We're a small New England company that specializes in vacuum tube audio for the musician or music enthusiast. We restore and rebuild vacuum tube based guitar and bass amplifiers with the goals of making them as rugged and dependable as ever, while renewing and preserving their classic sound quality. With those goals in mind, we offer a line of new amplifiers inspired by the best of the older originals.

"Built the way they used to build them"

Vacuum Tube Guitar Amplifiers

Hamilton-Kolby has developed a small line of custom-built vacuum-tube guitar amplifiers inspired by the finest examples from the golden age of tweed. We believe that the magic of these amplifiers results not only from their circuit design, but from the construction materials and techniques used to build them.  They're truly "built the way they used to build them". And they sound pretty awesome too.

Vacuum Tube Amplifier Restoration

We have the experience, the know-how, and the skill required to restore your vacuum-tube based instrument amplifier to as-new condition, whether it be a recent reissue, or a gem from the '50s. If you are the owner of an older instrument amplifier -- whether a "closet classic" in great cosmetic condition, or a tired, beat-to-death amp fallen from grace, we'll do only what's necessary to bring it back to life.
