Locking Tailpiece Mounting Studs Posts with metric threads

I've bought several of these in various colors. They work perfectly for my projects and I'll continue to buy them as needed

I've tried Tonepros, MCB and generic versions of locking tailpiece, or wraparound bridge studs. All of them do their job of improving sustain. Both Tonepros and MCB have a thicker bottom flange which is not an issue if your guitar has plenty of clearance under the bridge, such as LP juniors or DC's. However if the bottom of your stock bridge is already close the the body, this extra thickness can prevent you from getting your action low. With both the Tonepros and MCB, there wasn't enough clearance under the bridge to get the wrench onto the lock nuts. To get around this, I tried the wood neck pocket shims to increase the neck to body angle but felt they sacrificed a small amount of tone. There are no name versions available that use a button head capscrew to tighten the caps from topside but the capscrew becomes almost impossible to loosen once it's been locked down. The design of these from Philadelphia Luthier Tools is the simplest and most versatile imo. Some reviewers mentioned that the studs rotate when tightening the cap. I made a simple tool (took 30 minutes) that prevents the cap from turning while tightening the hex wrench. I wish I could post a pic because it made my job a lot easier. I have 2 more of the same guitar that I'm adding stud locks to. One is still in transit from Switzerland but once it's here, I'll be buying more of these locking studs. Lastly, prior to ordering, I sent an inquiry to PLT and received a prompt reply that answered my question. Great customer service! Thanks for making these available!

Very high quality, improvement in tone, and stability. Bridge stays level,no more tilting.

Excellent quality, finish, & tone. Increased sustain & improved tuning stability. A great inexpensive upgrade to my Ibanez AS73 Artcore. Highly recommended.

Good studs. Holds place while cranking top nut down.

Worked great on my cheapo Galveston travel guitar. The stop tailpiece is also the bridge, which leaning forward due to play on the original posts. I recommend putting a light oil on all threads of these posts as they can be difficult to loosen during the setup process.

Fixed my issue with my PRS SE wraparound angling up, plus added more resonance being made out of steel. Highly recommended for PRS SE wraparound. I put it on a 2014 Bernie Marsden model, kept the stock wraparound bridge and just replaced the posts. Posts are better than the stock ones. My guitar is alive now.

I got a great deal on mint PRS Soapbar. The only fly on the ointment was the infamous sitar sound caused by a tilted wraparound bridge. This was an inexpensive, unobtrusive and highly effective fix. Thank you, PLT for another innovative solution.

I didn't know these existed-Ive always used washers! Found these for way less than competitors prices! I used these with washers to make a rock solid and straight bridge on my LP special! Great product,thanks!!
