Boss RC-1

It's a looper and it works, hasn't got any fancy things that you might expect given the price and there're definitely more inexpensive options out there that deliver pretty much the exact same job.
I kinda regret buying it and I wouldn't advise others to buy it, unless you want a decent, over priced and without true bypass looper.

Correction: I see the price has gone down quite a lot since I bought it. Maybe now it's not so overpriced.

Good pedal, build like tank, good sound quality and the only one out there that visualizes the loop duration which is very helpfull if you just start playing.
But it lacks of other features like metronome,banks etc and it has just 1 button, making it tricky to control it on the fly!.
I think if you want a simple looper you dont need to spend that much.

Had this a few months, hardly used it and only with the 12V power supply. Came to use it with the battery and it wouldn't twork, tried to change the battery (which was dead) and the connector came apart leaving me unable to use it on battery. Contacted Thomman Customer Srvice twice by email and they have not responded. Disappointingly poor service from Thomman and this alone would deter me from buying from them in the future.
