Do you know anyone with Baritone type of voice? Have you heard the voice of Carlos Marin of Il Divo group? I love this group. You should listen to their music sometime. Bass, the low frequency tone is nice to hear too. Oh, you would fall in-love to the music of IL Divo for sure.
Some of my friends have low range voices but, when they sing, it jive perfectly in great harmony. Anyway, I was browsing guitars and look what I found: ibanez electric bass and these guitars are so gorgeous looking.
