“Okey, many people have asked me about this but here is the ultimate answer!
First off! Grab your instrument and make sure it's good and ready to roll.
Next, go to the next mudhole you can find outside your house and water it a little bit so it gets all wet and muddy. Grab about a bucket of that and head back to the location of your instrument. Pick that up and throw it in a bathtub!
Yeah, you heard me! A bathtub. Now pour the mud all over the instrument, you might even want to add another bucket or two just in case. Let it marinate there for about 24 hours.
When that's done your almost there. Now all you have to do is plug the instrument in an amplifier (if you are using an electric instrument) and play away to the soothing sounds of the mud.”
Hmmm, hljómar vel! Ég held að maður ætti að prófa þetta!
