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-ounce magnet is larger than that of most other guitar amp speakers, and is essential to the outstanding headroom, clarity and dynamics 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 stompboxes or multi-FX and modeling units.
