Custom Shop! - This amp started life as a V-Plex 25 watter. It was then converted to 50 watt specs, we installed the V-Rock circuitry in addition to adding a 2nd 'Gain' control & our 'Global' control for added versatility. This amp is equipped with 12AX7's & EL34's & Mercury Magnetics Transformers. Feel free to share the photo!
