I have used many BOSS loopers over the years - the RC-1, RC-3, RC-30 and I am now using the RC-10R and the RC-5. I love how easy they are to use and the sound quality of these is so much better than the previous RC-3 which I upgraded from. These ones with storage are also great for saving song ideas on the fly and also for loading up backing tracks. Then there is the BOSS build quality - they last forever. The absolute best part of all the BOSS loopers though is the external switch jack. This means you can use an external button as a dedicated stop switch. This makes things much easier as you no longer have to double press to stop. I have even gotten small stop buttons built into my loopers to save space. It be great if BOSS offered this mod from the factory.
