Glad it's not just my unit that exhibits this behaviour!
I have another unit that has dual notch filters anyway, so it's not the biggest issue. I guess it was just paranoia that I somehow had a defective unit. Still reeling after having to return a Lifeforms SV-1 due to it's scaling issues and with the 2S replacing it, I didn't want a repeat of that fiasco.
Overall, thoroughly enjoying the 2S!
