1) Can you play the same chord a guitar player is playing at the same time to add some bottom to the guitar chord? 2) What six string would you recommend with a really thin neck? 3) I know a six string is tuned BEADGC, is that the same as a guitar, I forgot. 4) A friend of mine wants to jam and she plays guitar, I was wondering, are the bass chords on a six limited compared to the guitar? The reason I ask is because she writes a lot of songs but only plays alone and I'm the only one who will be hearing her songs which are very personal and she wants me to bring my bass over. But I only have a 4 string and I wanted to be able to match her chords a little. Plus it will give me a perfect excuse to cure my 6 string GAS!
