Coral Adder

There's nothing like the "wall of tone" you get from a great, high gain British rock amp. From classic 70's crunch to the singing, violin-like leads of the 80's to the sludge and mass of cranked up amps in the 90's, the Coral Adder brings it all to your pedalboard. Designed to replace a gained out tube amp, the Coral Adder is your custom rock tone in a to-go box. If you have multiple amps but want the same crunch every time or if you are on the road and have to use back-line amps, the Coral Adder will take over and give you exactly what you need. 

With its 3 band EQ, you can dial the Coral Adder™ in to create endless versions of a classic British crunch tone. Also, the Coral Adder's™ "Venom" volume knob works as an overall volume for your tone. This way, if you have a small tube amp that just doesn't get quiet in a small room, you can back the "Venom" off and get a practice level crunch that won't wake the kids without losing your tone. With the Coral Adder™ you can turn any amp into the ultimate, low volume practice amp 

All Tortuga pedals can be special ordered with custom graphics at a $30 up-charge. If you have an idea for a custom look, just let me know.
