So recently I needed to replace my 8 string bass strings, take off that low F# and add a high A# instead, and I had no idea where to go until I found these guys https://www.circlekstrings.com/store/ Their string gauge chart was really helpful and they made it easy to get a balanced set for my instrument! I would recommend them to anybody! Their shipping is fast even on the cheapest of shipping options and all the strings are thoroughly labeled. If you need ERG strings, go to these guys! Has anyone had a bad experience with them? Thoughts? Opinions?
