9 - 18 volt DC
The Costalab Natural Drive is a pedal built on two cornerstones: dynamic and expressiveness. Its circuit is based on more traditional network of distortion with symmetrical clipping. The presence of germanium diodes gives a vintage flavour, very round and full of harmonics.
The guitar tone is not modified in any way, even with the sustain set to the max, using the volume control of the instrument or just playing with dynamics very light, you can return to the clean sound, viceversa, using it with a energetic playing, the Natural Drive responds by producing a distorted sound rich and incisive.
The feeling that results is the same that you get playing with the old single-channel tube amp, pushed at maximum volume.
Once you reach the right dynamic feeling, the expressiveness of the guitar player is made very prominent.
Despite the high level of distortion reachable, the pedal keeps silent thanks to the excellent arrangements made to the circuit and to the selection of the best components. The tone control is of the DTC, that is Dynamic Tone Control. Basically it interacts with the gain control: when using high levels of distortion, the sound becomes rich and open, so the tone should be set accor- dingly, on the contrary, with few gain, the sound is more closed and less harmonious, by opening the tone it compensates for this natural feature.
The CostaLab Natural 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 can also operate with a 9-volt battery. In this case the circuit is on by the input jack.
In order to save the battery life it is recommended to remove the input jack from the socket when you stop using it. You can still keep the battery inside the pedal even when it is powered through the DC socket, for the external power supply system is able to automatically rule out the battery.
The unit is 118x98x34mm not counting the knob and the jacks.
