Designed for the guitarist who employs long cable runs, the TC Electronic BonaFide Buffer is designed to keep your tone pristine as it snakes through the forest of your guitar pedals. The BonaFide Buffer is a standalone, dedicated buffering solution that takes a high-impedance instrument signal—which is very susceptible to loading—and puts it through a buffer that outputs a low-impedance signal. This low-impedance, low-noise signal preserves your tone's critical high-end dynamics over long cable runs.
Some pedals have built-in buffers. However, those can be of inferior quality and can impart unwanted changes to your tone. If you're already plugged into the TC Electronic ecosystem of stompboxes, you'll note they all employ true bypass circuitry. The BonaFide, which is completely analog, sports a signal-to-noise ratio of less than >112 dB, and has a THD (Total Harmonic Distortion) rating of 0.001% THD, ensuring a low noise floor.
Another problem with most buffers is if the power goes, so does your signal. An intelligent bypass relay within the BonaFide will automatically disengage the buffer from the circuit in cases of a power loss, providing true bypass operation. Please note, the Bonafide Buffer requires a 9V, >100mA power supply to run.
