So I picked the oldest song from http://basilwhite.livejournal.com/tag/d
The Micro BR seems unusably frustrating for mixing tracks, but I've found another use for it. I'm recording from the guitar to the BR to the USB input, which saves a lot of hassles with pedals. The BR also has a built-in tuner and noise reduction.
I also compared the recording quality of the Ibanez semihollow I used on the old recordings against the new Fender Jag, and the Jag wins in a walk.
Drums are also coming out much better, as I've learned a better method of recording and mixing takes in Audacity: 1) Record take N. 2) Pan Take N to the right channel and Take N-1 to the left channel. If Take N is better than Take N-1, delete Take N-1 and record another take. If subsequent takes don't improve, copy and paste between the two takes to fix the mistakes and pan them left and right as a stereo "best of" take (don't 'quickmix' them into one stereo track as you lose some functionality and gain nothing.)
