Rocktron's Boutique Series effects feature durable metal casings with laser etched artwork to create a rugged, eye-catching line of pedals. 

A more transparent overdrive amidst the heavier rock oriented Boutique series, the Valve Charger is designed to emulate the classic blues and rock tones of an overdrive tube amp. The Charger knob controls the gain, while a Tone knob rolls off the high end and a Level control adjust the output of the pedal.
