Hi Julian,
Nice Epic! I for one cannot understand why people dislike the shape - it's less gothic in nature than some of the other designs, and so it can show off the beauty of the top wood rather than drawing attention to itself. Not that that is necessarily a bad thing, just a matter of taste and opinion - I can appreciate both.
Even with the 'lesser grade' standard wood choices, they always make sure that the wood grain complements the body shape. On your Epic, I really like the wave of the grain pattern growing out of the bookmatch-to-center. It may not be superb flame walnut, but it certainly looks like flame walnut to me.
The standard electronics on an Epic are the same as on the Orion - the only difference between those two is the shape of body and headstock. It's not really clear from the site, but I think they're now fitting the Excel with an MXY and a FatBoy (instead of two MXYs) and the same electronics.
As always with Alembic, you can order pretty much any combination of features - within reason: they'll tell you if something cannot be done. For an electronics upgrade, you need to understand that not everything will fit into the cavity, and also the holes already drilled may not match the new electronics.
With the Epic package, you have vol/pan/bass/treble. If you upgrade from that, you also get into a different type of tone control.
The basic upgrade would be the Essence package, vol/pan/filter - for which I'd recommend adding the Q-switch. If you look at this month's Featured Custom, you'll see that they've added the filter and Q switch to the Epic electronics. This probably won't fit into the standard cavity, so you'd need to send the bass to the factory for the upgrade.
Next up from that would be the Europa/Rogue package, which is the same as on the Essence, plus a Q switch and two boost switches for bass and treble.
Next up from that you get to the Signature package, and I'm pretty sure that's when the control cavity must absolutely be enlarged.
