Ok, I might just be stupid, but what is the purpose of string retainers? I'm talking about the thing on the headstock that holds down the D and G strings. I took it off, just for S&G, tuned the strings back to D and G, and played. There was no difference in having it on vs taking it off. So...? Reason I ask, I have a Fretless neck, building a new bass, don't have a spare retainer, don't feel like spending $1.80 at Warmouth + S&H just to get one a few weeks from now. I'm thinking about just leaving it off, filling the tiny little hole, and not worry about it. Is this going to be a big mistake? The only worry I had was the string slipping outta the nut, but it didn't. Probably just a slew of stupid questions. I'm starting to sound like a friggin' newbie. Well, this is the first bass I've ever built, so in that respect, I guess I am a newbie.
