Hi, I'm a beginner bass player and I'm trying to buy a used bass. I'm considering a Kramer Baretta 422s, a Stuart Spector ns-94, or possibly a Peavey foundation or patriot on ebay if I can find one for low enough. I'm wary of buying online since I can't try out the bass. I have been able to play the Kramer and the Spector, but I'm not quite sure what to look for in a bass. The Kramer is cheaper than the Spector. The Spector is missing the saddle for the G string, does anyone know where I could get a replacement part? Any suggestions for which bass to get? Or what a reasonable price would be (used)?
