The Boss DS-2 is a Turbo Distortion featuring two forms of distortion, by turning the Turbo knob you can select from either mode I or mode II. Mode I gives you a warm and soft distortion. Mode II brings the guitar sound to a hard and raw distortion, the mid frequencies are boosted which helps you to be heard in the mix. This mode is really useful for leads, mode II also handles Hard-Rock and Metal very well. It’s important to note that there is the possibility to hook up an external switch pedal, you can use this to switch between modes I and II which is of course very helpful during a gig. This pedal is in a very good condition.
