This buffer box was developed in collaboration with CAE. Its adjustable setting of 0dB to +6dB allows you to adjust the signal level to suit your environment. It also helps prevent deterioration caused by cable routing and reduces on/off noise caused by the passive true bypass switch.・It's a low-noise buffer in a small, rugged housing;・it can add up to +6dB of gain with the front-facing gain slider;・it makes up for signal loss that can occur when combining effects with different impedence levels;・it fine-tunes signal recovery with Hi and Lo cut switches;・it has an extra output for a tuner, separate effects chain or amp, and can be set to receive either a buffered or unbuffered signal;・It also features a convenient 9VDC power output jack provides power for another pedal. Approximately W63 x D72 x H27 mm (excluding protrusions) *The slide lever has a center click feature, but there does not appear to be any particular purpose for this.
