Step 2Sand of Gypsies
iImage Information

This step is IMPERATIVE to this project. Almost all guitars will have a fretboard radius, be it nearly flat (12", like in classical guitars) to 7.25" on a strat. You don't want this. Pull out the electric sander, put on some 60 grit coarse, and have at it. I thought about using a plane, but the blade would get caught on every slot. You could try it sideways too, but that would take AGES. You need to devote at least an hour to this for a good job...I only put in about 15 minutes of effort, and it shows in the final product.
But to answer your question: Look on youtube, and decide for yourself. They show them with and without distortion. I personally despise the sound a fretless electric ANYTHING makes, be it double bass, fiddle, etc. It just sounds poor.
