surtout que les wah sonne mieux avec une pile usée,certaines recommandent meme des piles saline plutot qu'alkaline ou une sortie en "battery sag" ou "dying battery simulator".
En gros RMC a eu un soucis une fois sur un ancienne wah, donc il a étendu ce conseil à la nouvelle série par principe de précaution

: My wah hums with a power adapter.
A: Most power adapters are poorly filtered, if at all. Even wahs with power filters built-in can hum with some of the power systems out there.
Try adding a diode (1N914 is cool) to the adapter jack's "+ power" to the board wire . The "clear glass" end towards the jack, the end with the stripe gets the wire lead.
If that is not enough, add a 100uF/25V electrolytic cap between the + (striped) end of the diode and the power jack's negative lug. The next Q/A (below) is also of great importance. All RMC wahs already have power filtering. If your RMC wah hums then the most likely cause of the problem is an EMI source close to the wah.
NO power supply which exceeds 200mA output should be used with "new-generation" RMC wahs. This is not limited to any particular brand or style.

1. Both the 1Spot and Teese products work well, and almost all the time they work well together.
2. The 1Spot is a very capable source of a lot of clean, quiet power (relative to effects' power needs anyway). Up to about 1.7amps of 9V, if you ask for it, you got it. Over that, it decides that it's going to hurt itself and non-destructively quits playing.
3. Based on a discussion with Geoffrey,
there is a more or less rare combination of conditions where the Wizard Wah or any of the "new generation" Teese wahs can ask for enough current to hurt themselves. The 1Spot, being smarter than many adapters but not an intellectual heavyweight, says - " uh, OK, it's less than 1700ma, you can have all you want." If the adapter simply provides the current, you get thermal problems. If the adapter refuses to provide over 200ma, the wah doesn't get hurt.
4. Being concerned that his customers didn't really want smoke generators when they bought wah pedals, Geoffrey gave his customers an accurate and useful warning - don't use these pedals with any adapter that can supply over 200ma. I read his web page - the warning was accurate, if easy to misread. Near as I can tell, Geoffrey had no intention of saying the 1Spot is not a good product, only that it wasn't a good idea to use his wahs with them - or any other adapter that can produce over 200ma - in case you run into this set of conditions. If I were one of his customers I'd want to know that.
5. There are other adapters that can do over 200ma. Geoffrey's warning included those, just not by name. The 1Spot does get a lot of attention for having a LOT of available current, so it's not an unreasonable extension. Easy to misread, as seems to have happened, but not unreasonable. And I believe the Teese web site has already clarified that.

Geoffrey has already said he's on it, and has a solution in hand. I did talk to him, offered my help under non-disclosure agreement, gratis. Geoffrey chose not to accept that as he's said here; he already has a fix for this combination of conditions in the future, and I believe he will get there just fine. I will provide whatever assistance I can, although my impression is that Geoffrey is quite capable of doing whatever fixing needs done.
7. Geoffrey has been unwilling to discuss his circuits in an open forum. What's wrong with that? Shoot, ask any number of small to medium effects makers to delve through their pedal circuits in public on the net and see what they say. I like the comment from earlier. Geoffrey doesn't deserve any condemnation. He stands behind his products, and warns his customers of issues.

As for over-amperage, I think it's pretty clear - there is a set of conditions where something inside the wahs can ask for too much current to be good for them. If that much current is available, something gets toasted. Geoffrey very reasonably doesn't want to discuss the exact nature of that in a very, very public forum. I wouldn't like to do that, and I suspect that a lot of other people, if put in the same situation, would not want to either.
At least part of that is the fact that describing the conditions and circuit tells someone who's electronically adept a great deal about the circuits involved.
It is incredibly easy to get inflamed discussions going on the net over issues that don't deserve it. That's one reason I don't visit a lot of places with music and effects content - there is just too much junk, name calling, trolling, spam, and flaming to waste the time. There's nothing real under all the non sequiturs and spewed venom.
My cut is that Geoffrey has acted honorably. He found an issue, provided a workaround for his customers and has developed a fix for the issue. I don't think he's trying to flimflam or flame anyone. Let the man get on with providing the high quality wahs he's made for so many years now. He makes good stuff.
