Here are two soundbites that give a bit of an example of what each of these two guitars sounds like.
The Liberty single cone resonator on the left has a higher, more raw and metalic sound ideal for finger-style playing, while the National tri-cone resonator on the right has a more rich, bold sound with greater sustain ideal for slide playing.
Click on each of the pictures to hear what the guitar sounds like. For the sake of bandwidth, I would be grateful if you would right click on the pictures and save the files onto your hard drive and play from there. Thanks
