The original 1x15 Vibroverb combo amps were only made for a short time. However, they were a big part of Stevie Ray Vaughan’s tone. Fender re-issued this model of the Vibroverb for a short period of time. When I heard that they were discontinuing it, I immediately bought the only one that I could still find. The re-issue incorporates several mods from Cesar Diaz, Stevie’s amp tech. It is way too loud for what I need and I almost never play it but it is a special amp for me…and I love it.
