Two-Rock builds some truly amazing tube amps. They have a custom speaker built by WGS. The 12-65B was built to Two-Rock specs and is only available directly from them. Some of Two-Rock's artists include John Mayer, Eric Gales, Matt Schofield, & Brad Whitford.
Suhr has a facility with state of the art equipment combined with old world style craftsman to make some of the best guitars and amps available.
Bob Reinhardt is an amazing builder with a real knack for tone. We've followed his keen ear and developed a few custom speakers for him. They are available only through Reinhardt amps and include his versions of the 65 and 30 style speakers.
There's a shout-out to WGS around 2:20 in the video. Thanks Bob.
