I have been looking at a lot of all-in-one units, in no particular order: Boss GT-1000 - 38 second looper Fractal AX8 - 4 minute looper Line 6 Helix (or Helix LT) - 1 minute looper (2 minutes at lower quality?!) Mooer GE-200 - 52 second looper Zoom G3n - 80 second looper For a bit of context, I play a decent amount of solo gigs (mostly Jazz). I usually sing through a tune and comp (looping from the beginning or just after an intro), then solo over the tune. Hence the need for several minutes of looping (4 minutes is the minimum time I would be comfortable with). My current setup is an RC-1 into various amps (Acoustic Image Corus, Quilter Tone Block 201 with a McQuen cabinet using a B&C 8NDL64, and others). This works great, but I would love to shorten setup time for when I am sharing the bill, playing open mics, or at venues with a PA. Hence the need for something that could handle tone and looping. It seems that the AX8 is the only choice in this arena, but I wanted to bring my dilemma to this wonderful community to see if I am missing any choices.
