I just picked up some packs of the Pearl Spin Tight tension rods. They come factory fitted with Pearls hybrid snare line, however they also sell them separately.

They are essentially an expansion bolt tension rod, controlled by an allen key. They apparently lock in tuning and won't allow the tension rod to work loose under heavy rimshots with a low tuned batter (both of which I like)

I emailed Pearl re their compatibility with different snares, they replied that they will work with all Pearl snares but couldn't vouch for other brands.

I'm asking on here as I want to make sure these are ok to use with Ludwig's Imperial/Bowtie Lugs etc, whichever way you look at it there's something expanding inside the lug, depending on the drum it will be at a different depth that the tension rod sits in the lug

I've saw a guy mention on a forum about special ordering longer inserts for imperial lugs to accomodate these tension rods and make sure the expansion happens further down the lug. I'm unsure if this is necessary?

They are 32x47mm.

When I eyeball the Spin Tight tension rod alongside an Acrolite it appears the tension rod will sit deep enough in the lug casing. The BB imperial lugs might need the longer inserts?

I would love to hear if anyone has tried using them on other snares and if any mods are needed to get them to work?
