Re: Removing Frets
John is right about using flatwounds. Roundwounds will destroy a fretless fretboard.
You might as well try to do it yourself before paying someone to replace the entire fretboard. I converted my bass to fretless for $5 and an hour or two of my time. If it doesn't work out, you are only out a few bucks--then you can take it to a luthier.
Also, what kind of bridge is on the e-mando? Be prepared to have it to lower it a lot.
