About this amp
The King Cobra takes the C-30’s power section and adds onboard spring reverb and tremolo plus a six-position rotary tone selector, all controlled through a single master volume with cut. Built around two EL34s, four 12AX7s, and an EF86, it’s a feature-dense single-channel amp sold factory-direct rather than through dealers.
