THE TAKAMINE G SERIES TP4T PREAMP
The TP4T preamp is designed for use only in G-series model guitars and are not compatible with Pro-Series Takamine guitars made in Japan.
TP4T Preamp Features
The TakamineTP4T preamp found on G-Series guitars features a gain knob, a tuner, an active shelving system EQ with bass, middle, and treble frequency slider controls, and a low battery light. The preamp is switched on by plugging a standard mono instrument cable into the endpin/strap pin jack. Unplugging the cable switches the preamplifier off. The TP4T Preamplifier is powered by a single 9 volt battery.
Gain Control: The gain knob controls the volume of the preamp. Turning this knob all the way to the left will effectively silence the preamplifier. Turning it all the way to the right will produce the maximum output.
Tuner: The tuner in the TP4T is fully chromatic. Press the tuner switch to activate it. The note being played is shown in the digital display along with either an Up or Down arrow. If an Up arrow appears the note is sharp (too high) and needs to be lowered. If a Down arrow appears the note is flat (too low) and needs to be raised. The faster the arrow flashes, the farther out of tune it is. As you bring it closer in tune the speed with which the arrow flashes will decrease. When both arrows appear and they are not flashing the note is in tune. The tuner will automatically shut off after 90 seconds. Note that once the battery drops below a certain voltage level the preamp may still function but the tuner will not. If you are still getting output from the preamp but the tuner is not functioning try changing the battery.
Bass Frequency Slider: This slider allows you to boost or cut the bass frequency
Middle Frequency Slider: This slider allows you to boost or cut the middle frequency.
Treble Frequency Slider: This slider allows you to boost or cut the treble frequency
Low Batter Light: Once the battery drops below a certain voltage the low battery light will come on indicating the need to replace the battery.
