I'm waiting on JR+ as well, since Oct. - FAMC have emailed me back (I send email every two weeks to see whats going on) - parts have arrived and looking forward to getting a shipping date soon.... but the wait has kinda sucked . FCB1010 w/ Uno chip in meantime no complaints but the JR+ smaller foot print and 3 (or 4) expression pedals will be great....
FYI Pete Turley makes 4 button footswitch for KPA - affordable option, quick turnaround - I have as back up and to use at home if I don't want to drag the MIDI board out... He goes by "okstrat" on this forum; petesprofiles.weebly.com
