i was just searching the net, and found you can get some pretty cheap effects pedals, such as the digitech rp 70, they are only £42 so not really expecting them to be great. but i want something which has plenty of varying sounds, i mainyl play metal and punk, just seen some vids of the boss me20, is it worth paying the extra to get something similar to the boss? cheers
digitech sounds harsh and digital, and in my opinion same with the ME20. I was in your same situation and I was thinking of buying an el cheapo multi effects unit but then I'm like what the hell and bought a pod x3 live. I recommend you do the same...
