15. ISF (Infinite Shape Feature)
The ISF control works in conjunction with the Bass,
Middle and Treble controls. It allows you to choose the
USA
UK
exact tonal signature you prefer. Fully counter clockwise
has a more American characteristic with a tight bottom-
end and more aggressive middle, and fully clockwise
has a British characteristic which is more 'woody' and
less aggressive.
Unlike conventional 'contour' controls and parametric equalisation systems, the
Bass, Middle and Treble controls remain interactive with each other just like in a
traditional guitar amplifier tone stack. This leads to a very familiar, musical response.
