TGA-3 100 Watt Guitar Amplifier User’s Guide

Front Panel (Yellow Channel Tones)

The front panel is color coordinated with the FS-1. The clean channel 1 (yellow) is on the bottom row, with a channel gain and master volume, and treble, middle and bass controls. Channel 1 has the sound of a Fender amp, but with more gain control. Using this channel with the gain set to the left of 12 o’clock produces clean tones with little or no distortion. As 12 o’clock it is crossed, a vintage- type ‘bite’ is added, increasing to a rich ‘blues’ tone like the old ‘Deluxe’ (use of 6550 tubes will give the amp more headroom for an even cleaner sound). This channel has it’s own FX send/submaster (note that the red channel is also configured this way).

Bright Switch

To the left of the gain control knob is the bright switch, which functions in a manner similar to most Fenders, but with less added noise. The front input is to the left of the bright, and to the far left is the channel select switch.

Green Channel

Above the yellow channel 1 are the green and red channels, 2 and 3. These two overdrive channels share the same tone controls: treble, middle and bass. Channels two and three (green & red) are variations of the same basic overdrive architecture; it’s like having a high-performance engine with two superchargers. As you become accustomed to the amp, you will set the gain and master controls of each channel for smooth or radical channel transitions.

Edge/Boost Switch

To the left of the green channel’s gain is the edge/lead switch. When set to edge this control changes the gain structure of the amp to behave like a vintage premaster volume Marshall. With the gain control or your guitar volume, it’s possible to govern the amount of edge distortion. The lead mode incorporates a more ‘modified Mar- shall’ type of distortion, with an added volume boost for more dynamic change from rhythm to lead. Careful ad- justment of the gain, master and tone controls will produce the full gamut of British sounds, including ‘Hiwatt’ and ‘AC-30’-like tones. Again, try different output tubes for still more variation.

Red Channel

The red channel three, with it’s extreme feedback and sustain, goes beyond channel 2’s distortion for more mod- ern sounds: Heavy Metal, Jazz Fusion, The ‘Seattle’ Sound. This channel has a dark switch which emphasizes the lowend thump’ like the ‘bass boost’ Marshall mod. Like the ‘clean’ channel 1, there are red treble, mid, and bass knobs which also control the tone on the green channel two. Note: the dark switch also affects channel 2, though not as much.
