Do I have broad band, well, yes and no. At home I use an ancient 56K modem that maxes out at 28K. At work I have a T1 so I can do anything there.
I've done collaborations before in that way. Record at home, copy to laptop, email at work, etc. That's worked out good in the past. email can be flakey sometimes so it helps to have server space available to act as a middle man. That way, you just send links through the email and you can get the huge sound files when you want them.
For recording, I use ACID 2.0 for my stuff. I need to upgrade at least to 3.0 for better mp3 support. I litterally bought ver 2.0 the month before version 3.0 came out. Now that ver 4.0 is out, I should be able to find 3.0 in the bargin bin somewhere. With that in mind, a collaboration sounds fun.
Good ear on spotting the Dropped D tuning. I still feel like I should solo over it, but I never got a good solo tone on the guitar. Once I find the right tone I may add one on. Otherwise it's just a pop song waiting for lyrics. I wonder if Chris Cornell is available this weekend?
