SA 271 - ZIO Analog Front End + Boost
Source AudioProduct Description
The Source Audio ZIO is an all-analog preamp and boost pedal featuring four unique preamp circuits, each providing up to +20dB of output boost. Designed in collaboration with SHOE Pedals' Christopher Venter, the ZIO aims to enhance your tone and offers versatile placement within your signal chain, whether at the start for shaping your tone, post-drive for a clean boost, or at the end to restore signal quality over long cable runs.
Musically, the ZIO excels in providing clarity and warmth, while responding dynamically to your playing. Each of the four preamp circuits delivers specific tonal characteristics: JFET offers a transparent boost, LOW-CUT tightens the low end, STUDIO enhances clarity with mid-range focus, and E-PLEX adds subtle grit reminiscent of vintage tape delays. Additionally, the Tone toggle allows you to adjust capacitance for tonal shaping.
