The SURFING BEAR OVERDRIVE is an overdrive pedal that creates the most basic distortion required by guitarists of the present age. From clean boost to light crunch to bright and warm drive tones, this tone can be used freely for both rhythm and lead. This is a tone that is flat and has a wide dynamic range required for guitar tones, yet the mid tone is exciting. It can be used effectively not only by using it alone, but also by boosting other distortions and amplifiers with SURFING BEAR OVERDRIVE, or conversely pushing SURFING BEAR OVERDRIVE with another distortion or booster. The circuit is based on the legendary drive pedal "808". However, even if it is reproduced and reprinted as it is, it does not become the “current sound”. The tones demanded by today's guitarists have a wide dynamic range, good responsiveness with variable gain in the volume of the guitar, and clarity that makes it easy to understand the chord structure. However, it is not only clear, but the balance between attack and sustain is also important.
