The SB-15 is an ultra-compact signal buffer that is pedalboard friendly, with transparent operation that maintains the natural tone of your instrument. Unlike many audio designs that employ ICs or integrated circuits to buffer the signal, the 100% discrete class-A design of the SB-15 reduces the need for phase-cancelling negative feedback produces a more natural and pleasing tone. This is complimented by a Drag control load correction circuit to replicate the tone and feel as if connected directly to the amplifier. Once buffered, the signal is less susceptible to hum and buzz caused by radio interference and electromagnetic fields, and is then able to drive multiple pedals distances of 15 meters (50') without noise.
