This is a very sought after portable processor. I think it's better than the Katana:Go even though they are both based on the same engine. The Pocket GT holds 99 presets, can be edited in the Pocket GT software for Windows & Mac as well as Android and iOs. The PC interface is sweet and gives you control of everything this thing holds. You can also load YouTube videos and play along. The coolest feature is you can place presets on the timeline in sessions mode so you can change from clean to a lead without having to stop or step on something. 

I don't know why Boss discontinued this but everyone I know who has one loves it. The compact size is awesome for on-the-go playing anywhere because it also has a rechargeable battery. Maybe the $249 price tag scared people away but I think it's worth it. I think my price for this like-new gadget is a really good one.
