Built as a collaborative effort between Andy Timmons and JHS, JHS's The AT is Timmons' signature drive pedal, tweaking and adding to one of the guitarist's favorite drive pedals: the JHS Angry Charlie. Four knobs for volume, EQ, drive, and "Air," which functions as a low-pass filter, give you control over your signal, and the three-way toggle handles headroom, giving you the choice between 25w, 50w, or 100w modes. If you want some classic British tones akin to those of the Marshall JCM800, the AT Andy Timmons Signature Drive by JHS is a great start.
