The WEEHBO Guitar Products GENKS Modulated Time Device is a delay pedal built around the PT2399 chip, voiced to sound like a classic analog delay. Pedal of the Day describes it as "our interpretation of a classic voiced and analog sounding delay," with a maximum delay time of 600 ms, tap tempo, switchable modulation and an oscillation mode for endless repeats1. Delicious Audio calls it "a modern, analolg-voiced digital delay with tap tempo, modulation and several other desirable features"2.
What it does to your sound
WEEHBO positions the GENKS as covering a wide range of delay duties. Pedal of the Day sums up the intended territory: "Whether you are looking for crisp slap-back echos, lush ambient delay lines with that extra kind of warble in the repeats or more classic, longer delays with fantastic bucket-brigade character"1. The repeats character is shaped by a toggle switch with three positions, choosing between bright, warm saturated or dark repeats1.
The modulation section adds movement to the repeats. It can be switched on or off, has separate rate and depth controls, offers three waveforms (sine, triangular and rectangular) and runs at a modulation speed of 1 to 10 Hz1.
Controls
| Control | What it does |
|---|---|
| Time knob | Sets the delay time manually2 |
| Repeats toggle switch | Chooses between bright, warm saturated or dark repeats1 |
| Modulation section | On/off switchable, with separate rate and depth controls, three waveforms (sine, triangular, rectangular) and a modulation speed of 1 to 10 Hz1 |
| Rate knob | Sets the modulation speed2 |
| Depth knob | Activates the modulation section when turned up2 |
| Tap Tempo footswitch | Tap tempo with 4th, 8th and dotted 8th division modes12 |
Tap tempo and oscillation
The Tap Tempo footswitch does more than set the time. Tapping sets the delay in one of three division modes, and holding it produces a momentary self-oscillation effect, in Delicious Audio's description2. Pedal of the Day adds that a long press on the tap button engages a dedicated oscillation mode with endless repeats1, a feature experimental players often look for in a delay.
The bypass is configurable: the GENKS offers buffered bypass with trails, or true bypass using a relay system and soft switch1. Which behavior you get depends on the option chosen, so it is worth knowing which version you are plugging in.
Built on the PT2399
The delay circuit is based on the PT2399, a chip Pedal of the Day calls "the well-known and iconic PT2399 chip"1. The PT2399 is an echo processor widely used in delay designs; GuitarPCB, which sells the chip for its own NostalgiTone Space Modulator and D'Lay PCBs, calls it "the best chip" for those projects3. In the GENKS, WEEHBO pairs the chip with an all-analog dry signal path1, and Pedal of the Day credits the result to filtering and processing: "Thanks to careful filtering and signal processing we managed to create an authentic delay pedal with a unique touch"1.
What reviewers said
Pedal of the Day's 2024 review is the main published verdict. Its reviewer found the pedal flexible across gain and texture: "The GENKS Modulated Time Device can be clean, dirty and everything in between, loaded with features and packed with experimental options"1. The same review highlights the oscillation mode, the three-position repeats switch and the modulation section as the features that set it apart1.

Questions
Is the WEEHBO GENKS analog or digital?
Delicious Audio describes the GENKS as a modern, analog-voiced digital delay. Pedal of the Day notes that the delay circuit is based on the PT2399 chip and that the dry signal path is all analog. In practice it is a digital delay chip voiced and filtered to sit close to older analog-sounding designs, rather than a true bucket-brigade analog circuit.
How long is the maximum delay time on the GENKS?
The maximum delay time is 600 ms. Both Pedal of the Day and Delicious Audio give the same figure, with Delicious Audio noting the Genks can deliver repeats as long as 600 ms. That range covers slap-back and shorter rhythm echoes comfortably, while longer ambient lines sit at the top of the control's travel.
Does the GENKS have tap tempo?
Yes. The GENKS has tap tempo with three division modes: quarter notes, eighth notes and dotted eighths, selected from the Tap Tempo footswitch. Holding the same footswitch produces a momentary self-oscillation effect, and a long press engages an oscillation mode with endless repeats.
Does the GENKS have true bypass or trails?
Both, as an option. Pedal of the Day lists the GENKS as offering buffered bypass with trails or true bypass with a relay system and soft switch, so the player can choose how the pedal behaves when it is switched off.
How do you get endless repeats on the GENKS?
Engage oscillation mode by long-pressing the tap button, per Pedal of the Day. Delicious Audio adds that simply holding the Tap Tempo button produces a momentary self-oscillation effect, so the repeats build on themselves for as long as the switch is held.
Where is the GENKS made?
Pedal of the Day states the GENKS is designed, engineered and hand built in Germany by WEEHBO Guitar Products.
