Tascam GA-30CD owner manual Using the guitar amp, Adjusting the volume and tone quality

4 – Using the guitar amp

Adjusting the volume and tone quality

The GA-30CD has a built-in.boost circuit for creating distorted sounds. Push the BOOST switch to turn this circuit ON. The indicator to the left of the switch lights when it is active.

When the BOOST switch is OFF, the guitar input signal is output as an undistorted sound.

The GAIN knob always adjusts the guitar input volume, but when the BOOST switch is ON, this knob also adjusts the amount of distortion.

The CENTER VOLUME knob adjusts the total output volume from the 6.5-inch center speaker, including the output of both the guitar amp and any active effect.

Adjust the BASS, MIDDLE and TREBLE knobs to alter the tone quality (frequency characteristics) further.

NOTE

The CENTER VOLUME knob adjusts the overall volume of the output signal sent to the center speaker (6.5-inch). If an effect is used, it will be output along with the guitar amp output.

The BASS, MIDDLE and TREBLE knobs reduce the levels of frequencies in specific ranges. At 10, a knob does not cut its frequency band at all while at 0, it cuts its band to the maximum effect.

Procedures to shape the guitar tone

1Turn the CENTER VOLUME and SIDE VOLUME knobs down to 0 (all the way to the left).

2Connect a guitar.

3Turn the BASS, MIDDLE and TREBLE knobs to 10 (all the way to the right).

4Turn the GAIN knob to the middle (pointing up).

5Turn up the CENTER VOLUME gradually while playing the guitar until you reach the desired volume.

6Shape the tone by adjusting the GAIN, BASS, MIDDLE and TREBLE knobs and turning the BOOST switch ON or OFF.

7Choose an effect (see “Selecting Effects and setting Parameter” on page 14) and adjust the three effect knobs to shape the tone further.

8Adjust the CENTER VOLUME and SIDE VOLUME knobs as necessary to achieve the volume balance that you desire.

Of course, you can adjust the knobs in any order that you like, but we recommend that you always turn the GAIN and VOLUME knobs down before starting and before connecting a guitar.
