I have been in a band with Richard for the past 7 years. Each mandolin he built was tried out on us to see what we thought about the sound. Eash one he made got better and better. Our banjo player has bought two or maybe three of his mandolins because of the sound and workman ship. To Him it has a better sound and any Gibson or other maker out there. If you want a great sounding and great looking mandolin please call him to have one made. You will not be sorry.

Richard Callis, RC Mandolins, are beautiful handmade instruments, each having their own wood & tone.  It’s hard to lay them down when you start playing.
— Roy W. Hare,
I have played a RC mandolin for several months and I highly recommend this maker to anyone. the Mandolin has great sound, great chop, beautiful finish and the action is very very nice. I have had 4 Gibson's, A12, F4, F5, F12 ( all great mandolins ) and I would put the RS up against any of them. Compared to the prices of the big name instruments, you can't beat these mandolins. This Guy does outstanding work. Five Star *****
