i was wondering, can i use my ds1 as a boost pedal? if so what would be the best setting. Id try it but im not home right now to try it out but im dying to find out.
Er...ok. I thought boost meant volume boost- what did you think it meant?
It'll give you a gain boost and will thicken up the tone.

If you want a substantial volume boost then i'd look at running an EQ with a level control in the effects loop on your amp
