Thanks Graham
ive never worked with them before so i did not know how it actually 
functions but after reading your post 

i did see that it works similer to useing 2 EQ's
in the EQ / Distortion / EQ chain 
( Frown and Smiley curve's ) 

Thanks alot for your time
im actually spending 2 hours a day with the 2101 artist 
and ive found it to be a blast 

ive made some nice tone findings too 
im also doing some re-amping at http://www.amptone.com 
ive learned alot from the site 

im about to place it in the front of the chain 
and try all my setups again
