Build Your Own Clone Message Board

I've built a few OD2's in various arrangements, I lent my buddy two of them that were of different configurations as far as silicone vs. stock, different input and output buffers etc.

He asked if it was possible to change some components to sound more like a TS9. I've never been a huge fan of the TS9 but that's neither here nor there, it was just something he inquired about.

So that being said, does anyone have any pointers or recommendations.
