Thank you for all the replies, just come back online and will read through them properly. (My accordion is pretty small,and is only a very cheap Hohner 48 bass...one day I will get the 72 bass Pigini I have been saving for, lol! But, it is well-loved and I play it loads so now I am trying to do some more amplified gigs, I want it to be easy to use and not to mean I have loads of problems with feedback. Thanks all, much appreciated and I will try to figure which will work the best for my situation.
