With the exception of the foot switch, this is all original. This is the craziest vibrato that I’ve ever heard a 10″speaker that screams when pushed. Supposedly a Supro or a Valco was Jimmy Page’s secret weapon in the studio. I hear Keith Richards loves these too.
The 16T is a three dial amplifier. One for vibrato and the other two for the guitar volume and tone. I had it checked out and it sounds as good as it originally was. Hard to believe these amps cost very little when they were released. You can use it as an input from a reamp device but why bother? You should just plug a guitar straight in with no pedals.
