The Jetter Red Square Overdrive brings together two of the company's most popular pedals in a single chassis with even more features in tow than ever. Pairing the fat, vintage SL tone of the Red Shift and the low-gain bluesy punch of the Helium, you get the same organic overdrive with the easily-tweaked knobs that made these pedals so popular. Throw in the voicing switch on the Red Shift side to completely alter the character of the overdrive for essentially three pedals in one.
