Just got myself a Boss Katana mk1 head. Not that i needed an amp but hey, i love a new toy every once in a while. It was cheap, B-stock. 5 basic channels, power switch 100/50/0,5/0 watt, lots of effects, USB, free Boss editor. What's not to like. Lo and behold, hidden somewhere in the effects section in the editor there's the Roland GR300 GS sound made famous by Pat Metheny. Perfect tracking, a little delay and reverb and off you go.
The devil is in the details: on stage you'll need the GA-FC footswitch (100 euro), an EV5 expression pedal(68 euro), 5 meter stereo jack cable (3 meter is supplied but not long enough IMHO), amp cover, speaker cable, a speaker cab of course.
