SOLD!!! I got this cool gadget a few months ago...all the features you'd expect for a mp3 training device and more. It also does effects and you can record clips as well! Me? I just wanna play along with my music library so all I really need is something like a Vox Amplug, in fact that is exactly what I need, preferably the bass model of course. So I'd like to trade this for your Amplug plus cash or whatever else you think you might have to make up the difference... My GB-10 is fully functional and has a odd assortment of music loaded on it which I will wipe out if you like. Straight purchase is $70 shipped to the CONUS only, paypal preferred.
