I own/owned the following Risa ukes:
-Risa Soprano stick (sold)
-Risa Concert stick (sold)
-Risa steel string Tenor Electric (currently have)
-Risa steel string Les Paul Tenor Electric (currently have)
The Risa stick ukes are superbly made. I really liked them, but sold them because I found myself playing the steel string ones more.
The current sticks come with geared tuners, which are definitely an upgrade from the friction tuners.
Pros:
-Well set up - action is comfortable and slick
-Quality. They are very well made (Made in Europe), and the superior build quality is noticeable vs the other nylon-string electric ukes on the market (I've tried Eleukes and Stagg).
-Durability. It would be very hard to break one, it's basically a single block of wood.
-Portability. Very light and compact. Hardly feels like carrying anything at all.
Cons:
-Can't handle wound strings, which would be a bit troublesome if you want low-G tuning. You would need to use an unwound low-G.
-Passive electronics. To some it would be an advantage because you don't need to use batteries. It sounds fine plugged straight into any guitar amp, though you get some hum at higher gains. The tone is very good. A pre-amp would do wonders. It is very versatile, you can use it to get acoustic or electric sound, depending on what amps/effects you use.
-It's looks leave a bit more to be desired if you were after something fancy. Though some would argue that it's part of its unique appeal.
The Risa Steel-strings are the way to go if you want an electric ukulele that goes all the way as far as quality goes. Difficult to fault them in any way.
They come well set up, and in my view, though they're a bit expensive, they're worth it. I reckon they match the quality of electric guitars available in their price range.
They are my primary ukes of choice. I have both of mine set up with DGBE strings, because I like baritone uke. My favourite ukes of all time!
It's worth getting a Risa if you're serious about electric ukuleles, and want to get one that is guaranteed to be flawless quality.
When you don't want to fidget over design and quality issues, and just focus on the music.
