From the information I've gathered so far, mahogany and walnut are very similar tonewoods as far as sound characteristics are concerned. What I've read says that mahogany has a full, warm mid-enhanced sound and walnut has a similar mid-enhanced sound with the additon of enhanced dark low-mids and a brighter tone. Do these descriptions sound acurate? I'm looking for a full, warm but still bright singing tone, and both of these woods sound like they'd do the job, but I'm curious as to which wood gets more of the sound I'm looking for. My topwood is a fairly thin piece of buckeye, so I don't image that will play too large a roll in the sound. Thanks!
