I've got lots of Stormies in all sorts of places...
But I got Mules in my 335 :)
I have been wondering about swapping around, but I really like the way they work in there.
EDIT: Haha - just followed Telerocker's link. Yep, that's my 335.
That was way before I tried Stormies.
I love the Stormies in one Les Paul, one SG, and an Explorer (that one was a surprise).
The other Les Paul has got the "modern" weight-relief chambering, and it's lighter and has "brighter" tone acoustically... a little like the 335, still a Les Paul, but closer to the 335. I bought the Stormie set that's in the Explorer for that Les Paul - didn't do what I wanted. I ended up putting Old Guards in there. They're slightly grittier than the Stormies were, like the Mules, and they work very well in that guitar.
So, on that basis, I decided to stick with the Mules in the 335. One day, I might swap the Mules and Old Guards just to see... but that's a lot of hassle on a 335!
