Analog Front End and Boost!

The Source Audio ZIO is built to, in the company’s own words, "make everything sound better".

In other words, it's much more than just a simple boost pedal!

Featuring an all-analog design, ZIO boasts four distinct preamp circuits to take your tones to the next level.

ZIO is a deceptively flexible unit that can serve many different purposes at various places in your signal path.

Whether it’s boosting your combo into low breakup or trimming the fat off a thrashing high-gain head, ZIO delivers!

Boost pedals can sometimes come across as one-dimensional, but the power and versatility of ZIO truly set it apart from the rest of its 1-knob brethren.

ZIO’s intuitive controls make it easy to dial-in any sound: Output, Circuit, Tone, and Switch are the only functions you’ll have to worry about.

Four distinct preamp circuits!

ZIO serves up a quartet of unique preamp circuits to perfectly dial-in your sound:

JFET : Designed to function transparently, the JFET boosts without adding in any unpleasant harsh qualities.

Low-cut : This mode strictly impacts the low end with no changes to the low midrange. Works great to improve headroom and clean up your mix.

Studio : This mode takes inspiration from the famous “Pultec trick” of the 1950s to provide greater clarity to your sound.

E-Plex : Modeled on the famous '70s Tape Echo. Provides a slightly dirty, midrange-focused boost that is dripping with analog character.
