The Demeter TGA-3 is an all-tube, 75 watt guitar amplifier. It features 3 channel operation:
- Channel 1 (clean) – the clean vintage, tweed amp sound.
- Channel 2 (edge) – the ultimate classic English crunch sound (can be used as a second lead channel)
- Channel 3 (lead) – high sustain, super distortion channel.
In addition, the TGA-3 features an innovative effects loop which allows the amp to operate all three channels in a full stereo mode (TGA-SA or equivalent power amp is required for stereo operation.) As in all Demeter products, each TGA-3 is hand crafted using only the finest quality components to insure years of trouble free operation. The TGA-3 is available in an amp head.

The TGA-3 Tube Guitar Amplifier represents over two decades of tinkering, tweaking, playing and listening by James to build the perfect amp. What he wanted was an amplifier that could deliver a clean sound with a tone that rivaled the vintage Fender amps (like the 410 Bassman), a crunch distortion sound like a pre-master volume Marshall and, of course, a high gain sustaining lead tone.
The tweed cover does have some discoloration in some areas, but overall is in good. Also included is the original 3 channel foot-switch. These amps are extremely rare & hard to find.
Built like a rock with the rare torroidal transformer that only the early ones had. The clean is a huge glassy Fender sound, but then you have two killer Marshall master volume type gain channels as well. What's amazing about this amp is that the "famous artists" tones from it are so different. On one hand you have the Dumble type tones (Michael Ward, Sonny Landreth) & then you have the Dean Deleo STP tone for all of his crunchy 90’s sounds.
Only about a hundred or so ever made. It was special order only and there are quite few small variations as relates to some extra knobs on some (tube type switch, Dean DeLeo mod, stereo effects loop return etc). They are now being made by Demeter again, but this is an early on (late 80:ies/early 90:ies).
