Why pay 130 Euro for a Boss RC-1 if you don't need stereo, this one does the same job, the audio quality is fantastic and this small format is a joy to bring it with you on the go... This is for me the best looper ,don't even think you get better with a Dito!I've tried them all!this one is the best mono looper!(as long it last...i ll keep updated and of course thanks to Thomann super service .
