The Polarbear Effects Gardelyn is a PT2399-based dual parallel delay with three independent tremolo points, released in late 2025. Each tremolo point sits in series with the delay and can be set to Off, On, Blinking, Fading, or Blinking + Fading, producing what Guitar Pedal X's Stefan Karlsson described as "a fluttery dual/triple tremolo delay"1. In the site's year-end roundup of new delay and reverb pedals it appeared as the "Gardelyn PT2399 Dual Parallel Delay with 3 Tremolo Points"2.
Controls and footswitches
The three tremolo points are each set by a push-button with five modes, and four LEDs show the tremolo pattern as it hits across those three points1.
| Control | What it does |
|---|---|
| Tremolo Points 1-3 push-buttons | Off, On, Blinking, Fading, or Blinking + Fading for each point2 |
| Left footswitch | Delay On/Off / Engage1 |
| Right footswitch | Triggers a new Tremolo Seed / Sequence1 |
| LEDs (four) | Show the tremolo pattern across the 3 tremolo points1 |
The right footswitch is the part that makes the tremolo playable in the moment: rather than a fixed pattern, a tap reseeds the sequence, so the way the tremolo falls across the delay repeats can be changed mid-performance1.
Enclosure and price
The Gardelyn sits in a vertical mid-sized 1590BB enclosure, which Karlsson noted is less compact than earlier Polarbear formats and takes up more pedalboard real estate1. It was reported as "well-priced at €219 on the Polarbear Effects Webstore" at launch1, and the year-end roundup listed it at €219 / $255 EUR and USD2.
What reviewers said
Guitar Pedal X included the Gardelyn in its 2025 roundup of new delay and reverb pedals, where Karlsson wrote:
"This new Gardelyn pedal is pretty unique and sounds fantastic!"
The same roundup described Polarbear as making exceptional use of the PT2399 chip and called Darko the master of the PT2399 chip overall2. The earlier news piece, while positive on the circuit, was a little sad that the compact enclosure format had seemingly been abandoned in favor of the larger vertical 1590BB1.
Polarbear Effects has built a number of pedals around the PT2399, including the Raposa and Young Hearts, and the Gardelyn sits in the delay side of the range with tremolo built in, a combination also explored on the site's tremolo page1.

Questions
What chip does the Polarbear Gardelyn use?
The Gardelyn is built around the PT2399 chip. Guitar Pedal X describes Polarbear Effects as making exceptional use of the PT2399 in this design, running a dual parallel delay arrangement and adding serial tremolo points into the mix. The maker has built a number of pedals around this chip, and one reviewer called Darko the master of the PT2399 chip overall.
What do the three tremolo points do on the Gardelyn?
Each of the three tremolo points is set with its own push-button and offers five modes: Off, On, Blinking, Fading, or Blinking + Fading. The points work in series with the delay, and four LEDs show the tremolo pattern as it hits across the three points, creating what Guitar Pedal X called a fluttery dual/triple tremolo delay.
What does the right footswitch on the Gardelyn do?
The right footswitch triggers a new Tremolo Seed or Sequence, changing the tremolo pattern on the fly. The left footswitch is the Delay On/Off or Engage switch, so the two switches split duties between turning the delay on and off and reshaping the tremolo.
How much does the Polarbear Gardelyn cost?
Guitar Pedal X listed the Gardelyn at €219 on the Polarbear Effects webstore, and in its year-end delay and reverb roundup gave the price as €219 / $255 EUR and USD. The writer described it as well-priced at the webstore figure.
What size is the Gardelyn enclosure?
The Gardelyn uses a vertical mid-sized 1590BB format enclosure. Guitar Pedal X noted it is less compact than earlier Polarbear formats and takes up more pedalboard real estate, though the writer still called the pedal pretty unique and sounds fantastic.
