NostalgiTone Dual Combos pair two carefully selected Singles inspired by a particular era, genre, artist, or iconic guitar sound. Every Dual Combo features our Dual Combo Creator PCB with Order Switching, allowing you to change the signal path and discover how the two effects interact in different ways. Designed to capture the character of classic tones while giving you the freedom to create combinations of your own, each Dual Combo brings two distinct pieces of guitar history together in one unique, buildable package
