mmmm Carvin.

I also own a Rondo sold classical guitar (Valencia is their brand for classicals) and get many compliments on the tone of the guitar. It's not a steel string, but nylon string.

It came with a Shadow P7 pickup system built in. I paid $150 for the whole shot! Those pickups sold for over $100!

Here's 'Greensleeves' that I did using the installed pickup in late 2011: http://www.pgmusic.com/forums/showflat.php?Cat=0&Number=340425&page=10&fpart=1&vc=1

They don't sell the classical guitar that I bought (solid cedar top, Shadow P7 pickup system)

With that said, I still think your best bet is to simply install a pickup in your Yamaha if you already know that guitar well. There must be a luthier in your area that can help install it if it makes you nervous.
