Drawing inspiration from the coveted Univox UD-50 Uni-Drive, famously employed by musical legends such as Hendrix and Jimmy Page during the late '60s and early '70s, Danelectro presents "The Breakdown." This pedal utilizes three 2N3904 silicon transistors, replacing the original and now out-of-production silicon Matsushita 2SC859 "black button" transistors. With a staggering 35 dB of gain, it unleashes a powerful assault on your amplifier's front end. Keeping things straightforward, the controls consist of a volume knob and a 6-position "break-up" knob.
