Putting foam around pickups
Here’s a little tutorial for how to put foam around pickups, like Satch techs Mike Manning and Gary Brawer have settle on every Ibanez JS used for live performance. The advantages are numerous, foam stuffed around prevents the pickups and its springs from vibrating with the soundwaves, causing unwanted noises in very high volume situations. The foam of course preserves the natural feedback and its tone quality, and finally she stops the pickups from moving around.
Equipment Necessary :
- 1 plate of acoustic foam
- Pair of scissor
- Graduated ruler
- Cutting mat
1 | Trace guidelines
Take a piece of acoustical foam, and draw a rectangle of height 71mm and width 41mm (around 2.80in – 1.61in). Draw the form of the pickups inside, the distance between the pickups and the pickup ring is about 3mm (0.12in) from the height and 4mm (0.16in) from the width, a little bit less but cutting the foam is difficult and you can easily stuffing it in your guitar.
3 | Remove the support
Then cut on the sides about 10mm (0.4in) from the edge and remove the support. You might think that you can use the support for an other pickup but keep in mind that it’s foam, not wood. The material is too soft to get precise enough for two cuttings at once, the roudings are very difficult to deal with, give priority to quality over quantity.
The aesthetic is a bit different, I used a foam that matches precisely the cosmo/chromed color of the Ibanez JS2prm but usually Satch’s techs uses a similar shade, no matter what color is the finish of his guitar. Only a few people notice that Joe’s guitars have foam around pickups on stage, usually we don’t see that unless we get close to him or maybe sometimes if you pay attention on some live DVDs, so don’t worry if you think you guitar will look very different it’s not going to happen. 😉
Many of you asked us on Joe Satriani Universe social medias to make that tutorial on so there’s no doubt it will be useful and instructive for all guitar players! If you want more tutorials and have some ideas you can submit them in the comments, meanwhile have fun on guitar and see you for other tutorials and lessons.
