Strange that your not getting any distortion out of the DS-1 on the clean channel....i'm assuming your amp and guitar are ok...? first thing i would check is all leads and patch cords to make sure they are working correctly.......
i got it right now and yes the patch cables were the culprits..thanks FRANZONI!
Your welcome bro..... happened to me once or twice in the past..the lead from the guitar can also be a culprit as your distortions (mine anyway )are normally near the start of the board so it's usually easy to figure the loss of drive..after the dirt pedal your would probably get the full distortion but with a loss of volume...if you see where i'm coming from.....
P.S. the reason my forum name is in capitals is because i had the caps lock when i joined the forum,i wasn't very good around computers back then.... and i never got around to changing it...the fist time i tried to log on it wouldn't let me because i typed my name and pasword in lower case.... Mrs F had to figure it out for me.......
