I LOVE the R.Y.'s in my Jackson V's, Korina and Mahogany neck-thru guitars. The R.Y.'s are fat, big and "growly" in these guitars.
But, I found the R.Y. to be a bit too warm in my old 1970 LPC.
I installed the Cold Sweat (ceramic) into the LPC instead, and that was it. The LPC sounds tighter and with a faster attack vs the R.Y.'s.
For LP std, the story seems to be another. I might get another pair of R.Y.'s into my '68 LP (converted form P-90's to 'buckers). So far a set of Tom Holmes is ok, but time will show. 8)
