No offence Groovebass, but if we follow that logic modern musical instruments are all unnecessary, why plug in when we could listen to a full orchestra and nix the need for amplification!
This guitar with the heavier strings tuned up to pitch as opposed to tuning lighter strings down, and with its long scale (we hope to eliminate the inhereant floppiness) will offer a different feel and a different sound to a regular or even 7 string commercially available guitar. And in a band setting moreso. This guitar is being used in an all out grind act which has stripped down its members to become a three piece, so it has got it's work cut out for it!
She is encroaching on bass territory, but thats why i thought id share the progress pics with yourselves!
Dont want to sound narky but whether or not it's necessary has already been thoroughly considered by the guy who's going to play it.
And bigwan, you and your tapping guitar, we'll get you a piano with a xylophone on top! Jus jokn

Itll happen, just got a few things to finish first
peace
