Not really a build, but with FLUX on a bit of a break for writing, I decided some cab maintenance was in order. First up was Dan's shitty marshall 4x12. It was woofy, and from past experience i determined it sounded like cab vibration and not shitty speaker. After some herbal inspiration I got the idea to coat the inside with plasti dip.
Not sure how I arrived at that, but I did it, and holy shit what a difference!
I've now coated ALL of our cabs and the sound is better than ever. Much more defined and full to my ears without any sort of woofy cab vibration sounds at all.
If you have some beat up cabs that maybe don't sound as good as they used to I definitely recommend taking them apart, looking for places to re glue or tighten up the screws, and then coat the shit out of the insides paying special consideration to all the joins and letting it seep into any cracks.
The stuff I used is available at home depo and was under $6 a can. Well worth it.
Edit: Unsure how much of a concern this would really be but I made sure to let it fully cure before putting it back together. I would not want the solvents in the plasti dip contained inside the cab as it could potentially affect the speakers glue?
