well im looking for a kod to do to my ds-1 that will give it the best metal tone . I dont know much about many of them but I am planning on the keeley mod is there anything that gives a better chunkier sound?
trust me, don't waste your time or money. Modded Ds-1s certainly sound better, but there is WAY too much midrange coming out of that pedal to be considered "Metal".

I suggest you just go purchase a Metal designed pedal instead. It will save you the hassle and probably money.
well im gonna mod it anyways so it at least has a purpose in my rig even if i just use it as a boost as of now though it makes my town sound like kinda fake and flimsy
