Yup, Harmony-Central is ok if yoy play acoustic or electric guitars, bass or drums. Some of the forums are fairly off-topic at this point but there are also a few good ones like the acoustic guitar and live sound forums. Lots of review resources and classifieds though. There are quite a few musician forums out there for pretty much any kind of instrument. Just google around.
Calling all Musicians out there
Audiogon is such a great specialty site that I was wondering if there is such a site for musicians to share their knowledge of musical instruments and also to advertise or trade equipment. I know there is Ebay for advertising but that can be a disaster area and forums such as this are quite fun and give a chance to get avoid certain pieces. Thanks for your help with this.
