Ok, here's my question. I was just at my local music store yesterday and played this 5 string OLP MM2 that absolutely impressed me. I normally play a Fender American Jazz 4 string that I absolutely love. The OLP was $150 and I was really tempted to get it, but after playing it for a little while I realized how different it seemed to me than my 4 string. I mean, I theoretically know how to play the 5th string, and could work it into some lines, but apart from the obvious "it's just one more string" answer, I found myself thinking about the fret board differently. Like, it took me a while to feel out the 5th string, but once I did, I had to re-acclimate myself to my 4 string. I shied away from the 5 string OLP even though it was such a deal. At 4 strings it would be in my practice room by now. So...have any of you hand experience switching between 4 and 5 strings where you've played both interchangeably, and has it caused you any difficulty?
