Which power box should I start with?

You have options, and none of them are wrong. The right answer depends on your budget and where you want to end up.

Will e-stim desensitise me?

No — not in any meaningful or lasting way, and this concern keeps a lot of people on the fence unnecessarily.

E-stim doesn't damage nerve endings with normal use. What people sometimes experience is temporary adaptation — your nervous system gets accustomed to a particular waveform, which is why varying frequency, waveform type, and electrode placement matters. That's a session-level thing, not permanent. Many users actually report increased body awareness and sensitivity over time, which will sound familiar if you're coming from an Aneros or similar background.

What is "ghost-fucking" and do I need stereostim for it?

Ghost-fucking is the sensation of an electrode appearing to move inside you on its own — thrusting, pulsing, and shifting position without anything physical moving. It's created by the signal, not by motion.

No, you don't need stereostim for it. Pulse-based devices can produce this effect too. But electrode quality and placement is everything — cheap pads and loose contacts give you surface buzz instead of the deep, moving contraction that makes ghost-fucking work.

What electrodes should I actually buy?

The negative reviews on Coyote's own electrodes are mostly valid — contact consistency is hit or miss and the sensation tends toward surface buzz rather than deep contraction. The 3.0 rings are better but still not the top tier for serious play.

For insertables, the undisputed benchmark is E-Stim Systems. Their precision-machined aluminium line — the Moaner, the Tripler, the newer MWCBP — delivers even, consistent contact with full conductivity and no material degradation. Don't treat these as a future upgrade — if ghost-fucking is the goal, they're the right tool from the start.

For cock rings and loops:

• ▸
  Conductive rubber loops — cheap, forgiving, good for early experimentation.
• ▸
  Joanne's 3D-printed loops — highly recommended by the community. See where they fit and feel nice before committing to metal.
• ▸
  Solid metal rings (e.g. the ElectroRing system) — excellent feel but sizing matters a lot. Order a sizing kit first and measure both erect and flaccid before buying the real ones. A ring that fits erect but slides off flaccid (or vice versa) is useless.

What's "triphase"? And is audiostim really the best approach?

Triphase is the effect of stereo signals crossing through electrodes that share a common negative return. The physics is endlessly debated and above most of our paygrade — but it feels great, and it's a big part of why audio-driven stereo boxes have become the community standard.

Is audiostim the best? Arguably yes, compared to what came before it. But this is very new territory. The emergence of FOC-based boxes in the last year or so has genuinely shaken things up — that fact is now up for debate. For audio-based play specifically, the community has been focused on audiostim since discovering input-based driving, and built-in box programs are rarely used once you experience what audio input can do.

Short version: if stereostim is your destination, audiostim is where the action is right now. If you want the cutting edge, keep an eye on FOC developments.
