TAKAMINE TK-40 AND TP-4

Our Takamine G Series electro-acoustic guitars come equipped with either the TK-40 or TP-4 pre-amps, each of which has been designed to provide exceptional naturalness of amplified tone and maximum ease of use. Both pre-amps feature gain, bass, mid and treble controls plus a low battery indicator, while the TK-40 offers players the added benefits of a highly accurate built-in tuner, EQ bypass, notch filter and a mid contour switch. The following provides a quick overview of the pre-amps’ functions.

Gain. The gain control regulates the output level of the amplified signal. Before plugging in, it’s generally a good idea to set the gain control to ‘min’ and then gradually advance it clockwise until you find the ideal level.

Three band EQ (bass, mid and treble). The EQ controls are active, so they can cut and boost levels within their respective ranges, allowing you to precisely control your tone and adjust it to suit your taste and playing environment. With the sliders in the middle positions, or ‘0’, the tone is unaffected and is a good place from which to start modifying your sound.

Low Bat. Following the insertion of a jack plug into your guitar, the red battery LED will illuminate for approximately one second showing that the pre-amp has been activated. If the LED glows dimly, this indicates that the battery level is low and due for

a change.

Additional features of the TK-40 pre-amp:

EQ Bypass. Bypassing EQ is desirable in some studio or live environments where external EQ is preferable. It’s also useful in that it allows you to compare your EQ adjustments to your unaffected amplified tone. With the switch in the depressed position, the EQ is active - return it to the ‘up’ position and the EQ is bypassed.

Notch Filter. The notch filter is a highly selective form of EQ that affects only an extremely narrow and deep cut of an audio frequency band. The TK-40 has a tuneable notch filter, allowing you to select the frequencies affected by the notch so you can dial out feedback. If monitor or stage levels are too high and you hear your guitar starting to feed back, press notch filter in/out and simply tune out the feedback by slowly rotating the rotary notch control until it’s eliminated.

Mid Contour. Press the mid contour button and you activate a pre-shaped EQ that emphasises the frequencies that best complement an amplified acoustic guitar. The control can add punch or reduce unwanted mid frequencies. Try experimenting with the mid contour and the ‘Mid’ EQ control to find the tonality that suits you best.

Tuner. The tuner in the TK-40 is fully chromatic and automatic. Simply press the tuner switch to activate it, sound each string in turn, tune to concert pitch and then start playing!
