clean repeats and no obvious digital artifacts. The reviewer found the feature set spartan and said it suits a set-and-forget player. The review is in German.
