This is probably obvious to most of you guys, but to me it is eye-opening. I'm finally getting serious about practicing so I'm playing more advanced patterns, and I'm discovering how uncomfortable it is to play on the first few frets (at the nut). Speed is much easier up the neck, obviously. Last night I was practicing on my 4-String Jazz and I thought, "I need to be able to play fast riffs that include the low F, F#, G, etc. I just wish I could play them further up the neck for easier access." That's when I realized the value of a 5-String. It's nice when you realize obvious things. Now it's time to shop for a 5. Do 5-String Jazz basses sound good on the lower string (with decent pickups)?
