The Moon Soup Ripple is a compact phaser pedal from JAM Pedals. It uses a two-stage phasing circuit with a single Speed control, and JAM Pedals describes the result as "a deep, soft-edged phase sound with a strong sense of movement and minimal tonal clutter." The pedal is priced at £264.00, and its dimensions, including jacks and controls, are 11.1 x 7 x 4.8 cm / 4.3 x 2.7 x 1.8 in.1
What it does to your sound
Two-stage phasing is the gentler end of the phaser family: fewer stages means a simpler, softer sweep than the deeper swirl of four- and six-stage designs. JAM Pedals describes the Ripple's compact two-stage circuit as producing a deep, soft-edged phase sound with a strong sense of movement and minimal tonal clutter.1
The single knob keeps operation simple:
- Speed sets the modulation rate, from slow movement to animated, quirky pulses.1
Where it sits on your board
JAM Pedals says the Ripple performs well before or after overdrive pedals, offering different levels of integration and prominence.1 In practice that means you can place it ahead of your drive pedals so the phasing gets pushed into the distortion, or after them so the sweep stays more distinct. Which position suits you depends on how prominent you want the effect to be.
Power is straightforward: a 9V battery or 9V DC, center-negative, drawing 9 mA.1 That low draw means it will run happily from any standard pedalboard supply output or a daisy chain alongside other compact pedals.
Artwork versions
JAM Pedals builds the Ripple in several custom artwork versions, all with the same sound and different artwork1:
- JAM Pedals Custom Ripple1
- JAM Pedals "Blue Dragon" Ripple1
- JAM Pedals "Concentric" Ripple1
- JAM Pedals "Achenbach" Ripple1
- JAM Pedals "Relic" Ripple1
Every limited artwork pedal is a one-of-a-kind hand-painted piece, so no two look alike.1
Guitarist Dweezil Zappa is named by JAM Pedals as a player using the Ripple.1
