The Fredric Effects KC Buffer is a switchable dual buffer featuring the renowned buffer stage from the famous boutique overdrive pedal, and another transistor-based buffer popularised by an engineer/tech working with some of the world’s biggest touring bands. Buffers prevent treble loss caused by long cable runs and true bypass effects. Put it first in your effects chain and hear the difference. They're housed in custom enclosures especially fabricated for Fredric Effects and measure a diminutive 61 x 46 x 30mm - that's small! All parts are extremely high quality.
