Boss VF-1 Effect Processor

Hi Phil,

I too have the same behaviour on my VF-1. The recommended setting for
an electric guitar in the Hi-Z input is -20db.

As for the distortion sounds, did you re-adjust the input level to
obtain a comparable signal level at the entry of the amplifier
simulator module for both switch positions? 

You will undeniably get nasty sounding digital artifacts in the
distortion if the input to the amp module is too high. 

Another (somewhat obvious) issue is the "psychoacoustic effect" of
having the ouput of the unit much louder, giving the impression of a
fuller sound in the distortion. 

My rule of thumb when programming a new patch is to set the audio
level input/output of every program module near to the limit for a
full E chord, giving the unit more latitude for the digital signal
representation. In my case, (twin humbucker les paul), I need to set
the input level knobs to their minimum at -20db.

Also, try changing the output mode of the unit in the settings menu
for "power amp", "guitar amp combo", "guitar amp stack", etc... You'll
notice the envelope of the output sound changes the distortion's aspect.

The VF-1 requires a lot of fiddling around with settings to get the
sound you are looking for, but after a while, if you respect the
formentionned "rule of thumb", you will get straight to what you are
looking for.

Fred.
