Detail 01
20–450 ms delay time
Covers doubling and slapback up to just under half a second. Long, spacious repeats aren't possible here.

Independent shopping perspective
The Korena take
Analog delay with 20–450 ms of repeat time and three knobs. For players who want short slapback to medium echo and nothing to program.
Strong match
Who this is for
- Rockabilly and country slapback at the short end of the range
- Medium echoes behind lead lines without a screen or menu
- Ambient and post-rock textures built from feedback rather than long repeats
Consider the trade-offs
When to look elsewhere
- Anyone needing repeats longer than 450 ms — that's the hard ceiling
- Players who want tap tempo, presets, or modulation on the delay
- Budget boards; $385 is flagship money for one time-based effect
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Delay Time, Feedback, Delay Level knobs only
You set repeat length, how many repeats, and how loud. Time is dialed by hand, not tapped in.
Detail 03
Single/Dual mode switch
Gives a second operating mode on the same pedal instead of one fixed delay behavior.
Detail 04
500 kΩ input impedance
High enough that it won't load down passive pickups, so it's safe to put early in the chain.
Detail 05
About 39 mA draw at 9V
Light current load — it will share a daisy chain or a small multi-output supply without trouble.
Detail 06
Residual noise −100 dB or less
Quiet enough that the noise floor isn't what stops you from dialing in heavy feedback.
Final check
Know before you order
- 01The AC adapter is sold separately — a 9V battery is the only bundled power option
- 02Battery life is roughly 2 hours on manganese, 8 on alkaline. Use a supply live
- 03Confirm 450 ms is long enough for your parts before committing at this price
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What's the longest delay time?
450 ms. The shortest is 20 ms, which is short enough for doubling and thickening. Anything past half a second is outside this pedal's range.
02Does it have tap tempo?
No. The controls are Delay Time, Feedback, and Delay Level, plus a Single/Dual mode switch and the effect footswitch. Delay time is set by knob.
03Can I run it on a battery?
Yes, one 9V (6LR61 or 6F22). Expect around 8 hours from an alkaline and about 2 from a manganese cell. The AC adapter is sold separately.
04Will it work on a daisy-chain power supply?
Yes. It runs at 9V and draws roughly 39 mA, which is a small share of any standard multi-output or daisy-chain supply.
