These blocks have become my go to. Ive just installed my 3rd block. All 3 guitars had very different natural tonal characteristics. As far as tonality these blocks seem to react differently with each guitar you install them in. They seem to pinpoint exactly where your guitar is lacking or overbearing and brings out the best in it. Its almost unbelievable what these blocks will do for tone. Sustain is not lacking with these blocks either and they are very resonant. I as never really fond of the brass and was highly disappointed in titanium. I will be using Stone Tone in all my Floyd equipped guitars from this point on. See for yourself!

I emailed the company with interest on their products; I received a personal phone call from the owner of the company where we discussed my thoughts, expectations, options, and other upgrades I planned on doing to my guitar.Robert made a personal recommendation that was tailored to exactly what I would need. He also included tips and other ideas as we discussed my purchase. I was kept in the loop on shipping times and manufacturing lead times and my product showed up exactly as described was super easy to install, and I am overall extremely satisfied with my purchase. I now recommend Stone Tone tremblocks to everybody.

Put this sustain block in the guitar in the photo. It is definitely a good upgrade. It adds more sustain, and harmonic content while not coloring your tone. It seems to allow the tone wood to resonate on a higher level. Big fan highly recommend stonetone.

Just wanted to say a massive thank you to Robert Belardino Disanto for installing your Stone Tone Rock Block! I’ve been using it for a week now, the tones that I’ve been getting from it have made my guitar come alive. Everything from the acoustics to the harmonics have changed to a brighter and a much cleaner tone. I highly recommend to anyone that plays the guitar to try out Stone Tone ProductsIt really did make a significant difference. I play guitar for Vibe and TOUR and my tone has never been better, I don’t know how I’ve lived without it!

I use a Stonetone 37 block.And I heard it the second I tuned the guitar to pitch without even plugging it in an amp.If you are curious about these blocks you will not be disappointed. It makes electric guitars sound and play better. Its something you have hear and feelIt has helped my guitar playing and that’s all I’m looking for. To each his own.Cp

Amazing product!!As many Floyd Rose users i had always find the need to improve the sustain and tone of my guitar.After installing the Stone tone rock block in my guitar i never looked backWhat an amazing product it really changed my life, now i can have the tuning stability and amazing tone!!!!

Stone Tone are the ONLY blocks Ill use on my Floyd Rose guitars! Nothing gives your tone more body, or upper harmonics like attaching a piece of solid granite to your bridge. Plus theyre made with pride and craftsmanship right here in the USA. Highly recommended!

I’ve ordered quite a few of these blocks including a custom made. The blocks do what Stone Tone claims which is what led me to custom order one and buy 4 more, the quality and customer service and knowledge Rob has is amazing and I highly recommend you get one for your guitar. 🤘 Customer for life!

Stone Tone Products are amazing! As a guitarist, every year there are countless products put out that claim to be the Holy Grail that weve been searching our entire careers for....Rarely ever coming near the hype in the advertising. When first introduced to the granite sustain blocks for Floyd Rose I thought to myself the only thing this will do is make me able to say man now this guitar really rocks! But audibly not much more. I couldnt be happier to admit that I was way off. The science behind them is definitely impressive, but hearing is believing! The improvements in gain acoustically, before you even plug into an amplifier, are unmistakable. The improvements in sustain and tone are immediate as well......you can actually feel the vibrations are stronger than ever. Then amplified.......wow. Never have I felt that a product completely meets and exceeds the claims made of it.I wont own a Floyd equipt guitar without a Rock Block now. Im a Stone Tone junkie now. It doesnt matter why or how it works, it just does. Whether active or passive pickups, exotic tone woods or not, you WILL hear and feel improvements throughout the entire audible spectrum after using any one of the products offered by Stone Tone. You wont be disappointed

Stone tone blocks are the best upgrade you can do for your guitar, It makes every note articulate and really stand out.

