The most hideous, worst sounding, and conceptually disgusting guitar I can think of using Warmoth parts (Basically combining all the individual things I hate most in a guitar into one absolutely disgusting guitar.) would be the following:
Agathis SG or Explorer body, hollow with F holes.
Crappy pink finish with those hideous competition stripes and any kind of binding.
EMG pickups.
250K pots with a really shitty taper.
0.1 uF capacitors.
Gibson knobs or skull knobs.
One of those ridiculous hardtail wrap-around bridges with the saddles that do not adjust at all.
Stickers on the body.
Mahogany neck (Apparently the warmest toned wood on the scale...) with the freaking plainest Rosewood fretboard you have ever seen, satin finish.
Headstock painted black (The body is pink...)
The biggest frets there are.
No inlays.
Either a KWS headstock or a tiltback Tele headstock.
A POS plastic nut.
POS Squier tuners, crookedly mounted, and mismatched with the rest of the hardware.
Eyelet bolt strap buttons, with strap duct taped to the body.
