I bought this awesome pedal from @Dons of this parish a few weeks ago (who I thoroughly recommend if you find yourself doing business with him), but I’m moving it on as it’s rather too big for use on my desk when cabled up, and bought a much smaller plastic Chinese one instead. The replacement would never withstand gigging use, but does the job in my home studio. The RC20XL, on the other hand, is built like a tank and can be used for looping vocals as well as your bass, because it has a manual anmicrophone input. It’s boxed and comes with all the bells and whistles, including the manual and a very useful library of backing tracks on CD. You can use it mono or stereo and also link it to up to three footswitches – very useful add-on - using the very popular/common FS-5U or the dual FS-6.
Liran (Dons) has very kindly allowed me to use his original post and pix, as nothing has changed since I bought it from him, and I’m selling it on at the same price I paid, £70 plus postage. Collection from Mapperley in Nottingham also available, with free tea and biscuits!
I can tuck in a spare FS-5U footswitch, if you want it, for an extra £15 (s/h ones usually go for about £20 on Fleabay). I’m afraid it didn’t come with a power supply, but it uses six (6!) AA batteries, which I’ll throw in for free.
