I just slapped a Coldsweat into the bridge of my CU24, it's like the HFS only better. It has similar top end response and mid body but is much clearer and responsive, the bass is backed off so it's a bit less girthy but this just speeds up the response for riffing. It is just slightly lower output but it doesn't make much of a difference, it probably makes things stay very defined. The coldsweat makes all the settings sound a lot clearer even with the VB still in (using the 5 way switch). Now to try the Aftermath in another CU24 and to hunt down just the right neck pickup for what I like. Do know if you put a set in with a 5 way switch you need to flip one of the magnets to have the phases in the right place for some of the inbetween settings. Let me clarify on my signal chain, CU 24, Keeley Comp., Mesa Mark IV, Visual Sounds H20 chorus and delay in the loop, into a boogie recto 2x12 cab. I play mostly metal with nods towards prog, jazz fusion, and modern classical music, the new pickup works well for what I do and how I play.
