I love my Kongsheng Mars harps, especially the models with aluminum combs. My primary gigging set now consists exclusively of Mars harps, with backups for all keys. I also keep a stock of spare reedplates in all keys. If a reed goes flat at a show, I grab a backup harp to finish the set, then replace the reedplates at the next set break. Rockin Ron's offers volume discounts on reedplates, making it affordable to stock up in advance. This level of service is vital when you're in four bands, with multiple gigs every week. They ship orders fast, too. Thanks, Ron and company!
