Hi guys!

So i have this guitar :
IMG_7076.JPG

since this february.. It is awesome but has one issue - it is neck heavy as hell.
The first thing I did for this issue was to install a piece of led in the electronics compartment to counterbalance the neck :

And it works pretty fine except for the fact that the guitar now weights a ton (10.5 kilos to be exact) after adding this 1.3kg piece of led. But really it is fine as the whole weight is just properly distributed and doesn't tire you at all in contrast to the neck heavy situation which really caused a lot of pain in my left hand almost disabling me to play the thing standing for more than 5 minutes. So ok I fixed the problem but then I continued thinking in the direction..
It seem like the neck of the thing is way out of the body - the upper horn is extending to the 15th fret compared to a regular scale it should be around the 12th fret and that basically puts my left hand in a bit odd position when playing on the first couple of frets and also justifies the neck heaviness prior the led mod.
Well you'd probably say that it is expected with a 30" scale instrument and I agree but I couldn't help myself stop thinking about a solution for this or at least a try. Reading this section of the forum didn't help either as it made me very keen on building a guitar myself :) so I decided to experiment with a different body shape that will push the neck further into the body making my left hand come closer to me but pushing my right hand a bit away but to a point of some equilibrium so that both hands' positions will suffer half the severity of the extended scale. Thats what I came to :

Then I thought why not build it from a different wood to explore some more about the wood tonality although I love the sound of the ash. I decided to go for a maple body and I am still not sure what will be the impact of that choice..

So lets see the building process :

1. Cutting the thing with a jigsaw :

2. Making the surfaces flat with routing machine for metal work (thats what I have) :

3. after some hand work on the edges it was time to route for the neck pocket, the pickups and the electronics compartment :

4. Then again a lot of hand sanding to make every surface perfect :

It was time to put the clear coat finish. Then sanding with 500 grid and then another coat and here we are :

this is today's status :hbang: and I hope I can finish it this week. I need some advice on what to use for the final sanding polishing to make it as perfect as possible (as the coat was applied with a brush there are inevitable uneven bumps that i need to sand off)

Thanks dudes :) I just added some more pictures that i forgot just before the paint job. I will be very thankful on your advices for the final sanding and polishing. I have read in multiple threads that the guys use steel wool but as I have no idea what that is I'd like to see a picture of it and as well some explanations : is it also classified on grids and what grid I need, how should I work with it and anything you think I should do to make the job perfect. May be also .. should I apply extra coats?!

Whoa! That's fucking killer, Stefan. I'm pretty much a 99.9% sitting-down player, so the neck dive never really bothered me (I can't believe you had almost 1.5kilos of lead in the control cavity, haha - that thing was already heavy as fuck) but that looks like a really nice idea and really well carried-out!

If you get a chance to record a clip of how it sounds with all that maple I'd be really interested to hear it. Hope you're still enjoying it other than the neck-dive!

Also, this is what steel wool looks like, and it does indeed come in grades. These are a bit more confusing than grades of sandpaper, though - they range from 6 (the coarsest kind which I don't think you'd ever really find much occasion to use) to 00000 (the finest kind that I've seen, which is the grade that I use to polish my frets).

Hey Fred! Really glad that you like the modifications (For those that don't remember - Fred was the original owner of that 8 string monster). I totally enjoy the guitar man, despite the heaviness. It really ain't a big issue and with the added led chunk it is also more stable in a sitting position. I really have to work out something about recording some short stuff with the original wood combination before I install the maple and then record the same stuff with the new body - it will be pretty interesting to hear the differences.

Thanks a lot for the info about the steel wool. I already found steel wool in a big shop and took the finest 0 number grit. I am still not quite sure what will be the effect of using it though but will see :)

Hello guys! The new body is already on the neck and I am sooo excited of the result! Can't really believe it came so good - everything I expected from this replacement body just happened (apart from the fact that I expected none of what I expect to quite happen :lol:) : The guitar is now just unbelievably comfier, it has perfect balance (without additional load to compensate anything) and weights quite almost as a normal guitar. The sound is wonderfull actually - this wood seem to have removed just a bit of the top frequencies edge and also seems to have less bass which I find perfect for an extended range instrument - the result is extremely tight sounding instrument. Well.. enough speakin.. I think I better let the guitar porn speak for itself as I prepared a lot of stuff for you there :

Yeah.. lots of wires here - 3 way lever and two push/pulls to give me pretty much every pickup mode that makes sense :idea: like John Petrucci wiring and paralel neck as well as the common ones

Some comaprisson photos next to my RG - notice that overall the guitar aint so long now. I think it will most probably enter in a standard gigbag..

And some videos to show the tone difference :

YouTube - Agile 8 string Ash versus Maple test on some sevenstring distorted stuff

YouTube - Agile 8 string Ash versus Maple clean sound test

YouTube - Agile 8 string Ash versus Maple true test (Meshuggah riff ofcourse :D )

Can't make those embedded..:realmad: dunno why:scratch: whatever..


This is the rig used for the recordings :
