Twin channel overdrive pedal with tube analogue vintage sound
This is a very convenient overdrive pedal. It has a clean channel, an overdrive one and an additional lead one so you basically get 3 channels plus tone control. The tube delivers a very classic vintage sound so you can use it in combination with any solid-state amp and you still get a tube sound. You can conveniently carry around without compromising your sound when you need to use random studio amps. If you combine it with a tube amp it sounds obviously even warmer.
