Putting a capo at the first fret would be confusing to me, because everything is one fret off from where I'm used to playing it. It's really not necessary to use a capo for this since he can retune all the strings half a step and then not have to relearn anything. You really don't need to adjust the setup for a half step difference, so retuning is all that's required.Yes I understand how capos work..... so how is this not the easiest approach? If you need to buy a whole new bass for bloody Eb, you must play it pretty frequently - so why not tune to it and capo up to E when needed..
