User Reviews of the Guyatone Guitar Exciter & Comp Double Effect PS-021
Submitted by Tham from Kuala Lumpur (10 points) on Aug 4, 2006
I'm not a guitarist, but I believe every playing guitarist
should have this unit.
My friend used one on his setup around 1986, in line
after the distortion unit, such as Boss's Heavy Metal.
You could get virtually any kind of distortion sound
with it, because the "Color" control, you can vary the
harmonics from even to odd. The "Exciter" adds a
brilliance to the sound, similar to the Aphex Aural Exciter,
so it can even be used for vocals.
With the "Color" turned to the left, around 9 o'clock, you
would get even harmonics, close sounding towards a
tube amp's distortion.
Placed after the distortion, you could step on it when
you wanted to do a solo, as it would boost your sound
level up as well.
This was a really versatile, superb and underrated effect,
and none of the other effects manufacturers made an
equivalent unit. The closest I could find at that time as
Dod's Harmonic Enhancer, and this had no "Color" or
compressor built in. Boss had no such effect in their
Most guitarists were ignorant of the existence of this effect.
Good Points: Highly versatile "Color" control lets
you get even or odd harmonics.
Superb "Exciter" control to add
brilliance and depth to your sound, similar to the Aphex
Built-in compressor control. You
don't need to buy the Boss
