With integrated buffer
9 - 18 volt DC
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 Mark II 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 accordingly, 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 Natural Drive MKII is equipped with a Class A buffer always on, characterized by high input impedance. This makes it possible to save every detail of the sound, giving definition and room between the notes, moreover, it can easily reject radio interference. In addition, the Natural Drive MKII is equipped with a system against ground loops.
In order for the system is operating properly, however, you need to power the pedal with a specific power supply is not connected to other pedals (Boss PSA type or equivalent) or a power supply equipped with electrically isolated outputs. In every case, the CostaLab Natural Drive MKII can perfectly work even with the shared power supply with other pedals.
The CostaLab Natural Drive MKII is equipped with a mechanical switching system "Bufferd" with buffer always active, equipped with anti-pop filter.
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 118x93,4x34mm not counting the knob and the jacks.
