I would use my Ibanez SR1205 as a template and then make a few alterations. So, I would take the:
5 piece maple/wenge through-neck with SR5 neck shape
Mahogany with maple top body, SR shape
34" scale
and then go for
EMG 40TW in neck and bridge
EMG BQS preamp, with two toggle switches to the side for the pickup splits
Chunkier bridge (Badass V, perhaps?)
Ebony 'board
And, as I'd like the body's maple to be flamed, I'd like a translucent green finish please.
That is it. If I were to go custom, that would be it. In fact, that's been "it" for quite a while. Luckily for me I already have the SR1205, or GAS would be killing me right now.
