Thanks for the advice. I somehow thought that 5 would be better than 4 and 6 better than 5.
The NS EU6 is so low in action, it's almost cheating. This takes out one big stumbling block out of the learning process.
More strings does add to confusion but the end result was actually good. I finally learned the fretboard! The approach notes were so difficult I had a hard time with the simplest notes, going from F7 to Bb7 to Gm7 to C7. I was thinking, how difficult could it be to go from an F to Bb to a Gm to a C. Boy was I wrong. After 2 days, I figured out that I just didn't know the fretboard. I couldn't visualize the notes above, below, 2 above, 3 below, etc etc .
It literally took me 4 months to memorize the fretboard to the point that I could actually use chromatic, dominant and scale approach at the most elementary level.
Now that I have the EU6 with me, I have to intonate the notes on top of learning new technique. Since this thing was so expensive and takes up so much space, I'll be sticking to this one for some time. LOL. Anyway thanks for the advice. I'll try to snag a cheap 4 string Stagg sometime soon to learn according to the textbooks since they are mostly written for 4 stringers.
