Bolt-On Neck Reinforcement Upgrade

Actually BOLT-ON your Guitar's Neck!

The neck joint on any guitar is the most important join, it's got a lot to live up structurally and tonally. If this joint is not 100% you're missing out big time.


My bolt on neck upgrade kit offers a whole load more pressure than traditional wood screws can. This means that it forces the neck pocket and the neck heel together like never before improving the "coupling" between the body and neck.


This coupling is a fundamental rule of guitar design:
Better coupling = greater string vibration transfer

You can imagine what that will do for you guitars sound and sustain! This is my favourite upgrade for bolt on neck guitars or basses

"It really has made a huge difference. Sustain is about 50% better and tone has really sweetened up beautifully. I can feel the notes vibrate through my chest while playing now

Much better definition in the lower notes eg 7th fret and below on the E and A strings" - Chris

"Before I went to Jack's, I had made do with the pasty little screws that came with my bass. They did the job, but weren't quite as solid as you might expect from a Warwick bass. Then I thought "What am I? A guitarist??"

Now my Corvette plays with the pan-seared juicy goodness you'd get from a neck-through bass! The tone is rich and meaty, and the sustain is endless. Warwick basses should come with these already installed!"

Drilling into the neck's heel. The depth and size of the hole are crucial - you need enough "bite" for the new insert to lock into but not too much that the timber spilts

Inserts are installed and driven deep into the timber just enough so the tops are just below the surface of the neck heel

The fun bit, neck is re attached and now the bolts offer a great deal more pressure meaning a much greater coupling between the body and neck. It's funny how much the neck is forced into the pocket!

This upgrade is also great of you repeatedly need to remove your neck for travel or body end truss rod adjustments. It won't wear out as the traditional wood screws eat away at the neck joint
