Soldano SLO-100
The SLO-100 (short for Super Lead Overdrive 100) is a guitar amplifier designed by Mike Soldano and the first production model from his company Soldano Custom Amplification. Released in 1987, the SLO-100 was hand-built and pushed the boundaries of high-gain guitar tone during an era of mass-produced amps that were insufficient for increasingly heavy music without modifications. Hard rock and metal guitarists like Eddie Van Halen, George Lynch, and Mick Mars helped popularize the SLO-100 and its high-gain sound, while the amp's clean and lower-gain tones attracted players like Eric Clapton, Mark Knopfler, and Warren Haynes. The SLO-100 is considered one of the industry's benchmark amps and helped establish the boutique amplifier market.
