Awesome Effects Pedal!!!!

Well I use a Digitech BAD MONKEy whihc is an overdrive pedal..... Overdrive is just light Distortion.... infact it is very subtle...If ur not into heavy distored sounds u will like a over drive...But what excatly do u mean by "soft elctric leads"? ... U can get lots of diff Distortion pedals from Overdrive to Fuzz to Hard Distortion to Grunge to Metall".. where are u located? I would suggest making a trip to Furtados if u r in Mumbai, thats where I picked up my Overdrive... also cheak this link out and cheak out the sound clips u will get a fair idea https://www.digitech.com/products/BadMonkey.htm ( for over drive)
https://www.digitech.com/products/ScreaminBlues.htm ( for a Blues distortion tones)

https://www.digitech.com/products/HotHead.htm ( this is hard rock distortion and very versatile, u can get any thing from soft rock and hard rock 80s metal and so on).
