It took him about three hours, and he carefully checked every key and tuned the piano to perfection. I also really appreciated his transparent communication. He explained the measurements before and after the tuning and clearly communicated the service cost. The piano sounds so much better after the tuning! I truly appreciate all the time and hard work he put into making sure everything was done properly. I wholeheartedly recommend Mr. Koji if you're looking for a professional and trustworthy piano tuner.

I couldn't be more grateful for the incredible work Koji did on my piano. After sitting untouched…read morefor nearly 20 years, my 30-year-old upright piano felt completely neglected and was very out of tune--to the point where I was actually hesitant to have my kids play on it. But through patience, expertise, and tireless dedication, Koji carefully worked on every single key and truly brought it back to life. It was amazing to watch the transformation unfold. What once felt like a forgotten piece of furniture is now a beautiful, fully playable instrument again--one I'm excited for my kids to enjoy. Koji was professional and courteous, which made the whole experience even better. His pricing was reasonable and upfront, as he shared a clear price list ahead of his visit. I also really appreciated how transparent he was during the process--he kept me updated on his progress and even provided before-and-after photos, which made the transformation even more meaningful to see. Koji's care and attention to detail truly stood out, and it's clear this isn't just a job for him--it's a craft backed by genuine passion. I'm beyond impressed and so thankful to have my piano--and its music--back. I would highly recommend Koji to anyone needing not just a tuning, but a true revival.

I refused (as this is a new piano). He didn't say anything about coming back with a new part to fix it. I never experienced such a behavior.

Someone took the words out of my mouth when they said Mark Kraig was the premier piano expert in…read morethe Valley. The month before he tuned our 7 foot Bosendorfer we had hired the Bay Area's most prominent self-promoting tuner (I'll let you guess who that is), and the result was a train wreck. For his high four-digit price to "regulate" and tune our piano, he left it unable to play soft notes and out of tune across the high notes. A cell-phone app can help in tuning a piano, but also takes an EAR to hear disharmony. If you're a musician I would highly recommend Mark Krag as your tuner, whom you will also find to be very pleasant and charging of reasonable prices.

First off, if all you need is a piano tune, use Michael. Michael's way of tuning is without…read moreelectronics. He uses the overtones and tunes the piano relative to itself, so it sounds correct. If you need work done on your piano, Michael is the most qualified, proficient, and reasonable expert you could possibly get. I've known Michael for 20 years, and have always trusted his judgement. My family piano is a 70 year old Baldwin baby grand. Played constantly since 1950, its hammers desperately needed replacing. Overtones were out of control. The mechanical back end of this piano had never been touched. We discussed whether to fully rebuild and tear it down- restring, and restore it. Costs were discussed honestly and candidly. We decided for Michael to replace the hammers and shanks and see where to go from there. Michael removed the action from our piano and took it to his shop, sent out hammer samples to have the hammers and shanks made custom from Germany, and with zero delay installed and regulated them. This was just the start. Michael bleached, cleaned, scrubbed, and adjusted all keys and the entire action to make it all feel like silk and move like sprung oil. When he reinstalled the action at our house, it was pretty close to dead on- he adjusted the regulation and action of the hammers, instantly NIGHT and DAY comparison in tone. Full real whole tones now sing from this glorious instrument, with the bass twice the thickness as before- I was able to go bottom to top chromatic octaves high speed with precise breaks in between all notes. Then he tuned it. Now the family piano will continue to serve for another 70 years. Next year I plan to have Michael replace the strings......

Michael quoted me for a "Free consultation" on Yelp and asked me to provide him details. It took about a week to get his partner Ken, who lived in my area to stop by for a quick estimate. Ken determined that it was nearly impossible to fix it without occurring high cost. He told me QUOTE "...there's only 2 people in Northern California who can do a legendary work like this. One is talking to you in your living room.. and the other is my partner, Mike..." Through Ken's Legendary assessment, he said it requires 4 people @$600/hr with 15-20 (really? Just for screw bolt...) he then offered $400 for my piano... I felt like Ken was trying to rip me off, so I declined his offer to part our ways. Ken came back demanding a payment of $250 for the consultation fee, which was supposed to be Free. I declined the payment, and he started commenting towards my mother of how bad of a son she had raised. Then I told him to get out, and then he started calling his wife, and had his wife talk to my mother over the phone of how rude I was of [not accepting $400 sell offer or paying $250 on a "Free Consultation"] Then I called the police on speaker phone.. and he finally decided to leave. While packing up, he STOLE 2 big bolts that belonged to our piano. Ultimately, I was able to get our Mover's insurance to compensate all the repairs.. so that's that. But Mike and Ken.... stay away at all costs!
