What level should a plyer be at before they take on these two basses. I was going to purchase a 7-string with the thought that it would force me to be a better player. I wanted to have an unlimited range to improvise with. My best friend who is one of the coldest bassists in my city, told me it would make me lazy when i play. I'm not really a soloist, so I figured 7 strings may be overkill. I've done one gig with a 6-string. Rehearsals with it were great, but at the gig, I kept forgetting about that extra string so I kept getting tangled up. i played it off well though. But since then I have somewhat been afaid of 6 and above. My attitude now is I should wait until I can do wonders with a 4-string.
