Okay, after 3 months of decision making, reading reviews, and then bottling out of spending the money, I splashed out on a RC-50 looper. Everywhere I looked prices ranged from £450 to £330. In the end picked it up of Thomann for only £260 including delivery and a nifty carry case as well!
It is very verry good, and so fun to play around with. Have just been messing around either building up soundscapes, or discovering songs with 2 guitar parts, playing one, then playing the other part over the top. Also playing the vocal melody line over the top of the rhythm guitar is kinda cool as well.
Anyone who hasn't looked into this things, they are so fun to practise with, I would recommend every guitarist to get some sort of looper (even if its just the RC-2).
My 2p!
