I really love this looper! It is so much fun to play that you lose track of time.
The Boss RC-3 comes with about 10 demo tracks installed so the first thing I did was plug it into my Mac and copied them for safe keeping. The RC-3 appears as a regular USB drive, so all you have to do is copy the entire folder. The drive contains 99 folders, one for each preset, so if you want to download a new trac, just copy your wave file into the appropriate directory. Works great, and nice and fast.
Speaking of the demo tracs, the RC-3 has a sweet Blues trac that I was soloing over it. Even though I'm still very much a beginner, it sounded really good! Better yet, it is so much more fun to practice with and I think it's helping with my timing (which isn't very good either).
One thing I did find is that the RC-3 does not work well with my
One-Spot power supply. When powered in with the OneSpot there was a lot of noise and, worse yet, when cycling through the presets you can definitely hear the CPU clock of the RC-3. No worries, I pulled out an old Radio Shack wall wort, and it sounds perfect.
There are a lot of guys on The Fret that recommend getting a looper (thanks again, Cho!) and you can now add me to that list. These little things are a blast! :dude
