Frequency-Selective Guitar Compression — PreSonus Blog

Friday Tips: Frequency-Selective Guitar Compression — PreSonus BlogPreSonus Blog:

Some instruments, when compressed, lack “sparkle” if the stronger, lower frequencies compress high frequencies as well as lower ones. This is a common problem with guitar, but there’s a solution: the Compressor’s internal sidechain can apply compression to only the guitar’s lower frequencies, while leaving the higher frequencies uncompressed so they “ring out” above the compressed sound. (Multiband compression works for this too, but sidechaining can be a faster and easier way to accomplish the same results.)

This handy hint should work similarly in Logic Pro X. I will have to try.
