The Weehbo Genks Modulated Time Device is a delay pedal from WEEHBO Guitar Products, a company Delicious Audio describes as best known for their Plexi-style overdrive. The Genks is a modulated delay: a digitally processed but analog-voiced delay circuit built around the PT2399 chip, with an all analog dry signal path, tap tempo with subdivisions, switchable modulation, and a self-oscillation mode hidden under the tap switch12.
An analog-voiced delay with modulation
Weehbo describes the Genks as "our interpretation of a classic voiced and analog sounding delay." The delay circuit is based on the PT2399 chip, an IC that turns up in a large share of delay pedals, and the company says careful filtering and signal processing were used to get an authentic delay sound with a unique touch2. Delicious Audio's Paolo De Gregorio called it "a modern, analolg-voiced digital delay with tap tempo, modulation and several other desirable features"1.
Because the dry signal runs through an all analog circuit, the repeats are what the digital processing shapes. Weehbo says the pedal covers "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"2. The Pedal of the Day review summed it up as a pedal that "can be clean, dirty and everything in between, loaded with features and packed with experimental options"2.
The maximum delay time is 600 ms, set either manually with the Time knob or by tapping in a rate12.
The controls
The Genks keeps its front panel fairly simple: three knobs (Time, Rate and Depth) and three toggle switches (LFO shape, Div and Tone), plus the Tap Tempo footswitch1.
| Control | What it does |
|---|---|
| Time | Sets the delay time manually1 |
| Rate | Sets the modulation speed1 |
| Depth | Activates the modulation section when turned up1 |
| Tone toggle | Three EQ voices for the repeats: Bright, Warm/Saturated or Dark12 |
| Div toggle | Three tap subdivisions: 4th, 8th and dotted 8th1 |
| LFO shape toggle | Selects one of 3 LFO shapes1 |
| Tap Tempo footswitch | Taps the delay time; held, it produces self-oscillation12 |
The modulation section is switched on and off by the Depth knob, with separate rate and depth controls and three waveforms: sine, triangular and rectangular2. On modulation speed, the two published accounts disagree: Pedal of the Day gives a range of 1 to 10 Hz2, while Delicious Audio states the speed goes "from speed 1 Hz to 10 kHz"1. Both figures are given here as stated.
Tap tempo and self-oscillation
The Tap Tempo footswitch does double duty. Tapped normally, it sets the delay time, with the Div toggle choosing between quarter, eighth and dotted eighth divisions12. Held down, it produces a momentary self-oscillation effect, and a long press engages oscillation mode with endless repeats12. That makes the pedal usable both as a straightforward timed delay and as an experimental tool for building runaway feedback on the fly.

Questions
What chip does the Weehbo Genks use?
The delay circuit is based on the PT2399 chip, a delay IC widely used in pedal design. Weehbo describes the Genks as a classic voiced, analog sounding delay built around that chip, with careful filtering and signal processing used to shape the repeats. The dry signal path is all analog, so the guitar's untouched tone passes through an analog circuit while only the repeats are processed digitally.
How long is the maximum delay time on the Weehbo Genks?
The maximum delay time is 600 ms. Delay time can be set manually with the Time knob, or tapped in with the Tap Tempo footswitch. Within that window Weehbo says the pedal covers crisp slap-back echoes, ambient delay lines with warble in the repeats, and longer, more classic delays with bucket-brigade character.
Does the Weehbo Genks have tap tempo?
Yes. The Genks has a dedicated Tap Tempo footswitch with three division modes: quarter notes, eighth notes and dotted eighth notes, selected with the Div toggle switch. Holding the same tap button engages oscillation mode, which produces endless repeats, or a momentary self-oscillation effect when held briefly.
How do you get self-oscillation on the Weehbo Genks?
Press and hold the Tap Tempo button. Holding it produces a momentary self-oscillation effect, and a long press engages oscillation mode with endless repeats. It is a hands-on way to build a swelling wall of feedback on the fly and then return to normal repeats when the button is released.
Is the dry signal analog on the Weehbo Genks?
Yes. Weehbo states that the dry signal path is an all analog circuit, while the delay circuit itself is a digitally processed, analog voiced design based on the PT2399 chip. That arrangement keeps the untouched guitar tone in the analog domain and reserves the digital processing for the repeats.
