Boss VF-1 Effect Processor

Hello again !!!just one thing,the first time i try the vf-1,i was about to 
put it and break it on my amp!!!that's true!be careful ,there are some 
adjustment to do to be shure to have a killer sound(if's you play on a pc,a 
stack a combo,etc...)(but not only that:it's depend the type of amp you use 
the impédance of the re turn line etc..)but when you understand what 
adjustment goes or not you can do everything mostly ;if you have an ugly 
sound don't be afraid ,you can wrote i'll try to help you if i can...bye.
