The JAM Pedals Harmonious Fall is a limited-run multi pedal from the company's Custom Shop that unites two JAM favorites, the WaterFall and the Harmonious Monk, into a single, expressive tool. JAM describes it as delivering a richly textured modulation experience, from classic character to exploratory soundscapes, with harmonic tremolo, amplitude tremolo, chorus, and vibrato that move together or independently in a dynamic, musical interplay1.
What it does
The Harmonious Fall puts two modulation circuits in one box. The signal chain runs WaterFall → Effects Loop → Harmonious Monk, so the chorus-style circuit comes first and the tremolo circuit last1. JAM lists four effects across the pedal, which the maker says move together or independently1:
| Effect | Circuit side | What it covers |
|---|---|---|
| Harmonic tremolo | Harmonious Monk | Shapes different parts of the signal separately |
| Amplitude tremolo | Harmonious Monk | The classic volume-based tremolo effect |
| Chorus | WaterFall | The chorus-style circuit that leads the chain |
| Vibrato | WaterFall | Pitch-based modulation from the WaterFall side |
For players, that covers both the classic amplitude tremolo effect and harmonic tremolo, which shapes different parts of the signal separately, alongside chorus and vibrato from the WaterFall side1.
The effects loop and power
A practical feature for pedalboard users: the pedal is designed with a single power input and an integrated effects loop, allowing other pedals to be placed between the two circuits1. Anything patched into the loop sits between the WaterFall and the Harmonious Monk, so a drive, filter or other effect can be modulated by the tremolo circuit that follows it. One power input runs both circuits, so no second supply is needed for the Harmonious Fall itself1.
A limited run with hand-painted artwork
The Harmonious Fall is a limited-run pedal, and each enclosure carries hand-painted artwork. JAM states1:
"Every limited artwork pedal is a one-of-a-kind hand-painted piece."
The maker adds that the pedal you receive will differ in detail from the photos shown, so buyers should expect variation from one unit to the next1.
Because every unit is hand-painted and one of a kind, the artwork on the pedal you receive will differ in detail from product photos1.

JAM lists the Harmonious Fall at £478.00 regular price, with tax included1. The buying terms the maker gives are:
- 30-day money-back guarantee with a refund, no questions asked, for players who are not satisfied after receiving a product1

Questions
Which JAM pedals are combined in the Harmonious Fall?
The Harmonious Fall unites two JAM Pedals favorites, the WaterFall chorus and the Harmonious Monk, into a single pedal. The signal chain runs from the WaterFall circuit through an integrated effects loop and then into the Harmonious Monk circuit, so the two effects can work together in one enclosure.
Can I put other pedals between the two circuits of the Harmonious Fall?
Yes. The pedal is designed with a single power input and an integrated effects loop, which allows you to place other pedals between the two circuits. The signal chain is WaterFall, then the effects loop, then Harmonious Monk, so anything you patch into the loop sits between the chorus-style circuit and the tremolo circuit.
Is the JAM Harmonious Fall a limited edition?
Yes, it is a limited-run pedal from the JAM Pedals Custom Shop. Each one carries hand-painted artwork, and JAM describes every limited artwork pedal as a one-of-a-kind hand-painted piece, so the pedal a player receives will differ in detail from the photos shown on the product page.
Does the Harmonious Fall need one power supply or two?
One. The pedal is designed with a single power input, even though it contains two circuits. That single input powers both the WaterFall and Harmonious Monk sides, and the integrated effects loop lets other pedals run between them without needing a second supply for the Harmonious Fall itself.
Does the Harmonious Fall do vibrato as well as tremolo?
Yes. JAM lists the pedal's effects as harmonic tremolo, amplitude tremolo, chorus and vibrato, which the maker says move together or independently in a dynamic, musical interplay. That makes it a modulation tool covering both tremolo styles alongside chorus and vibrato in one enclosure.
