The Mosky Audio DEC Buffer/Booster is based on the Wampler Decibel + Boost/Buffer.
The DEC buffer can either be used as a buffer to reduce the impedance of your guitar signal or as a clean boost.
Having a too long cable or too many cables to/from your pedal board and amplifier can suck tone out of your signal. Higher frequencies can get lost, leaving your guitar tone muddy. A good buffer pedal will help to prevent this tone sucking from occurring. The DEC booster not only works as a buffer for this purpose, but can also be used to boost your signal to hit the front end of your amplifier harder.
The DEC booster features true bypass switching and a fully analogue signal path
