A few months ago, I posted a thread about Brian May inspired wiring for a metal guitar. As a youngster I was always fascinated by Mr. May's legendary guitar tone which made a Queen song recognisable IMMEDIATELY as it starts playing. I was thinking to build a guitar that would give a similar tone options that he had and could still handle the standard Death Metal guitar tone.

I'm writing this thread to get some feedback from fellow forum members and to share my progressing research and all the opinions of various people to who may have also wished to own a versatile guitar but never had the money to buy one.

I also know that the guitar isn't everything to obtain Brian's tone. I have an Ehx Screaming Bird treble booster and for the moment I can't afford 2 or more Vox AC30 and the maintenance that comes with tube amps.

----------------------------------------------------------------------------------------------------------------------

To start off, I should probably clarify that the type of Death Metal that I play with my band is very progressive and influenced by Prog Death Metal bands like Opeth, Edge of Sanity, Cynic, Atheist, Akercocke, Nile and etc. while also having lots of impact from bands like Queen, Led Zeppelin, Camel, Primus, Deep Purple, etc. so the stuff that we do requires me to be able to change the tone completely, This is OK in a studio environment where you have the time to manipulate your sound as much as you want me being also the self-thought person behind the mixer; but this all changes in a stage environment! So I decided to put my O-level in physics, the 5-hours-a-day I spend watching Discovery Channel and basic woodwork skills to good use, and figure out a way to build a guitar that can:
  • Change the tone (even completely) by the flick of a switch
  • Call on feedback on demand (again Brian May influence :laugh:) for solos making it go from absolutely no sustain to infinite
  • Give great acoustic tones
  • Be as light-weight as possible (I deal with minor shoulder strains when I play standing up; although the shape of my current guitar (a Flying-V) really doesn't help :/)
  • Be at a reasonable price as much as possible.

So now I came up with this guitar design (I used http://www.nymphusa.com/tele/yswtct-kisekae-e.asp and then tweaked it with MS Paint):
Untitled.jpg
Specs (I'll probably buy a cheap Harley Benton build-it-yourself set and use its neck and craft a body with reference to the given one and make it thicker to house the controls with more ease. They only cost about €95 plus you get many spare parts to work with ;) ) :
  • Maple body hollowed out quite a bit with a 3-ply wooden (the type of wood used for fretwork) or a plastic pickguard (depends on which sounds better to my ears) to feedback a little more like Mr.May's and produce a "poppy" sound that seperates the notes better and provide more realistic acoustic tones.
  • Medium thick maple neck to sustain and "pop". The thickness is to retain a little more "Fatness" that's lost from the hollowed body. The neck is standard strat scale (25.5") which is unlike Mr.May's (which is 24") but will keep the bass notes tight in a high-gain situation. Tuners are locking.
  • Rosewood fretboard jumbo frets with the last 3 frets gradually scalloping deeper so fretting them would be a little bit easier
  • Brass Roller Nut for smoother action when using the tremolo and the brass gives a bit more attack http://www.thomann.de/gb/abm_7020c_roller_nut_st_style.htm
  • Fishman powebridge tremolo (a piezo pick-up for even better acoustic tones) http://www.thomann.de/gb/fishman_powerbridge_modern.htm

This is an image showing the switching options and the pick-ups:

Artec Soul Zone PSZ I-B

(just to clarify, they are intended to all be bridge pick-ups)
I'll probably upgrade these to 3 Burns TriSonics and 1 Duncan SSL-6

My philosophy about choosing this pick-up configuration:

For neck:
When switched in series, the neck "humbucker" will compress the signal quite a bit because the coils are identical which in turn gives a little bit more sustain for soloing. The low output level ensures that the signal keeps its treble frequencies intact as much as possible. The reverse phase option is an other thing inspired by Brian May which is rich in harmonics and makes the guitar scream.

