The Silver Sterling Signature 100 Head is Two-Rock's take on the original Sterling, revisited after nearly a decade of work: four 6L6s for 100 watts, switchable to 50, a tone stack with high and low cut filters, all-tube spring reverb and a sixth 12AX7 as a cathode follower for punch and headroom.
The FET and the tone stack bypass are both on the footswitch, and the 7-position High and Low filters let you trim the top and the bottom to suit the room and the guitar. Two-Rock's own output transformer means the tone and feel hold up when you drop to half power. It's built on a silver anodized chassis in the wider SSS cabinet.
The 150 is the same amp on 6550s with more headroom; the 100 is lighter and the one most players will want. Pair it with the 2x12 SSS Width cabinet, made to match its width. The standard build is in black bronco with black matrix cloth.
The photo shows a Silver Sterling Signature head in grey suede on a 2x12 cabinet, as an example. The cabinet is sold separately. Other coverings and grille cloths are available to order, and the price changes with the options chosen.
