DYNA AMP
This is an original amp type that lets you obtain unprec-
edented tonal changes according to your picking dynamics.
Soft picking produces a transparent clean amp sound,
whereas hard picking yields adeeply distorted high-gain amp
sound.
Once the sound is distorted, the tone then changes according
to the force used in picking, greatly expanding your range of
expression.
Setting the [GAIN] knob at the optimal position provides
maximum eectiveness. Start with the [GAIN] knob centered.
Then adjust the [GAIN] knob so that soft picking yields a clean
tone and hard picking produces heavy distortion.
[GAIN] knob
This adjusts the distortion level for the LEAD channel.
[VOLUME] knob
This adjusts the volume level for the LEAD channel.
