this post is what brought me to mudcat in '08.i have a d-28h sigma bought new in '87. great sound, will hold its own against any guitar.
most think it's a martin 'till they see the headstock. i'll never part with it.
however, i just got a brand new hd-28 martin for a great price.when i got home, of course i had to compare the sounds between them. when played side by side, the martin has better sound,at least i think so. but for value, you can't beat the sigma.
2 great guitars, i am a lucky man
