A One-Stop Solution that addresses both Input and Output Challenges
The HIGH-WIRE™ DUAL BUFFER/OUTPUT BOOST resolves the deep-rooted signal loss and inconsistent tone issues faced by guitarists due to; capacitive loading, impedance loading and mismatching, and changes to a pickup’s resonant frequency/peak, as a result of varying effect pedals and interconnecting cables. It accomplishes this by providing the two constants in every guitar rig, the guitar and amplifier, with a resolute load and source, via its input buffer and output line-driver, respectively. The two circuits form an effects loop, which segregates the guitar and amplifier from the variables on a pedalboard, easily handles many pedals, interconnecting cables and effortlessly drives a long cable run to the back-line amplifier. The input buffer converts the guitar’s high-impedance signal to low-impedance, which also minimizes its susceptibility to noise, interference and even some of the switch “popping” associated with true-bypass pedals. The output line-driver targets the inability that many pedals (and even some buffers have) which is to adequately drive a very long cable run to a back-line amplifier. As a result, the only variations in sound and tone will be from the actual effect of the pedals on the pedalboard, and not from a guitar or amplifier related loading or impedance mismatch issue.
The input buffer is a 100% discrete Class-A circuit with an input impedance and other finely tuned characteristics which mimic that of a high quality tube amplifier, and it includes an RFI filter to minimize the possibility of radio-frequency interference and noise. It presents a dynamically ideal load to a guitar that remains steadfast, resulting in a tone that is consistent, while still allowing the guitar to breathe, live, and react - like plugging directly into the front of a tube amplifier.
The integrated output line-driver circuit is capable of driving a long unbalanced cable run, via shielded 1/4” TS instrument cable. It also incorporates a mini-toggle fixed boost and a stomp-switch selected variable boost, to slightly increase the level reaching a back-line amplifier (making up for any losses or compensating for different guitars), and to drive the amp’s input harder!
A dual-function STOMP switch allows selecting the variable BOOST, or a MUTE for silent tuning and guitar changes. To activate the variable boost, as set by the BOOST knob, simply press the STOMP switch, a blue BOOST LED indicate’s when it’s on. Press the STOMP switch again to turn it off. To activate the MUTE, hold down the STOMP switch for about 3/4-of-a second, a red MUTE LED indicate’s it’s on. Press the STOMP switch again to exit the MUTE mode, and the HIGH-WIRE™ DUAL BUFFER/OUTPUT BOOST will return to on or off BOOST state it was in, prior to activating the MUTE. The HIGH-WIRE™ DUAL BUFFER/OUTPUT BOOST’s strategic first-in last-out position in the audio signal path also allows it to provide a compact and convenient consolidation point for the two most commonly used pedalboard audio connections. And thanks to its dual-PCB analog-goodness design, it will stand tall at the “typical” top-right corner of a pedalboard - without the need for a pedal-riser.
