Thanks trevor. I might buy a new more powerful and smaller speaker when i find one (or maybe i´ll just order it online), but going again at it i found i maybe was using too much gain? turning the volume lower i could still excite the lower modes and managed to find 3 before the woofer turned too hot...

Re: A geetah in a pear tree?

that´s what i thought - cheaper than expected, but i believe it´s the plainer looking/not much figure kind of sets. they upcharge for nice figure, although i don´t remember by how much.

Re: A geetah in a pear tree?

pear wood is a wonderful, fine textured wood. i´ve never built with it but i carved a lute bridge out of it. I can´t see why it couldn´t be used for guitars (some tonewood dealers offer it). that said, if the trees are from orchards they´re probably from short growing, highly productive cultivars wh...
