It's about time I change my strings on my acoustic and as I was looking through the list of D'addario strings and their bright-mellow chart. I was thinking of going all out and getting the mellowest strings they have, Silk & Steel strings but I have some questions.

1. How do they sound/ How long will they last?

2. Would they amplify well if I wanted to use an added pickup?

3. Are they worth it?

I've tried asking a few people and even the people at my local music store couldn't give me a decent answer so don't hate if these are stupid questions except the last one.
They're strings. Buy a pack and figure it out for yourself. It's not like your investing in a house.
