Taming a screaming tube amp doesn't always require bulky and expensive load boxes and attenuators. If your amp has a series effects loop, the JHS Pedals Little Black Amp Box handles the job while fitting in the palm of your hand. Simply run it through your amp's effects loop and control how much signal you send to your amplifier's power section. You'll love how the Little Black Amp Box lets you really push the front of your amp for a natural feel and tone you can't get otherwise. And your bandmates, sound engineer, parents, neighbors, loved ones, and pets will love how it can keep your volume at bedroom levels.
