I've been playing around with the Zoom H4 and Audacity a little bit more today. This is addictive and very time consuming fun but very frustrating too. I've found it pretty easy to navigate around the H4 menus even with the little screen and small controls, but i must say that they should have made it easier to delete takes quickly.
Why does this matter ? It is infinitely harder to be a musician than a luthier ( which is why they get paid better

). If you can't lay down a track perfectly and aren't into spending many many hours in front of a digital audio workstation fixing things up, you end up doing take after take after take until you get one thats close. And let me tell you, as a plunker rather than a musician my chops are so irregular and fumbly that I end up doings
lots of takes to get one that is moderately unembarrassing to post, especially on a concert ukulele sized fingerboard.
My H4 came with a 128MB SD card and that doesn't hold a lot of data at a 44.1khz/16bit PCM encoding rate. I have a 2GB card on the way and that will help a lot but meanwhile I wish it was just a little easier to delete a full card and restart recording

None-the-less i think the H4 is a sweet little product and well worth its price.
Sweetwater has 'em, and great customer support too.
In any case, i wanted to get a little strumming on the new koa concert down. Here is a short take of
The Working Man's Blues. Its recorded using the H4 built in mics, medium gain, the U87 mic model, no effects. I imported the PCM file into Audacity, normalized it, added a tiny bit of plate reverb and converted it to mp3 format.
