Dating
Garnet Amps

Accurately dating these amps is difficult as no production records with serial numbers exist. The following guidelines define production differences that allow the placement of a given amp into a certain era and thereby provide an approximate year of production. It's not uncommon to find amps that fall between these categories that combine features from both eras.

1965-66

The Earliest Garnet Amplifiers

  • No Company or Model Name on black control panel
  • Aluminum Chassis
  • The Garnet Emblem is brass colored and underline has "AMPS WPG. MAN." molded in
  • Squared off corners of thin brass attached with small nails
  • Sharp cabinet edges

Early Era models represent some of the first production runs of Garnet Amplifiers. Gar had been building some amplifiers in the fifties, and had produced some P.A. amps in 1963-64, but regular production of guitar amplifiers by the Garnet Amplifier Company began in 1965. Most of these amps produced in 1965-66 were likely built by Gar himself.

Getting Down to Business

 

  BTO Bass Head

New Logo features block letters, the now famous Garnet "G", underline and brass plating. Few people outside Winnipeg saw the first script logo and so this one is considered the classic original by most.

Bass and Treble clefs, a classic Garnet touch, make their debut.

Amps from this era had their control panel lettering applied with Letraset, a dry transfer lettering system, which was then covered with a thin film of clear plastic. This plastic would wrinkle over the years making these amps easy to identify.
