Re-learning and re-recording all the guitar parts, including the acoustic (using a mic instead of pickup), some slight tweaking to the levels and EQ, effects on the harmonics, automation.
Re-added the "real" drums to the original (v2) recording.
Simple repeating motif, but spread across three guitars for some nasty grinding tone.

Re-learnt the guitar bits to fix all the mistakes. Here's the 1st draft of me having to learn my own song!
Yet another slight tweak to the mix. Beefier kick drum, louder snare, less booming bass, boosted lead guitar in the solo, and a little added extra synth in the outro.
