hag said:seems he's got a pedal which loops between 4 and 5 seconds... thought somenoe might know what they were... or maybe suggest something similar.
my digitech x-series digital delay gives you a 4 second sampler mode
hit the button and play something, hit it again and it starts too loop what you've just done
hit it again, while yer loop is up, and you can 'overdub' another part to that loop again and again and again and again and again and again and again...
it's not perfect, but for the money (150) it's aces compared to splashing out 600 or so on a proper dedicated pro looper unit.
