Lab Series L5
Lab Series · amplifier
The Lab Series L5 is a solid-state combo amplifier from the 1970s developed by Norlin, Gibson's parent company at the time, with engineering input from Moog, giving it circuitry unusual for a guitar amp of its era and an unmistakable, extremely clean, high-headroom character on its normal channel alongside a distinctly aggressive, saturated overdrive mode. It became a cult favorite among jazz, blues, and funk players for that pristine clean headroom, while also finding an unlikely following among early metal and hard rock guitarists drawn to its surprisingly heavy, thick distortion channel. Players including Mike Stern and John Scofield have long relied on the L5 for its clean tone, while Kirk Hammett famously used one in Metallica's earliest years.
