The Fishman TriplePlay is another really cool product to check out if you're in the market for something that's going to add a new dimension to your playing. It's a MIDI pickup system for your guitar that's recently become more and more popular. This affordable pickup allows you to interface with your computer to play software instruments (like piano, strings, synths, etc) and record. It even comes with notation software so you can play notes or chords and it will transcribe it for you. This is all done wirelessly via bluetooth!
I'm super excited about what this thing can do and hope to add it to my arsenal soon. Check it out HERE if you are interested in learning more.
