I bought the Mustang GT200 in late spring and have spent a lot of time with it both at home and at rehearsal. My summation - this is a very bad design and not worth the money - even at half price used. The blue tooth disconnects whenever. The amp used to let u play songs and control from your BT device at the same time - someone bitched and they removed that - prob 70% of the reason i was buying the thing. The footswitch led - channel number blanks out randomly - the switches are too close together and they are hard to stomp on during live play. The footswitch buttonology is by far the worst of any amp i have ever had. You hit a switch and 2 seconds later is accepts. You cant change banks without holding down two switches simultaneously - then u have to hit only one to get to different banks and i usually goes to a setting when u didnt want it to. Going into effects mode - you can only use three effects and they have to be the first ones in you chain when u programmed the setting. The tuner is junk - its impossible to get to it on the footswitch, then its jumpy and spastic and inconsistent. The tone of the amp - not nearly as good as the mustang III. I am selling mine after the holidays and going to try again to get a decent modeler combo amp with decent tones and access to all the effects, settings and a floor tuner. Fender really screwed this one up.
