The "Concentric" Ripple is a phaser pedal from JAM Pedals, the Athens-based builder. It uses a two-stage phasing circuit with a single Speed control, and JAM describes the result as "a deep, soft-edged phase sound with a strong sense of movement and minimal tonal clutter"1. The pedal is sold in limited artwork versions, each a one-of-a-kind hand-painted piece1.
Controls
The Ripple keeps things to one knob:
| Control | What it does |
|---|---|
| Speed | Sets the modulation rate, from slow movement to animated, quirky pulses1 |
A single-knob layout means there is no depth or feedback control to set: the character of the phase is fixed, and Speed shapes how quickly it moves. Players who want more control over the phase sweep may want to compare it with the standard JAM Pedals Ripple or the Custom Ripple1.
Power and connections
The Ripple runs on a 9V battery or a 9V DC center-negative supply and draws 9 mA1. That is a light load by pedalboard standards, so it can share a supply output with other low-draw pedals without trouble. Bypass is true bypass, so the phasing circuit is out of the signal path when the pedal is off1.
Placement with overdrive
JAM Pedals addresses the before-or-after question directly: "The Ripple performs well before or after overdrive pedals, offering different levels of integration and prominence"1. In practice, that means a player can experiment with both positions on the board: before overdrive or distortion the phase sweep is what the drive circuit then shapes, while after it, the sweep acts on the driven tone itself.
Artwork versions and availability
The "Concentric" Ripple is offered as a limited artwork pedal, and JAM states that "Every limited artwork pedal is a one-of-a-kind hand-painted piece"1. Custom artwork versions include:
