As I’m finalizing the research of a new supplier for the tremolo knife edge, I am faced with having to make a decision regarding how to deal with 7- and 8-string tremolos. I am getting quite a few requests for this, and it is a fun thing to be able to support. The issue is that the knife edge is by far the most expensive component I have, and I would ideally like to be able to use the same for all.
Please let me know your thoughts – I need input on whether this is acceptable or not. Durability and action is another matter that I will obviously have to deal with. An 8-string version with the same basic setup will likely require 5 springs and may feel very stiff.
