Selling a cool rare older Akai Phrase Trainer. Essentially you can loop up to 8 seconds of a song/riff/solo/etc and then either slow down or speed up the section to make it easier/harder to practice to. These came out years before modern loopers were available and were quite cool in that they can change the speed of the phrase without changing the pitch. The time dilation can also be used to make some pretty wild sounds. Includes the original box. Has been tested and works but has a tiny amount of background noise (pretty mild)
