I'm playing an amazing late 1950s early 1960s WEM Dominator MkI. This is the amp that Marshall copied for their 18W Baby Bluesbreaker (models 1974, 1973 and 1958). I'm playing it with a 1969 Gibson SG Special, 1973 Fender Stratocaster, 2008 Gibson Les Paul R9 and a 2021 Fender Telecaster CS 1960 Relic.
