The Supro Reverb is a classic mid-range Valco combo featuring onboard spring reverb alongside the raw American tube tone the Supro brand is known for. The reverb circuit produces a lush, slightly lo-fi character that complements the amp's natural harmonic richness perfectly. This model was popular for both stage and studio work during the mid-1960s.
