Hello from Madison, Wisco. I'm a newbee, and love this site. I've got my first three string (24 3/4 scale) to a point where I'm beyond my depth. I wonder if a diatonic fretless fingerboard would be good for using a slide to attempt blues but also to possibly play old gospel and REGGAE without the slide. I plan on indicating fret positions so as to be helpful when not using a slide. I have never played a musical instrument before, and know I need to start as simple as possible. May be I'll be needing more than one guitar. Are the blues fretting and diatonic fretting not the same? Also would I use the dots at all or would they be in a located in different places. Sorry if these are old questions. Thanks for any direction anyone would like to give.
