Is 3 or 4 minutes enough loop time? (was: Electro-Harmonix 2880 Super Multi-track Looper )

["Gary Lehmann" <hqr@cox.net>]

From: rune fagereng asks:
And how don't you find the 3-or4 minutes looping time as limiting? 

Gary sez:
Most live loopers use small loops and then multiply them out, but then use
lowered feedback to change the texture.  Only sample and playback loop 
users
(like myself, for the most part) need loop time of more than a minute, in
order to capture an entire verse and chorus.
One of the great things about the Echoplex is its Undo feature--if your 
loop
is twenty seconds long and you have 198 seconds of loop time, you can undo
ten layers of loop.  This can be great fun!