For bridge:
The difference in the output level of the coils can give the signal more dynamic range when in series which is good for any fast riffing because the notes are more separated. The high output and alnico magnet are useful for getting more "fatness" as well.

Other possibilities:
Neck in series + the white coil of the bridge in series with the neck: This, in theory should compress the signal further giving more sustain and boost output because all coils are the same. with a hollowed body, it shouldn't lose the high end completely.

All 4 coils in series + piezo: This should give MASSIVE amounts of output and the piezo should return some of the lost high end. I think that it would sound great both on clean because it would be warm while still hearing the "jingle" of steel strings and in high gain would still keep that bite.

Now for the schematic (I apologize for sloppiness :/ ):

I hope the caption in the image is legible :/

Improvements done to previous designs I had came up with to preserve as much tonal value as possible and make the instrument more "user-friendly":
  • I'm using on-off-on switches instead of on-on-on or on-on to eliminate the need for on-off switches to turn of parts of the chain. This should in turn reduce some resistance (not much but it'll still help) giving off a slightly hotter and fuller signal.
  • Because this is a strat and contains lots of space under the pick guard (which I'm going to be hollowing out even further) which can be used wisely. I came across some wire which has a greater cross-sectional area than the standard wires used (it's 5mm in diameter whereas the ones on my Dean VX are 3mm). A thicker wire further reduces resistance to the signal. I'm also going to be using the shortest lengths of wire possible to further reduce resistance.
  • I'm using a stacked pot instead of 2 separate ones to make the circuit more compact plus they can be both turned down by one "swipe" on them.
  • The locking tuners and roller nut increase the tuning stability when having a tremolo.

----------------------------------------------------------------------------------------------------------------------

I hope you like what I'm doing so far. The whole thing is going to cost me up to about €700-€800, which will probably take some time to save up for it because I'm still in school but to be honest, I think that it's totally worth it because when a player builds his own guitar, he builds it exactly to his own needs and with ensured quality without having to pay for big names that companies have. It also would be an opportunity to the player to learn more on how his instrument works and find out more what it's capable of doing.

This would also be a good science project :D (If it's ready by a few months before the deadline I'll probably do the project about it ;) )



Before I close this post I would really like to apologize about making you read a lot :15: . I hope you at least found it helpful


Don't forget to post any feedback :D

Re: The Homemade Guitar.

So you want to fit 9 DPDT switches, 2 pots, a 3 way toggle and wiring under a Strat pickguard? Good luck with that. And why would you choose Artec pickups to emulate Brian May?
 
Re: The Homemade Guitar.

They are temporary cheap ones which I'll consider upgrading in the future when I have more money.
And I will be making a deeper Strat body to fit all that stuff in. I was thinking of a 5.5cm thickness which surely covers it

I'll clear that up in the first post^^ :)

:eek2::why:
 
Re: The Homemade Guitar.

Why not just save up that little bit extra and get a decent set of pickups so that you don't have to bother with upgrades in the future? 100€ extra should get you a nice pair of pickups (I'm guessing? I don't know how prices work in EU)
 
Re: The Homemade Guitar.

first of all, i admire your vision.
secondly, you're one crazy bastard, and i like that.

but:
define how much brain may you want in the mix? brain may and his dad built his guitar out of firewood IIRC, and it's a short-scale with 3 single-coils which is very different from what you're looking at doing here.
i get it if you're looking for a recognisable tone, and i hate to be the dreamsmasher, but that tends to come a player's approach and idiosyncrasies.

getting back to your project, the pickups are the very last thing i would cheap out on for this kind of expedition, for several reasons. spend a bit of money on good pickups the first time around; i say that because i would consider it very wise to build the pickups, switches, harness etc properly and try it in a cheap-arse partcaster first and see if you actually bond with it, before spending time and money chopping into expensive pieces of nice wood (which you can transplant your... creation into later).
remember that the pickups, switches and hardware can all be salvaged should you choose to abort the mission.

have you considered going active, and/or using on-board effects?
 
