The Hamilton-Kolby Pro-15 Amplifier is a premium quality, hand-made combo amplifier built in the
50's tweed tradition.
Powered by a pair of 6L6GC/5881 beam power tubes, this combo amp delivers a solid low-end, exhibiting the rich tonal qualities of which only a pine-enclosed 15" AlNiCo loudspeaker and vacuum tube circuit are capable. Real chassis-mounted steel pots, SwitchcraftTM jacks, eyelet-board construction, and hand-soldered connections make this a rugged, reliable, and road-ready device. An optional reverb module provides classic "cathedral" ambience.
