From the post

This puppy is basically another TS9, but it has clipping and gain options on "mode" switch. Modes are TS9, +, Hot and Turbo. Latter one acts as a diode lift, but adds a lot of gain. The switch is 2P4T rotary. Original unit has 250K dual gang pot for gain, and for some reason it is wired in series. So the 500K pot in its place makes this slightly simpler and the end result should be exactly the same. This sized board with a rotary switch will make it quite challenging to fit it in 1590B..

I scream, you scream, we all scream for the Tube Screamer. Pedals just don't get more legendary than this one, they don't. And if you're a fan of that classic overdriven tone used by... oh, well, just about EVERYONE who matters... there should be one mainstay in your pedalboard: this green-clad baby. The TS9DX gives you all the overdriven crunch, tube vibe, and smooth sustain that your tone has been asking for. And, in fact, with the TS9DX you have even more tonal options than the original. That's because the TS9DX is a special Tube Screamer reissue, loaded up with extra low-end crunch as well as "+", "Hot", and "Turbo" modes. It's like giving your guitar tone a swift kick in the face. A good kick in the face. The kind that makes you want more, and more, and more.
