Boss VF-1 Effect Processor

If you need higher levels, play your loudest "clean" guitar sound with the
effects loop engaged. Turn the level up until it's where you want it and
listen for distortion. If there's not any, you should be good to go. There's
no law that says the VF-1 level has to be set at 12:00 ;-) Just tweak it
until it sounds good to you.

"Tim, Thanks for your help. I'm getting a nice sound out of the unit
but the input level and output level are not that high. When I punch
the effects loop in and out with a delay patch on you can hear its
working perfectly. I have the input level at about 12:00. Should I
try to get these levels higher? The effects loop on my amp is -10db
return and -10db send. I have the switch on the back of the VF-1 to -
20db. Thanks for your help. Rob"
