Suhr SL-15
Suhr · amplifier
The Suhr SL-15 is a boutique 15-watt all-valve head voiced after the classic British plexi Super Lead, delivering open, dynamic cleans and a thick, harmonically rich plexi-style overdrive at lower, more usable volumes than a full plexi. Hand-built by Suhr, it captures vintage Marshall flavor with modern refinement for classic rock and blues-rock players.
