Integrating a stompbox circuit into guitar...

[DUY1337GUITAR]

At the moment, I'm waiting for the nitro lacquer to cure on my refinished guitar.  It's been a month already, but I'm going to wait another just to be safe.
I want the electronics in this guitar to be unique, so I was thinking of adding a stompbox circuit into it.  Any suggestions?  I got the JFET preamp in mind (and already tried before, loved it), but I was thinking maybe you guys would have some good, or radical, ideas.  I know there are many boost and EQ circuits, but I'm not familiar with any...

Here's the guitar that's going to be modded:




Thankful for any help!

What about a stratoblaster? Thats what this circuit was designed for after all. You could also try something along the lines of a rangemaster. What sort of music do you play?

I've become rather ambivalent about on-board installation, but I understand why some folks want them.  Whatever you decide to put in, the following factors should be taken into consideration:

1) How much current does it draw?  Ideally you want something that you can run off a battery for a very long time before having to change anything.

2)  Will it be something you ALWAYS want "first"?  As an on-board effect, you will not be able to stick something else ahead of it.

3) Will you be able to provide as many or as much control for it as you want or need?  There's often a limit to how many kobs or switches you can stick on a guitar, before it starts to get way too cluttered.

4) Will it be something you can use without having it disrupt your playing in order to use it?  If it's something like a buffer to fight against a long first cable, you'll leave that on no matter what else you do.  Something like a phaser, you'lll want to turn on and off, which means taking a few moments out from playing to fritter with it.

5) Will it fit well and securely inside the space you have available?

None of that precludes installing something onboard.  All of it increases the likelihood that whatever you install will make you happy you did so.

Thanks for the reply guys
What I'm looking for relatively is a boost or some type of one-knob EQ circuit because I can just replace my tone knob with a push/pull potentiometer.  Adding a toggle switch wouldn't be too bad.  I've built the SHO boost already as a stompbox. 

On some online stores, I've seen add-ons that replace the tone knob so that it would shape the EQ in a different behavior instead of rolling off treble.  Was wondering if there were any diagrams for that available from this website.

And I forgot to mention, I am blocking the tremolo in the guitar so that it would be a fixed bridge.  That way I have room for parts in the trem spring cavity.

As for music, this may not be your cup of tea, but I like playing symphonic metal:

But my music kind of ranges in a number of genres...

There are more, and less, complicated ways to vary the tonal character.  The Stellartone Tone Styler, shown here, is a nice little passive device that takes advantage of the tiny size of surface-mount technology to let you switch between a variety of tone caps, resulting in some very different voicings. 
YOu can make less costly versions of something like that for onboard installation using whatever rotary switch you find convenient and cost-effective enough.  I have a very simple 3-way toggle on one of my guitars to select between no tone cap, and two different tone cap values.  Not quite as elegant as the Tone Styler, but easy to install, cheap, and easily amenable to changes after installation.

Do they really make a noticeable difference in sound when you switch between two cap values?

Radical? *grin*  What about a boost where the switch is a direction orientation mercury switch? (DPDT iirc, but can't remember the name for these things).. that way when you hold it straight up you activate the boost like star power from guitar hero.
