Colorado-based ToneVille amplifiers are built using 1/8″-thick aluminum chassis and cabinets of walnut and maple with dovetail joints.The company’s four amps – Rio Grande, Sunset Strip, Beale Street, and Broadway – all use NOS tubes and a circuit with a push/pull Master control, the ability to remove its EQ section from the circuit, a negative-feedback control, and the choice of a Jensen P12Q or Celestion G12H30 speaker. Output ranges from five to 15 watts, with the Rio Grande offering built-in reverb. The company’s outboard reverb unit is built to match its amps, and using the same construction materials and technique. Learn more at www.tonevilleamps.com.
