Hi Axe. I have the BOSS JS10. The solos I've posted were recorded with it. Its a great practice tool. The backing tracks it comes with are really good, plus you can find MP3 backing tracks online, load them to a USB thumb drive, and then just stick the thumb drive into the JS10 and play those too.

The downside of the JS10 is its expensive, and it doesn't sound that great through its speakers. It does sound really good through the headphones.

What I would suggest is that you do a "search all of Craigslist" for one (which is what I did) and you'll probably find one. I got mine for $200, and it was like new. Or you can just skip the hassle and go new. I use mine every day. Its one of the best investments in music gear I have ever made.
