Two-Rock Silver Sterling Signature 150/75W
Two-Rock · amplifier
The Two-Rock Silver Sterling Signature 150/75W Head runs four 6550 power tubes, the higher-output alternative to the 6L6-powered 100/50W version in the same Silver Sterling Signature line, and uses the same proprietary output transformer design to switch between 150 and 75 watts without tonal performance loss. The 6550 tubes give it a different harmonic character and higher maximum output than the 6L6 version, aimed at players wanting the most headroom and volume available in Two-Rock's flagship Silver Sterling Signature design.
