Hard to do? For Besley? Nah. Hold my coffee and watch how he responds....
No pressure at all........(must be getting back at me for the witness protection crack).
Anyway, to start with I have both strung with Living Waters low G fluorocarbon strings, with pretty low action (12th fret) of 0.095" for the Farallon, 0.085" for the Klos, which certainly could be affecting the tone and volume. I really LIKE the Klos. It has a pleasant tone that I would characterize as a bit mellow, and with the setup I have done it is my best playing uke by far. That said, the Farallon is louder, brighter, with more sustain, and has a more complex sound, with more overtones. Like the difference between picking up a $1500 Kamaka compared with a $500 Kala. The Kala (or the Klos for that matter) sounds quite good, and if it's the first uke you play that day it sounds just fine. But if you then play the Kamaka (or a Farallon) you just notice something a bit more to the tone. Not all solid wood ukes sound the same, and not all composite ukes do either.
I paid about $500 for my Klos, and felt it was a bargain (not sure what they cost now). A durable carbon fiber uke that sounds as good as anything else in that price range. But at $999? At that price you might expect more from the sound, and only you could decide whether the attraction of durability is enough to justify the cost. Of course we don't know if the new Klos composite neck will affect the tone, though if the neck is hollow (as with the Farallon) it ought to.
If you can afford the Farallon it is the better uke, BUT, it's also at least $500 more.
