MusiclilyPro 80x18x15mm Bass Pickup Height Foam Self-Adhesive EVA Foam Anti-Vibration Foam for Jazz Bass Pickup, Black (Set of 10)

I mean it does what it needs too. You can stick them on the cavity or the pickup bottoms. They add a firm springy-ness to your pickups for height adjustment.

Nice and they have a adhesive with peel off fit right on my fender jazz bass pickups

This is very firm and robust. I've used these on a few pickup installations and it has worked well. Might be a bit too stiff for some projects. I had a P90 with plastic covers and thought that I could crack the pickup cover with how stiff it is. Most pickup covers are metal, so I suspect most would like these.

Better then the ones from fender.

Bought it for my cheap guitar that was not the right size for it.

Not even close to the right size. Had to cut it in half to make it work!

Works for intended purpose,but, had to be cut in half the long way as they are way too thick as shipped.

Nice and stiff and easily trimmed to size or shaved down if needed. Worked great on my jazzmaster pickups. Way better than using weather stripping in my opinion. Would buy again. But probably have enough to last a very long time. Way cheaper than getting "fender" branded foam for pickups.
