I'm considering picking up a Micro POG, but I've also got money set aside for a Subterranea whenever IE gets rolling again. I'm mostly looking for suboctave at the moment, so would the SubT make the POG redundant? Or is it a waste to use the SubT as a suboctave? I know it does more, but is it a pain to get it to pure octave sound and back to the synthy stuff between songs? does it track well? Is the sub sound fat or hollow on the SubT? The POG is going for a good price, so I'm pretty torn. Any advice would be much appreciated.
