Not to mention the basic issue of... needing to plug in and hook up the empeg for something as simple as tuning a guitar is going rather overboard. It'd be like heating up the big oven just to make a cup of instant coffee. I mean, it'd work, but isn't a microwave oven faster and easier?

And by the way, I forgot to ask if the guitar was acoustic or electric. That tuner I recommended is pretty much only useful for an acoustic guitar. There are even cheaper ones that will work for electric guitars.
