Let me start by saying that I really like the Alembic brand CX strings (45 - 105) that were originally installed on my Spyder and Stanley Clarke Signature Deluxe.
They are bright, but not overly so, have a nice feel, a versatile tone, good sustain and have lasted several months. They are a bit pricey, but, IMO, are a good value.
About a month ago, I decided it was time to replace them and have discovered that they seem to be fairly challenging to obtain.
Considering this, are there any other round wound or elliptical wound strings that are more readily available that would be somewhat equivalent to the Alembic CX's?
