The Silver Sterling Signature continues the pursuit of iconic guitar tones. Built on the newly designed silver anodize chassis, this amp delivers a solid platform that immediately proves why Two-Rock is known for delivering products built for the serious artist.

After nearly a decade of R&D since the original Sterling was released and a lifetime of listening to the iconic guitar tones this coveted amplifier has produced, Two-Rock has revisited this classic circuit.  The 100 watt version is switchable to 50  using Two-Rock’s proprietary output transformer design that allows zero performance loss when power scaling. There’s no doubt that this amp loves to be pushed to the limit, so the tone stack and the filter switches allow the user plenty of flexibility to find the right tone. 6 12AX7’s gives this amp a lush reverb and a cathode follower tube that extends the punch of this amp and adds an immediacy to the feel as well as headroom and clarity.
