SOURCE AUDIO / SA271

A buffer/booster pedal with four selectable types of tone nuance.

A treatment box that answers ""Just a little more...""
Source Audio ZIO is the first analog product released by a group of cutting-edge digital engineers originating from Kurzweil, a long-established synthesizer manufacturer.

You can choose from four types of tone nuances: ""JFET"", which uses the same Burr Brown op-amps used in the buffer circuit of the legendary sound system CUSTOM AUDIO ELECTRONICS 4×4, ""LOW-CUT"", which cuts out stagnant low tones, ""STUDIO"", which gives the sound a sense of transparency, and ""E-PLEX"", which uses a tape echo preamp that is favored by many top musicians.

Answering those ""just a little more"" and ""just a little bit more"" that only players who care about sound can understand. This is a treatment box for subtle but important sounds.

Best-in-class Burr-Brown op-amps
Classic TL072 and After testing several well-known models used in overdrive, distortion and boost pedals, including op-amps from the 1970s, other op-amp chips were too bright, too thin, too distorted, etc.

The 14-pin Burr-Brown OPA chip was chosen for its pure and transparent tone, wide dynamic range, frequency response and overall feel, which allows ZIO to achieve its mission of ""Make Everything Sound Better!""

4 types of preamp models x 3 types of cable capacitance
The CIRCUIT selector knob (4 directions) determines the preamp model that will be the axis of the sound. Then, the TONE toggle switch (3-way) adjusts the difference in sound depending on the length of the cable wiring. By combining these, we create the overall sound of ZIO.
