Featuring gold-plated phase-reverse and ground-lift switches, this little red box was designed to eliminate hum thanks to its transformer-isolated signal paths.
These ABYs give players the option of choosing buffered or non-buffered modes for each channel, and feature nickel-core, custom-wound 1:1 transformers that do not boost treble frequencies.
