We stopped in today. It’s a little out of the way, on Lewers, just mauka of Kalākaua, thru an inconspicuous entry, and up to the 7th floor. But worth the trip. My husband is an ukulele collector, with 6 to date. Anyway, Isaac Peters is very knowledgeable and helped my husband with some technical thoughts about electronics and even uke straps. He has a selection of ukeulele brands at different price points. He is a very nice guy and no pressure, even though my husband is clearly an easy mark! He can also arrange for private lessons with various musicians. We were there about a half hour and enjoyed every minute. He also makes some beautiful koa phone cases, wish we knew what phone were getting next month.
