Dunlop Strap Locks: A Disappointment
I recently purchased a set of Dunlop strap locks, expecting a reliable solution. However, I was immediately disappointed by their flimsy design. The system relies on a small c-clip and ball bearings to secure your guitar, a setup that feels incredibly insecure.

My biggest concern was the looseness of the mechanism. The c-clip provided minimal grip, and the ball bearings seemed insufficient to prevent accidental release. During testing, my concerns were validated – the locks failed twice, nearly sending my guitar crashing to the floor.
Overall, the Dunlop strap locks are unreliable and dangerous. I strongly advise against using them; their poor design poses a significant risk to your instrument.
DiMarzio ClipLock Strap System: A Decent but Flawed Option
The DiMarzio ClipLock system, while better than the Dunlops, still has its drawbacks. I've used these before without issue, but my experience has shown me that they're not perfect. The design is more secure than the Dunlop, but still uses plastic components that can fail.
One of my DiMarzio ClipLocks broke at the plastic loop. While it didn't cause my guitar to fall, it highlighted the system's vulnerability. Also, the system can wear on the guitar finish over time, leaving a noticeable mark where the clip rubs against the body.
Although I've never had a DiMarzio ClipLock system fail catastrophically, the potential for breakage and the wear on the guitar finish make it a less-than-ideal solution compared to the top contender.
Schaller Strap Locks: The Gold Standard
The Schaller strap locks are, without a doubt, the best on the market. Their robust, metal construction provides superior security. Unlike the other options, Schaller locks directly to your guitar strap, offering a solid and reliable connection.
The design incorporates a clever cam mechanism that firmly grips the strap, ensuring your guitar stays put. Even if there were a failure, the horseshoe-shaped design of the locking mechanism provides additional safety.
Their superior build quality and secure design make Schaller strap locks a worthwhile investment, offering peace of mind and protecting your valuable instrument.
Conclusion: Choose Your Strap Lock Wisely
This review highlights the significant differences in quality and reliability among various guitar strap lock systems. The Dunlop locks are demonstrably inferior and dangerous, posing a serious risk of dropping your guitar. The DiMarzio ClipLocks offer a decent alternative, but their plastic components and potential finish wear make them less desirable.
The Schaller strap locks emerge as the clear winner, providing unmatched security and peace of mind. While they represent a higher initial investment, they are a worthwhile investment for protecting your instrument and avoiding the potential for damage. Given their superior design and reliability, Schaller strap locks are undoubtedly the best choice.
Don't compromise on your guitar's safety; opt for the highest-quality strap locks you can find. Invest in Schaller, and you'll never have to worry about your guitar falling.
