Discussion about the Korg PolySix synthesizer

C61 is a crappy electrolytic capacitor. Removing it will have a 
beneficial effect on distortion as well as increasing LF response. The 
less electronics a signal has to go through the better. Removing it also 
appears to remove a nasty click when switching between ensemble modes - 
which was the main reason for me.

Making the LF response flatter is generally a good thing. There is no 
need to make this optional. If you want to cut the bass then it would 
normally be better to use the EQ on your mixer or DAW. I would guess, 
perhaps wrongly, that most of us use some sort of EQ before or after 
recording the Polysix. It's more controllable that way and will almost 
certainly give you a better result than a simple singe pole low pass 
fixed at 33Hz. And it's harder to put back what has been taken away than 
to cut what you don't need.
