About this amp
The Silver Sterling Signature revisits and enhances Two-Rock’s original Sterling circuit on a newly designed silver anodized chassis. It’s offered in a 150/75W (6550) or 100/50W (6L6) power section, both power-scalable without tonal loss thanks to Two-Rock’s proprietary output transformer. A 7-position high/low filter, footswitchable FET boost and tone stack bypass, and a 6th 12AX7 cathode-follower tube for extra headroom and clarity round out the feature set, alongside tube-driven spring reverb. This model is sold as a head only, no combo version is offered.
