L-shape Piano Tuner Spanner Professional Wrench Square Shape Tip Tuning Hammer Tuner Spanner Tool

Perfect for what I needed to remove pins from piano.

My paster gave me an old piano that had been sitting for years and was full of mud daubers nests. I cleaned it out, but it needed to be tuned so I got this tool, since I know how to tune pianos, and it worked just fine, not only for tuning my piano, but the piano of the paster who gave me my piano.

My family piano used to play an incorrect note out of tune when I pressed a key. Now it plays the correct note slightly out of tune when I press a key thanks to this device. I only fixed two octaves and a few more keys on the low end of the piano. I ain’t messin’ with the three-string high notes using this device (I did tune some pretty alright, but man the returns are diminished at the three-string keys).I’m just a guy that can only play “Mary Had a Little Lamb” on the piano. For someone that really r e a l l y cares about their piano tuning, use a device with a longer, firmer lever or- I’m sure you know -get your fancy piano serviced by a professional. If you’re like me and just trying to see if you could fix a plain family piano, this’ll do.

Did exactly what it is suppose to.

Just got a 'free' 100 year old piano. Appears it will need frequent tuning. I am watching videos and learning how to do that.The tool grabs and holds the square pegs very well. I appreciate that the tool's hole is square -- seems to hold better. I can adjust wires with a bit of work. Very good introductory tool. Easy to get a feel for what's going on without spending a lot of money.However, I would like a longer handle. Tiny movements make significant changes to the frequency. In a few months, I'll probably spend the $50 to $80 to buy one of the longer tools for more leverage. I will also want to get some rubber plugs (using fingers works, but not optimal).

If anyone ever asks you to help them, disassemble a piano? Just laugh hysterically, while pointing an index finger at them. Then just say, NO!!! This spanner wrench is unique to removing the pins from a piano. The pin holds a piano wire in place. Each key on the piano has three different piano wires, held by these tuning pins. And it's an absolute nightmare, removing 264 pins by hand. You can jerry-rig a socket to try and use a battery powered drill, but these pins are REALLY sunk in there. And your drill is going to get a hernia trying to muscle every one of those little born-out-of-wedlock's out of the wood they're screwed into. Massive pain in the extreme lower back, if ya know what I mean. The spanner wrench worked to back those little born-out-of-wedlock's far enough, where the drill had a chance to remove them the rest of the way. Absolute pain. NEVER volunteer to help someone disassemble a piano.

I use a professional tuner for my upright piano twice a year. The last time he tuned the piano, it seemed fine. However I quickly noticed that one of the strings (each piano key has 3 strings) was slightly off. Though it was probably off a minuscule degree, it was enough to clash with the other 2 strings. I didn't want to pay $70+ for a nicer tuner, so I got this one. It fit the lugs fine. However, the handle is so short, you won't have much leverage for precision movements. So, you'll probably need a rubber mallet, too. A few light taps with the mallet and the string was in tune. This (and the mallet) are useful for those types of self adjustments. If I had to tune an entire piano with this, I'd end up smashing the keyboard to bits in frustration.

i think the tool is accurate but it seems to me that if the bolt is hard to turn on the piano the tool can't work perfectly -- maybe the bolts can take oil or something so they can turn more smoothly and get a perfect pitch

Needed to help dismantle a 70 year old upright. Skeptical it wouldn't last any time at all. Three hours later and it was still going stronger then I was!!!!!! What a lifesaver! Impressed.

Very small not possible to leveraging

Make sure of return policy as it may not fit your instrument and you have to return.

Tool works great

I only needed to tune one string which I had accidentally tuned flat and couldn't get a grip using any other sockets I own. It's tough to tighten, but the tool did the job and I can play without avoiding that note now. It would be terribly tiring to tune an entire piano, but for minor fixes it works.
