Alex Lifeson and Mojotone joined forces back in 2012 to produce the first Lerxst amplifier – the limited edition 25/50-watt OMEGA head – based on the Marshall Silver Jubilee guitar amps that Lifeson used during the recording and touring cycles for Rush’s Clockwork Angels album but featuring several circuit modifications, parts upgrades and hand-wired construction. 

The 15-watt 6V6-driven Lerxst CHI combo followed shortly afterwards in 2015, offering a more affordable, lower-powered variation of the OMEGA.
