Stim boxes use a kind of alternating current waveform so there is NO positive or negative. For the "Common" electrode you can connect two red cables, two blacks, or one red and one black.

As a rule of thumb the "Common" electrode should be where you want the most stimulation. For me that's usually the glans, but if you like ball stimming better then position the common trode there. The common can be ANY electrode - a pad, a Conductive Rubber loop, a metal cock ring or a butt plug.

*Q) "What exactly is TriPhase?"


*A) This gets a bit technical. We all, perhaps incorrectly, refer to TRIPHASE when we really mean a 3-ELECTRODE SETUP. *TRUE* Triphase is something different.

A 3-electrode setup will produce two signals, one per channel. It drives current and sensation to the 'Common' electrode which can be delightful and the interaction between the two signals can feel enhanced.

*TRUE* TriPhase sensations involve the perception of a distinct third 'phantom' signal moving between the other two, achieved by having two phasing signals active on the output simultaneously. In stimming terms "true triphase" is a perceived sensory illusion working in a similar way to listening to Binaural Beat tones through headphones.

There is only one commercial stim box with an inbuilt routine capable of producing the true TriPhase effect, the Erostek ET312. However both the ET312 and the E-Stim Systems 2B can produce true TriPhase effects via STEREO audio input using certain stimfiles.

TBH I've never found 'true triphase' to be as good as the purists go on about, so personally I don't think it's worth getting too hung up about.

Didn't know if the 2B used a common electrical ground plane or if it even mattered. Interesting you can use any lead or combo of leads for the common.

Thanks again!

I can't say I've really noticed, but then I haven't compered them in any scientific way.

I could likely use the connectors from 2sticky pads and wire them together into a spare 2mm plug, but was wondering if there are other less DIY options
