I was told a few years ago by a consultant in hospital who was running me through a variety of 'allergy tests', that by far the most common allergy seen in bassists in his opinion, was that to nickel. I changed to stainless strings and allergic reaction stopped within a day or two. Just something to be aware of if you are allergic.
Unfortunately, our set has stagnated over 31 years as our guitar player only knows about a dozen numbers and they're all in 'E'. 😁 We have over one hundred numbers in the set. What he does for the other 88, God knows.
Must agree with comments above. For me at least, who is Dood, what is the 'infamous Shuker 7, and what has happened tp prompt this, no doubt, worthy suggestion?
This condition affected the best guitarist I've worked with and basically stopped him playing. He's going to try the surgery route. Wishing you the best in your journey.
