I just dropped a mule in a LP Custom and it is as advertised-balanced in the eq, it adds a nice bite that my Custom had been lacking-not compressed sounding...great percussive nature..very dynamic-is equally at home doing Allmans or Tool(as a matter of fact, after some dropped d and a healthy dose of Mesa, it is as close as I have ever come to mr Adam Jones's tone-lots of clarity/headroom-strong and tight...big and bite-y!!)an all 'rounder!
