Soldano has re-released and updated the rack-mount version of the SLO-100 Head with the newly upgraded SLO-100R. Soldano’s Super Lead Overdrive 100 (SLO-100) set a standard for modern high-gain amplification. It all started in 1987, Mike Soldano built one of the first high-gain amp heads with searing harmonics and the ideal balance of gain, sustain and tight touch response. The new Soldano Super Lead Overdrive 100 delivers upon the “SLO’s” reputation in both appearance and performance but with the addition of some player-requested features. The SLO-100 continues to be hand-crafted in the U.S.
