The Mosky DEC Buffer Booster is a compact pedal that does two jobs with one knob: it works as a clean buffer and as a clean boost. With the volume knob at zero it acts as a clean buffer, and turned above zero it becomes a clean boost, raising your signal without changing its character. Mosky lists it with true bypass switching and a single knob for control.1
What it is based on
Mosky's product page states that the DEC Buffer Booster is "Based on Wampler decibel + Buffer/Boost pedal."1 That design pairs a buffer with a boost in one enclosure, which is what the DEC does: the buffer protects your signal, and the boost pushes it when you need more level. If you want a similar idea in a different form, Mosky also makes the Mosky Dec Mini, and other boost options in the range include the Mosky SHO BOOSTER and the Mosky BP Booster. For more on the effect type itself, see Buffer Pedals and Boost Pedals.
The volume knob: buffer at zero, boost above it
The DEC's only control is its volume knob, and Mosky describes its two positions simply: "volume=0 :clean buffer"1. In practice that means:
- Knob at zero: the pedal works as a clean buffer.
- Knob above zero: the pedal works as a clean boost.
A buffer's job is to keep your guitar's high end intact over long cable runs and crowded pedalboards, and the DEC's 1M ohm input impedance and 1k ohm output impedance are the figures that matter for that job.1
Power and hooking it up
Mosky specifies a 9VDC AC adapter with negative tips, regulated recommended, and describes the adapter as optional.1 No current draw figure is given.
Mosky's page lists an AC adapter as the power source and does not mention a battery compartment, so plan on a 9V DC center negative supply.

Questions
What is the Mosky DEC Buffer Booster based on?
Mosky's product page states that the DEC Buffer Booster is based on the Wampler decibel + Buffer/Boost pedal. It follows the same basic idea: a single volume knob that takes the pedal from clean buffer to clean boost, with true bypass switching and a 1M ohm input impedance.
Is the Mosky DEC Buffer Booster true bypass?
Yes. Mosky lists the DEC Buffer Booster with true bypass switching, so when the pedal is off your guitar signal passes straight through without going through the buffer circuit.
What does the volume knob do at zero?
With the volume knob at zero the DEC acts as a clean buffer. Turn the knob above zero and it becomes a clean boost, raising your signal level without adding distortion. One knob covers both jobs.
What is the input impedance of the Mosky DEC?
Mosky specifies a 1M ohm input impedance and a 1k ohm output impedance. A high input impedance like that is typical of a buffer, designed to keep your guitar's tone intact.
Does the Mosky DEC Buffer Booster take a battery?
Mosky's page lists power as a 9VDC AC adapter with negative tips, regulated recommended, and describes the adapter as optional. No battery compartment is mentioned, so plan on using a 9V DC supply.
