Head: 1 Knob is Missing!

RM100LB

Back for the attack in 2009, The MTS Lynch Box Series now includes the 2-channel, 50 watt RM50HLB MTS head. Each Lynch Box head is based around the standard RM100 and RM50 models with custom alligator cosmetics and tweaks to meet George's tonal needs. Each LB model is loaded with EL34 power tubes for that classic hard rock tone and thick bottom end. Simply choose and load any combination of Lynch's four custom tube preamps into your choice of 100 watt Lynch Box head or newer 50 watt Lynch Box head and combo. If four tones aren't enough for you, choose any of the available tube preamp modules.
