i just finished an Aion Pereladra Deluxe (BB Deluxe) build and modded it for bass and it sounds great. much better than the standard Aion Perelandra with the their suggest bass mods.
here's a pic of my build:
I've looked at the schematics, and the differences are so few, that I'm thinking of making an AC/RC/BB – BASS Pre/Booster All in one.
Again looking at the schematics, you could easily mod your standard Perelandra to Deluxe spec, ie the mids knob (mainly, and of course include bass mods).
