Best gain for input buffer

Post by Sweetalk » Thu May 03, 2018 1:32 pm

Guys, I’m designing a new hardware and want to improve the SN ratio. To do this I need to feed the fv1 as hot as possible to maximize the dynamic range and here’s my question. Since the guitar signal is so variable in amplitude, what’s the best gain for the input stage feeding the fv1. I’m aware that there’s no RIGHT answer but hopefully some experience from you will lead me in the right direction. I don’t want to use a compandor (like the 570/571 used in many designs). Any thoughts?

For guitar, I feel like 3x or 4x input gain is best. You can go higher, but you're too likely to get clipping when using a high-output guitar.
