Dr. J D57 Armor Buffer + Boost Pedal


In Stock

The Dr. J D57 Armor Buffer protects your signal degradation from long cable runs through your pedalboard. As your signal goes through more cable and pedals it subtly loses tone.

Do a simple experiment. Plug a guitar straight into your amp and play. Now plug that guitar into your pedalboard with all pedals off. If you A/B it, you'll notice some high end and volume loss due to the length of the cables. A buffer pedal solves this problem by working its magic electronic mojo to compensate for the loss of signal. The Armor Buffer does that, both at the beginning and end of your pedalboard to ensure your tone retains maximum awesomeness. Check out the video, where the demonstrator A/B's his signal with and without the buffer!

And if that wasn't enough it also acts as a boost pedal with maximum 20 db increase when boost is engaged. Value brothers, value.
