Get the sound and functionality of the GCB105Q without taking up much more space than a Phase 90! It's half the size and comes in a lightweight aluminium housing. Designed to retain and complement your low end with volume and Q controls to further fine-tune your Wah sound. Stepping in and out of the Wah effect is simple and seamless thanks to convenient auto-return switching and with such a small footprint, will fit nicely on your downsized travel board. Buffered bypass. Powered by 9 volt battery or AC adaptor (ECB003).
