Most guitarists have some type of
pedal board which has digital multi effects, amp simulations
and speaker emulations. Typically these have a stereo line
These usually sound great at home using headphones straight
from the pedal board or connected straight into your home
studio or HiFi system.
Once you get on stage you then plug the pedal board into a
guitar amp (in mono) which flavours the sound depending on
the make. It typically doesn't sound as good as straight
from the line out.
Why not consider abandoning your guitar amp for gigs and
either plug your pedal board straight into a dedicated small
PA system or into the main PA (if you have monitors)!
You would be amazed how good this can sound, using the pedal
board's full range of sounds without colouration.
