We're nearly there, but to sweeten the sound as a whole, a little additional ambience wouldn't go amiss.
This is where the piezo signal - previously just sat doing very little in the centre of the stereo image - can come in handy. We've used a pretty generic reverb in Reaper - Cockos ReaVerb VST - on the piezo track, with the wet signal backed off to around -14dB so that it doesn't swamp the separation of the other tracks.
A few minor level tweaks on the other tracks to taste and we're pretty happy with our quick and easy fake twin guitar sound. What do you think?
