By activating the More Drive (Yellow light + Blue light), stronger saturations are achieved, but always with that slight compression that makes the saturation very soft and creamy. The tone knob has been studied in such a way as to allow the limitation of harmonics with high levels of gain, or to lighten the tone with a low to medium levels of saturation.

The tone and volume control are features in common. In addition to these features, the Dual Drive offers the opportunity to work with two different clipping circuits, just by a switch. The choice of clipping is highlighted by a two-color Red/Green LED, and ranges between a vintage overdrive sound and one with a more modern sound, with a greater quantity of harmonics.

Its sound is elegant, lightly compressed, with creamy mids that cuts through the mix. Its circuit is extremely quiet due to the many arrangements made and the selected used components.

The CostaLab Dual Drive is equipped with a mechanical "true bypass" switching system and with an anti-pop filter too.

The unit is powered by 9 DC volts and is connected by the classic DC 2.1 mm plug with negative pole-center. The current draw is less than 20 mA. 

The unit is 60x111x30 mm not counting the knob and the jacks.
