Nice! I was wondering what two P90s would look like without a pickguard. I just ordered my first Warmoth, and it's almost a duplicate of your's. It's not here yet, but I hope to see it on my doorstep in a few more weeks. I went with two P90s w/o a pickguard, similar rear rout with the same volume/tone knob layout as your's, but I put the pickup selector switch up on the upper bout (like a Les Paul). I went with Sonic Blue and cream Sanford Magnetics P90s (as featured on The Doug and Pat Show
