Never had strap issues until I got a mando with a built in pickup

[dang]

I have been playing mandolin for 15+ years and I have felt lucky to never encounter any of the dreaded issues with a strap falling off of the end pin. I have read some horror stories here on the cafe and have seen the solutions that people use but it never really was an issue that was anywhere but in the back of my mind. A couple of years ago I ordered a custom mando with the tailpiece drilled out for a pickup, I had been using a schertler and a few microphone configurations and a built in pickup seemed like the logical solution to the whole amplification problem.

With the pickup the size of the end pin that the strap needs to hang on is significantly larger then the usual end pin I have been used to for years, so my usual strap (a rather thin levi's) doesn't really work all that well.

I had read a thread (that I can't seem to find now) about a similar issue and some solutions people had used and I stole an idea - or adapted one - to tie a small piece of leather shoelace to the end of the strap and then tie this around the endpin so that I could fit it around the larger metal end pin. Kind of an adaptor. Worked great for months...

Then last night it came untied 5 mins before it was time to go on stage. Super small audience, less then 100 people, I was only helping a buddy play a few songs so he wasn't alone... but I felt like an idiot tying my mando on right at that moment.

So I was hoping someone could tell me the secret knot that doesn't come undone? Or how to enlarge a strap button hole in a way that isn't just "cut it larger." Is there a certain size leather punch to buy? I think I am going to have to go for a wider strap then I have ever used. Any input would be appreciated, looking for a pretty solid solution, I would have hated to have that come untied while I was on stage!

Use a square not, it should be fine. By the way, that would be the Hans Brentrup method.

I bought a set of punches years ago that work in leather, plastic, etc. I use them to enlarge holes. It is like this one:

The 3/8" punch in this set worked fine to over punch the hole in one of my straps to fit a pickup end jack.

Sully straps will retrofit the tab on a Sully strap to fit an end jack perfectly for the cost of round trip mailing. I believe he uses a 3/8" hole as well

Leather lace from Tandy, loop it around the scroll with a running bowline, use a hangman's knot for the button. Will last for years.

I use a tapastring endpin: that's a regular size endpin with a very rugged 1/8 jack. So an ordinary strap will do.

(A super small audiance for me is smaller than the band

Just another example of what Mike showed above. I use this on EVERY mandolin I have!

+ 1 for adding a short safety loop that ties the end of the strap (through a hole) to the tailpiece (by running under and around it), just as shown in the photos above. You can never be sure when your strap might slip off the tailpin, or if the tailpin itself might slip out of the mandolin altogether. This little safety loop will catch everything if either of those things should happen, preventing disaster. You can make this loop from paracord, leather, a shoelace, or even a bit of flexible wire. It's the best insurance you can have to protect your mandolin! It has saved mine at least a couple of times, and I don't know why everyone doesn't do it.

I have used a couple of Bailey Straps over the years and won't consider getting any other strap now. My end pin has come out, but the strap has never come off!

If you are playing plugged in the strap won't come off, you can also put a drop of superglue on the knot and it will keep if from coming untied.

I enlarge the hole with a leather punch that is like a pliers with several hole sizes that rotate. I use the largest one and simply nibble around to get it a snug fit. I have never had one come off, they are tight and hard to get on, but once on they stay on.

3mm leather cord with a hangman's knot is how I attach all my straps now. I have never had a problem with this solution since it is self-tightening with the weight of the instrument.

I use a Lakota Leathers strap over a K&K endpin, and I really had to struggle to get it on the first time, but now it shows no intention of ever coming off. Fine by me, as I store it with the strap on any way. My problem has been a tendency for the screw-on portion of the endpin to un-screw itself. I've been meaning to put some threadlock on it.

I've used a Dunlop strap lock to prevent unwanted release

Thanks for all the responses, not sure what I am going to go with yet but I will hopefully come to a decision soon, I will post what works for me.

I have also noticed this happening and wanted to throw that in at some point also, thanks, seems like a good solution.

You need the StrapKeeper.

Thanks,
I was kind of hoping for something easy like this, I've got a couple of these on the way, I'll post an update when they get here.

I use a slip knot on my end pin and it does not come off.

Here's the knot though for tying two strings together. It's not a square knot! (It is the knot I use; however.)

Ok, I have had the StrapKeeper on my mandolin for about a week and it really fits exactly what I wanted it to do. It securely fits over the larger endpin with output jack and allows me to use the same strap I have been using for years. Solved the problem so well I bought a couple of extra for my guitar and tenor guitar. Saved me the cost of buying new straps and the straps are now secured better then ever. Also saved me the worry of modifying a couple of rather expensive straps by using leather punches. This wouldn't have been hard but I haven't had all that much luck doing modifications over the years, my dabbling in hot-rodding and amateur lutherie are over. I admit I need professional help

Thanks for all the advice, cafe members are awesome

If you have a soft strap, this method works really well. Not suitable for hard leather, however.

Rod from Pinegrove Leather (where I bought several well made straps) offers a nice solution for an endpin jack, didn't use it myself though:
