Coming this Fall and on a pre-order basis only: 

the JAM pedals Custom Shop Harmonious Fall unites two JAM pedals favorites into a single, expressive tool for players who chase tangible modulation and tone integrity.

Harmonic tremolo, amplitude tremolo, chorus, and vibrato move together or independently in a dynamic, musical interplay — delivering a richly textured modulation experience — from classic character to exploratory soundscapes.

Handcrafted for adventurous and purist musicians alike, this limited-run pedal is an open invitation to new undulating frontiers

Designed with a single power input and an integrated effects loop, it allows you to place other pedals between the two circuits, expanding both functionality and creative potential.
