I’ll admit Ive tuned it out when playing,
but in the isolation booth, with those large diaphragm gold plated condensers, every whiff & tickle of the bellows takes on a hifi stereophonic life of its own…
weve tried mic placement, even going direct.
What have others done to minimize noisy bellows sounds for recordings?
Your sound engineer should be able to capture the noise added by the bellows and remove it from the recording with whatever software is being used to record (or at least significantly reduce it).
