The DS-1 is the well known “orange pedal” from Boss … it provides a harder distortion effect than ODs. Completely stock, I find this pedal quite toneless / fuzzy and it provides to my ears harsh distortion, not reproducing nuances of playing.
Like many others, this pedal can be modded to sound far better.
Here are samples made for my friend “Pr Torode” specialist in pedal modifications.
To record these samples, I use my Squier JV ’57, Boss DS-1 Torode modded pedal, amp simulator (and HP sim) directly connected to my Mac, very with (little) reverb.
Distortion levels are at first at 9 o’clock (OD), then 12 o’clock, then to the max. Tone is always in mid position. For each distortion position, I play first the neck PU, then middle, then bridge (you can ear little click when I switch for on PU to the other).
