Source Audio ZIO Analog Front End + BoostProduct Details: The word "ZIO" is an acronym for Impedance (?Z'' is the electrical symbol for impedance), Input (?I''), and Output (?O''). The pedal is designed to take a guitar's high impedance signal, sweeten the tone with any of its four preamp circuits, and output a strong, low impedance signal that won't be altered by the buffered dry tones of effect pedals further down the signal chain. High fidelity, noise-free Burr-Brown op amps help give ZIO extreme clarity and responsive pick dynamics, while maintaining ideal body and warmth. ZIO has four distinct preamp circuits. JFET offers a completely transparent signal boost with zero coloring or distortion. LOW-CUT reduces ?tubby'' bottom-end for a tighter sound with added headroom. STUDIO finds inspiration from the time-honored ?Pultec Trick,'' a studio technique that adds clarity by cutting the ?mud frequencies'' and adding mid-range articulation. E-PLEX captures the focused and subtle grit of the preamps found in vintage Echoplex Tape Delay units. The ZIO's simple control set makes it easy to find the perfect ?base tone'' for any guitar and ensures that the dry signal hitting each pedal and the amplifier remains strong and consistent. The ZIO's TONE toggle offers three different levels of capacitance (or simulated cable length) to brighten or darken the tone.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. Due to its design, JFET mode can also interface with lower impedance line inputs without excessive loss of bass content.When we connect a cable to the output of a passive guitar pickup, it does more than just pass signal on to the next device. Many guitarists will be familiar with the idea of different cables imparting a specific tonal quality. This is because cables have a property called capacitance, which increases with the length of the cable. This capacitance interacts with passive pickups and guitar wiring, to create a resonant filter and the higher the capacitance of the cable, the lower the cut-off of the resonant frequency. The three toggle positions replicate different lengths of cable. Select the BRIGHT position to introduce a low capacitive load and the most treble content. Selecting MED provides additional capacitance and produces the effect of a medium length of cable (roughly 15 feet). Selecting the DARK mode gives the effect of a longer cable or coils cable and is useful for taming excessive brightness or providing a stylistic voicing choiceAfter bench-testing some classic op-amps used in overdrive, distortion, and boost stompboxes such as the ubiquitous TL072 and about half a dozen popular op-amp chips spanning back to the 1970s, we selected the Burr Brown for its pure tonality, dynamic range, frequency response, and overall feel. While other chips had certain properties such as sounding "too bright", "too thin", "too distorted", etc., the unmatched transparency and headroom of this 14-legged Burr Brown OPA chip was the perfect match for the ZIO's mission of delivering you your own tone, but better.
