Most of the kalimbas I play - and consequently, most of the kalimbas I sell - are Hugh Tracey Kalimbas, made by African Musical Instruments (AMI) in South Africa.
When I started Kalimba Magic in 2005, I ordered about 200 kalimbas, and it took about six weeks from when I placed the order to when they arrived at my door.
Now, I order over 1000 kalimbas at a time, and it takes six to nine months for the kalimbas to get here. Why so long? Supply chain issues, more orders from other folks, bigger orders, exchange rate snafus, and a variety of unknowns as well.
