I didn't get any bites the first time, so I wanted to ask again, does
anyone have an opinion on the new Korg PX4D guitar/bass trainer?

I purchased the unit because I wanted a single unit that I could use
for both guitar and bass, but I'm returning the PX4D because its
performance isn't very good in comparison to the old PX3B. I have
found the PX4D to be so noisy it's not suitable for recording, and the
Aux function does not record phrases as clearly as the old PX3B. In
my own opinion, Korg has taken a step backwards with this one.

Anyway, the reason I'm asking if anyone has an opinion on this
product, is that perhaps I could consider that I've gotten a lemon and
the possible solution is an exchange.

Any responses are appreciated.

Mark
