This is quite a recent addition to my list of favourite hardware, which is probably why it is the first to come to mind. I’ve been using this with my little Ukulele and it has been just amazing. If you’re interested in hearing some of my experimentation with it, you can find them here:
I have to say that the iRig Acoustic has made these possible. I’m sure that I could’ve done them in a different way, but this device was just so easy to use that it made perfect sense. I’ve been very impressed as you can probably gather.
So I’d happily recommend it, and I’ve a few more experiments in mind for it soon too.
