I decided that I liked the sound of the deeper bass after bypassing C61. So, I got rid of my temperator clip-leads that I used to jumper around C61 and replaced it with a proper jumper wire.
For the curious, here are a couple of pics. It's not too pretty. And, as you can see, there's no magic to making modifications...just dive in with your soldering iron and have fun!

I mentioned this phenomenon in an earlier post regarding "Korg's Built-In Treble Boost". This new graph doesn't necessarily imply the cause of the boost, but it does very clearly show that a boost exists.