I’ve been in the calibration and measurement field for nearly 25 years now, and have quite a bit of experience in the audio engineering field. Having said that, I am very skeptical when it comes to claims such as the ones that Stone Tone makes, about new products, that seem to perform miracles, the kind of claims which every company in business make nowadays, but I have to say, this technology and this product are as absolutely legit as it gets ! In my profession, we use hardness testers and surface levels that measure the tiniest fractions of a single degree and that kind of precision and technology is what is being used here to aid in the transfer of sound waves through objects as accurately as physically possible and the end result is a an amazingly accurate output that was just not being utilized before now !!! Just like the woodwind family, specific density and composition of material is carefully chosen to customize and fine tune a unique sound by the composer and this process is very similar and has the same effect on sound waves and is a new and different tone or mood on the end product. I’m not paid or given anything by anyone to endorse this product, I just honestly can’t stop talking about how brilliant the concept is and how true the hype is.

Stone Tone Blocks are an amazing American Made product! They do 100% of what they advertise this product to do! Far more definition than any brass or other man made products of the same nature! Stone Tone is also a big supporter for our Veterans and our Military! They have donated many of their blocks to help fundraising for my 501c3 Non-profit Organization SGT SHREDDER ROCKING TO HEAL VETS INC! They also have been active in helping us to meet many major rock guitar and music industry icons for support for our Veterans as well! Stone Tone is amazing and 100% American!

When I first tried the Stone Tone block I couldnt believe how much difference it makes. Perfectly built, it adds sustain and harmonics to the guitar in a way I never heard from any other Floyd Rose block before. Even the feeling of the strings changes, its like if the strings pop and have some energy, some sort of life for themselves and you can feel it in your fingers. After you try this block you definitely cant go back. This is definitely one must go upgrade for any Floyd Rose bridge.

Since I was introduced to Rob back in 2013/14 at Namm, Ive had an issue not owning a Rock Block on any my trem guitars! The difference is real! Warmer tonality, better sustain, an all around upgrade from the standard brass! Highly recommend checking this thing out!

Great product! Noticed a big difference compared to the stock block, great and inexpensive upgrade. Will definitely upgrade the rest of my guitars with stone tone blocks.

I have been and endorsee of Stone Tone music since 2005. Robert and Company have been nothing but a blessing to my career. Roberts technology is something that will continue to Blossom. You will soon see Stone Tone products in every guitar. Be one of the first while you can.

All of the tone, none of the weight. This is the mod I never knew I always wanted. To my ear it reduced some of the harsh high frequencies and tightened the bass frequencies, while keeping the fundamental and the muscle. As an added bonus it made my guitar lighter as it replaced a rather heavy brass block.

Ive been a huge fan of Stone Tone Floyd Rose Toneblock Upgrades since the first time I witnessed the huge difference in bandwidth and sustain that is only offered by Stone Tone. Other materials offered by other upgrade companies only cover the same spectrum incrementally, and I dont know about you, but my guitar only has room for one tone block... Stone Tone!

Great products highly recommended Ive had nothing but great results with the stone tone block. I highly suggest this product to beginners to the pro I have been using them for years very happy with the performance and tone of this product check it out for yourself you can thank me later 😆

Great products and have installed the blocks on 5 of my guitars! Highly recommend if you want to enhance, strengthen, and sustain your sound!

I cannot believe the tone change it has mad tl all my Floyd equipped guitars. Tone is more percussive, smoother, lows are tight miDS are more pronounced and highs are smooth.Brass is harsh and does not give you the tone of the Rock Block

The granit block really made a great improvement in the resonance and tone of my beloved charvel guitar!Dont hesitate and get yourself a stone tone block youll love it 🙂

After using the Stone Tone Rock Block on my guitars I am a firm believer in this product, it adds more sustain, punch, cut, and articulation in big chords. Aside from a wonderful product their customer service is hands down the best.

So glad about being part of STONETONE.. omg the difference is night and day... viper guitar stonetone rock block vs ibanez prestige with stock block//// recorded.. both have bareknuckle nailbomb pickups.... VIPER crushes IBANEZ by a mile!!!check out stonetone rock block... makes your guitar growl..🇺🇸🤘

This is easiest and quickest way to improve the tone of your guitar. I have rock blocks on eight of my guitars.

You cant go wrong with a Stone Tone Block, bought one for my San Dimas and it brought out the guitars full potential. Amazing sustain. Looking to buy 3 more for my Nightswan, Kramer 84 and Evh Stripe. Buy it, you wont be disappointed.
