Okay... so, I know this topic has been touched on before; but, a quick search (using the somewhat disappointing TB app) has not led to a specific enough discussion of the subject... so, here it goes... I'm primarily a Fender Precision bass guy; with a Ric 4001v63 thrown in for good measure... though, I know this conversation is not exclusive to Fender instruments. That being said... Oftentimes, when reading P-Bass related threads, the talk of "Poly vs. Nitro" comes up. I have a few thoughts... but, I know there are LOTS of opinions out there in TalkBass Land. So, please share... What's your take on the "Poly vs. Nitro" debate? What are the big differences between the two? The pros and cons? What do you play and why? Was it a conscious decision? What was your choice based on? Affect upon tone? Purely aesthetic? AND... discuss!
