rock. Pick up a Rocktron Valve Charger and let your inner bayou-bending,
rattlesnake crawling, voodoo res burn with tone that will send an armadillo
up a tree!

Control knobs for the Valve Charger include CHARGER, which controls the
amount of Overdrive desired. TONE controls the amount of highs. LEVEL
determines Output Volume. Simple, yet dangerous!
Want to drive your amp to a whole new level? The Valve Charger will make
your amp’s built-in distortion scream! Looking to add some edge to your
crunch tone? The Valve Charger will provide that much needed “bite” and
“growl” that will push the edge of the envelope!
Take your sound to new places and add the Valve Charger overdrive to your
setup. You’ll be glad you did.
The footswitch on the Valve Charger controls On/Off status (indicated by the
LED). This stomp box runs on a 9V Alkaline battery. You may also use the

bottom. Remove the back cover. Carefully remove the old battery and
replace it with a new 9V Alkaline battery. Replace battery in the same
area as the old battery was located. Place the back cover on the pedal and
re-insert the screws.
