Hey there guys. I am planning on changing the tuning of my bass from standard EADG (which I learned on for 2 years, so chill out) to CGCF so I can get lower. I cant afford a five string or even a new bass, so this will have to do for now. I want to get specific string gauges, and the only way I've found to accomplish this is by buying single string sets. My strings of choice are Ernie Ball Nickelplated Slinky. The gauges Im using right now for standard tuning are as follows: G string: 50 D string: 70 A string: 85 E string: 105 For detuning, I added 10 gauge to the A, D, and G strings since they will be one step lower and 20 gauge to the E string since it will be 2 steps lower. The strings that I hope to purchase are in these gauges: F string: 60 C string: 80 G string: 95 C string: 125 I am looking for Ernie Ball Slinky single string sets in these sizes. I am wondering where I can get them. I already checked juststrings.com, marsmusic.com, and musiciansfriend.com and no such luck. I was also wondering how many of each gauge of a string come in single string sets. Is it just one, or do they give you two or three of them? Please help!!
