R-Zero
Acoustic Guitar Reference Preamplifier
The first pre-amplifier of Enfini Custom Works,
It will be able to be a reference for the acoustic guitar,
I named it that means Reference-Zero
as product starting from the 0th.
The R-Zero is a dual-channel preamplifier system for exclusive use of acoustic guitars
to make full use of a technique of the studio quality and parts, and realized the sound
that was extremely natural and flat.
The R-Zero can express the stereo-phonic sound and presence of acoustic guitars,
and even express the air movement which come out from them,
so you can create individual character of the acoustic guitar's pickup sound
amazingly and natural.
This R-Zero is sure to bring all the players to the depth of the rich sound
and improve your expressive playability and it also enthrall lots of music fans !
