GAMMA

collapse expand iconDescription

The GAMMA True Blue TB12G 12” guitar amp speaker is ideal for upgrading amps that deliver up to 60 watts of power at 8 ohms. Its 40 oz magnet is larger than that of most other guitar amp speakers, and is essential to the outstanding headroom, clarity and dynamics that the speaker delivers, along with ample low frequency response. The True Blue TB12G is equally at home in delivering aggressive high-gain distortion, transparent cleans or medium-gain distortion, and is a go-to driver for translating tones from your stomp boxes or multi-FX and modeling units.