Re: The Homemade Guitar.

Passive piezos sound terrible and won't get as loud as the magnetic pickups. Doesn't look like there'd be room for a battery and preamp though.
 
Re: The Homemade Guitar.

My suggestion on the piezo is to buy a small piezo booster/preamp without need of a volume and switch control (like the Graphtech acoustiphonic) and add a small battery box otherwise the piezo will sound poor
 
Re: The Homemade Guitar.

Such an adventurous endeaver!

There are many positive comments I could make about the tone and versatility, but you are already aware of that so I won't.

But in an effort to hopefully be helpful, I DO have a couple comments.

I would hope that you made a mistake in saying you plan to use 5mm diameter wire...that's about twice as thick as the main power supply to my house. I'm sure you must have meant .5 (1/2) mm.

All coils in series is gonna equal mud.

You are going to have so many switches/controls that even if you can create enough room to hold them all, when you are playing you'll be concentrating so much on which switch to flip that you'll not be able to remember what to play, lol.

But good luck to you. The inventive process can be as much fun and rewarding as the playing.
 
Re: The Homemade Guitar.

Whhaaaaaaaaaaaaaat da heck...

Seriously, I struggled with Three toggles on my strat along with the standard knobs and 5 way switch.... man... good luck to ya.
 
Re: The Homemade Guitar.

we get one of these on here every couple of years or so...

the Insanely Convoluted Attempt to Make a Guitar That Does Everything At Once Guitar.

It almost never works.

This one is my all time favorite, but yours is almost as creative / insane.

You will get much, much closer to having good classic rock and death metal tones by spending the money you plan on investing in this project on a decent tube amp... talking about the maintenance of a tube amp like it's a huge hassle and then designing a circuit with that many switches on the face of a Strat is downright LOL-worthy.

I can play convincing Queen / Zeppelin / Rock tunes and get really good metal tone out of one amp, one guitar, and a few pedals...
 
Re: The Homemade Guitar.

I would simplify. A lot (probably most) of what you are asking for comes down to how you actually play the guitar, not how many tones you can switch to.

IMHO, the #1 thing that makes Brian May's tone distinctive is that his guitar is short scale, like a Fender Music-Master, Duo-Sonic, or Mustang. With a versatile rig and creative processing, you can get all sorts of tones from any guitar, however, no effect or other studio trickery will simulate the sound and feel of a short-scale guitar...and in my eyes, a huge part of anyone's tone comes from the feel of a guitar, i.e. how your hands interact with it. Most people skip the short scale consideration when trying to nail his tones with a different sort of guitar. Bad move IMO.

So, the very first thing I'd do is purchase (or construct) a suitable "base" guitar that is one of those models I listed above, or based on them. Aside from the scale, the other thing that makes them suitable is the switching. On the later Duo-Sonics, not only could you run the pickups out of phase with each other, but they were also wired in series. Add a switch, and you could go to parallel. With Mustangs, it was the opposite. They still had the reversal switches, but they were wired in parallel, and you could add a switch to make them series.

Re: The Homemade Guitar.

let's not forget the treble booster

I have not forgotten it. I just don't think it made as much of a difference as the rubbery feel, muddy tone, and super fast neck of a short-neck guitar. I would even venture to guess that it could be a large part of why he started using a treble booster in the first place.
 
Re: The Homemade Guitar.

Close, but not quite. It was originally an oaken firePLACE if memory serves ;)

hey, that does sound right, now that you mention it
i vaguely remember reading an interview with mr may in an english guitar mag in the early 90s... that's about all i've got!
i'm just happy i can remember anything i read that long ago, heh heh.
cheers man.

all coils in series are a Jimmy Page invention and I mean 5mm thick wires (including the outside insulation).

And it seems that many people think that it's going to be impossible to fit everything inside the body. So I'll get back to the drawing board and see what I can come up with. If you have any ideas on how everything could be fit inside just post. :)
