  • Nickel Plated LIMITED EDITION 

  • This is a hand crafted boutique MADE IN USA sustain block manufactured from exotic steel JUST LIKE THE FAMOUS 5150 PROTOTYPE BIG BLOCK. It also has the identical size and shape and girth as the original prototype sustain block.

  • The AXN™ Model-84' sustain block is made from a steel that embodies the same tonal characteristics made famous by this first version Prototype Floyd Rose sustain block. Its also virtually the same alloy as the sustain block used on the VH recordings.

This is a hand crafted boutique sustain block. Manufactured from USA metal and Machined by hand at an aerospace machine shop in California USA. It can be mounted to your Floyd Rose tremolo and will fit into your guitar with NO modifications to your guitars body. Its a drop-in replacement for your stock Floyd Rose sustain block.

We employ 100% American engineering and experienced American machinists and craftsman to produce ALL our sustain blocks. This costs us much, much, more yet we know by testing that the performance and tone is well worth the cost. We use our proprietary steel formula. The AXN™ Model-’84 sustain block is machined to adhere to our exact specifications which we replicated from the original PROTOTYPE Big Block.

We are a small company offering a unique line of products made in small quantities. We have extensively field tested exotic metals used in guitar hardware.

We are the authority on early 1980s vintage locking tremolos and the evolution of those including the sought after tone produced by the manufacturing processes of that time. We analyzed the Original Floyd Rose Prototype Big Block and used that data generate a magnificent formula for each AXN™ SuperWide™ Sustain Blocks! Do the research you will find AXN™ Guitars the authority on Floyd Rose History.

For those of you that are after the brown sound, or lets just say the true franky flavor this sustain block will get you there. Years of sampling, testing and R&D is over. Our first batch of Model ‘84 sustain blocks was delivered in 2016 with great success. This years 84’ is refined just a little more.

No one has done the proper metallurgical testing. True results come from spectrometer, digital microscope and hardness testers. Our AXN™ Model-84' Steel Sustain Block takes from the heritage of the original and gives it to you in a perfectly designed modern sustain block that is ready to mount on your modern and vintage Floyd Rose tremolo. Its weight, girth size and design specification deliver a Floyd Rose Experience like no other.
