Review: Pro review-love them so far - Update: After several months of use on my all koa tenor, I can easily say these are my favorite strings of all time. They are much thicker than most other uke brands, and really bring the low mids,but honestly, to me it feels like an orchestra is under my fingers, I can get any tone I want out of them with very little effort, Previously my favorite sounding strings were Worth browns,they sound great in the studio but but they are a little low energy for my gigs (weddings,private parties, etc) and I always liked the volume Aquilas brought, but not the harshness and rattle; these are the best of both worlds to me. Just tried Worth clears, and I still like these better (although the worth clears have a heavy gauge too, I will check that out in the future). $5????????????? I guess these must be repackaged pro arte trimmings but I don't care, they're awesome, Original review: I am a pro player. I have used Aquilas and find them to be good, loud strings. But for my new koa Island Ukulele, which was strung with Aquilas from the shop or luthier, I ran into a problem where the Uke returns so much energy that the A string actually rattled on the bridge, creating a fret-buzz-like tone (I've seen a negative review of Island Ukes where the player thought they had bad fret buzz, I can almost guarantee this is actually what they were experiencing- the Uke actually vibrates TOO much for the unforgiving nylgut strings- kind of a good problem to have if you ask me. One option would be to replace the bridge with wood or another slightly softer material, but I had success using a little piece of foam around the string below the bridge, problem solved, in a slightly ugly way). And frankly, I didn't feel the spanky nylgut tone was doing the best this Uke could do. Worth doesn't make a wound low G as far as I can find, but I LOVE worth brown strings. What I may end up doing long term is buying those and finding an excellent guitar string to use as a low G, I've used Augustines in the past with good results. Or cut the nut to fit the heavy low G fluorocarbon. We'll see about that. Anyway, I tried these pro arte strings since I already use them for my nylon guitar, had never used clear nylon strings on a uke before. Holy cow, these things are thick, had to widen the C and A slots slightly to accommodate (I have proper nut slotting files). But the tone is like a big, warm, soft blanket. I really love it. I can get a velvety thumb sound, a very mellow first finger Tiny Tim strum sound, and my back of the fingernails strum is loud but not harsh. And It DOES NOT sound like a guitar, which I was concerned about. Worth brown strings also have a pleasing warm tone, but are so thin, I just don't know that they'll deliver the kinetic energy these strings do. I feel like I'm barely working and filling up a lot of sonic space. There are dead spots on the fretboard, as with any fretted instrument, but in playing chords the fundamentals are so strong the dead spots are indistinguishable. I notice another review of these strings that notes these are intended for ADF#B tuning, but I didn't notice that in any fine print, and the packaging clearly states GCEA strings (it's called a low g set after all). I think ALL Ukes probably perform better when tuned up to D6 tuning, but it's harder on your fingers for every day playing, and no client has ever walked up to me and said "golly, if only you tuned up to D, your tone would have been that much brighter, and I'd have given you a bigger tip." At any rate, I'm loving the tone and playability so far. I do notice they're taking FOREVER to settle into tune for more than than 10 minutes or so, not even close overnight after 5 days and two gigs. I suppose they act the same on my guitar, but it is taking a while, nothing like nylgut, those things stay in tune after a day or 2. Not that I don't tune every time I pick up my instrument, because I do, but these aren't even close. Yet. If my opinion changes, I will alter my review, but this this point, I am really enjoying the robust feel and the velvet fog tone these strings project (sorry Mel). BTW, one pack I ordered had a PLAIN low G in it, an absolute packaging mistake, glad I bought 2 packs. I don't think I've ever had an error from daddario before, but reminded me to ALWAYS inspect new strings before cutting old ones off.
Review: Love at first sight! - I got the titanium concert strings. They are so pretty though! And they feel great too. A lovely clear purple that has a glass-like texture that your fingers just glide on. The picture doesn’t do it justice. I’ve been exploring different string and I love the way these look and sound! They have a nice crisp and bright sound that is very appealing. They are also great at staying and tune (this could be the ukulele…) and durable too! If you are like me and have a habit of forgetting to change strings or being too lazy to do so, these work great.
