Hamilton-Kolby "Route 62" (BRN-6G2) Amplifier

The Hamilton-Kolby "Route 62" (BRN-6G2) Amplifier is a premium quality, hand-made mid-size combo amplifier built in the early 1960's brown-panel tradition. It's a replica of the 4-knob brown "Princeton" amp, from 1961-1963. Powered by a pair of 6V6GT power tubes, this combo amp delivers a classic sound, owing to its original 6G2 circuit with integrated bias-modulated tremolo.

  • finger-jointed pine cabinet,
  • vintage-style brown Tolex
  • 10" or 12" speaker,
  • 6G2 "Princeton" vacuum tube circuit

  • SwitchcraftTM jacks,
