Description

The Source Audio SA271 is a Zio Analog Front End + Boost was simple yet ambitious is an all-analog preamp boost pedal that includes a choice of four distinct preamp circuits, each with up to +20dB of additional output boost. ZIO is Source Audio’s first all-analog effects pedal and was designed in collaboration with Christopher Venter, the owner and sole engineer at SHOE Pedals.

JFET

This preamp mode is similar in character and behavior to a clean tube amp input with very low distortion. Using high-quality JFET Input Burr Brown OP Amps, this mode is transparent and will not add any harshness or excessive brightness. JFET mode is also very helpful in a studio or home recording environment for delivering a more natural sound to the DI or line inputs found on many pieces of studio equipment.

Low Cut

The LOW-CUT mode is designed to remove excessive low-frequency rumble and buildup that makes it more difficult to get guitars to sit well in a mix. The LOW-CUT preamp has no impact on the low midrange or presence frequencies, and, instead, reduces the low lows to improve headroom and provide a tighter sound. This is especially useful on guitar neck pickups, some basses, synths, and any other sound that may be too boomy and overpowering in a live or studio mix.

Studio

STUDIO mode is based on a pair of popular studios mixing tricks used on guitar and bass. It combines an EQ curve based on the famous Pultec Trick. This mode provides a low mid-cut to remove mud frequencies, a gentle presence boost in the upper midrange, and a natural-sounding high pass filter, to reduce low-frequency rumble.

E-Plex

This preamp mode is similar in character and behavior to a clean tube amp input with very low distortion. Using high-quality JFET Input Burr Brown OP Amps, this mode is transparent and will not add any harshness or excessive brightness. JFET mode is also very helpful in a studio or home recording environment for delivering a more natural sound to the DI or line inputs found on many pieces of studio equipment.
