Every Pono ukulele is stunning, featuring all solid woods, and a Macassar Ebony fretboard, bridge, faceplate & tail-piece. I personally love the pairing of the timbers they use on their tops with the one of a kind uniqueness of every ukulele's Macassar Ebony bridge and fretboard.
Action and Playability
Pono ukuleles have such an awesome feel due to the ability to obtain a low string action (height from the fretboard to the strings), due to having a dual-action truss rod: an important feature that enables players to customise their playing action.
A brief tweak of the truss rod a quarter of a turn (right-tighty, decreases neck relief, lowering the action; lefty-loosey increases the neck relief, increasing the action).
Every Pono ukulele is mathematically built to ensure that the nut and saddle are the exact distance apart to ensure pitch consistency/correctness throughout the whole neck. Furthermore, every Pono ukulele has a custom hand-crafted bone nut and saddle. Every detail matters... as even a tenth of a millimetre variable is enough to have the ukulele sounding completely out of tune no matter how hard you try to tune it.
All Pono ukuleles come with high-quality Grover machine heads. Quality appointments can save a lot of pain and frustration with tuning issues. Tell tail signs of poor quality machine heads to include: a ukulele constantly going out of tune, slipping machine heads (even when you turn it, nothing happens), wobbly machine heads (when there is a mismatch between the size of the worm wheel/cog and the worm drive/spindle).
All Pono ukuleles are made of quarter-sawn timber, which gives their ukuleles unique structural integrity/strength. It also has the added advantage of reducing timber movement (expansion and shrinkage) as a result of humidity changes, which is an extremely valuable attribute for solid wood instruments. So if you're looking for a ukulele to last your a lifetime, Pono might be worth looking into.
Pono ukuleles have the perfect balance between structural integrity and wonderfully uninhibited resonance. Essentially, the less bracing (or thinner the top), the more brilliant a ukulele will sound, but will inevitably warp to one's disappointment, whereas too much bracing (or a thicker top), will disappoint in its thinness of tone, but likely never warp. Pono has mastered this delicate balance. Never have I seen a Pono with a warped top, nor a thin tone.
Projection & Tone
Pono ukuleles speak for themselves when it comes to tone & projection. Every Pono ukulele has plenty of projection, and their large range of models gives plenty of freedom to choose your desired tone.
Mahogany: warm and mellow, with rich lows
Mango: warm with sparkly highs
Acacia: bold and bright (but not overpowering), with rich highs
Cedar: mellow with sweet highs
