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.
