Tom Watters gives you a detailed explanation of the versatile, great-sounding CTP-3 CoolTube™ preamplifier that's featured in many of Takamine's higher-end guitars. The CTP-3 is the only preamp for acoustic guitar that has an actual vacuum tube -- a 12AU7 dual-triode -- running at very low voltages, and providing amazingly warm, natural tone. The CTP-3 also offers extreme tone flexibility with 3-band EQ that features shelving filters for +/- 12dB on each frequency, plus semi-parametric midrange control, precise onboard tuning and more.
