Small question for the owners of the japanese version:

I've read somewhere that these pedals were designed for the old boss adapters, which were effectively 12V instead of 9. Thus the "lack of power" and low-glowing led when using a normal 9V adapter.
The thing is I do have an adapter that can go to 12V, but is it safe to use it for the hm-2? I'd hate to fry it, you know ^^
Also, I noticed that when it's plugged to a 9V adapter along with other pedals (I have the 1spot from Visual Sound, with a daisy chain), the led is glowing brightly as it should, so I guess it's operating normally. Would there be a difference if I plug it separately using my 12V adapter?

(I know this is quite easy to verify but again, I don't want to take any risks and damage the pedal, so I thought some of you might know about this ^^)


Don't. Use the proper one. It might work butt it will slowly spoil.

Actually, you can do what he's doing. Here is an article explaining the difference between the ACA and PSA adapters.

http://stinkfoot.se/archives/726

For the lazy people, here's the gist. The ACA pedals, such as the HM-2, has a resistor in then that would take the 12v and bring it down to 9v. If the HM-2 is in a daisy chain with a 9v pedal, they share a common ground, and the voltage voltage limitations are bypassed. I am not well-educated enough on electronics to understand why that happens, but I can say from user experience that it does, in fact, work. Also, I've tried using the HM-2 with the recommended 12v ACA adapter and compared it with the daisy chain, and it makes no difference whatsoever. Just remember though that if you are going to run it with a 1spot, you NEED to have another pedal with it, which you should, because everyone should own a tuning pedal anyway.

Oh it will work all right. I'm just saying it isn't the best choice. BOSS sent some infomercial to my workplace stating to use only the PSA ones for all their products just in case.

Not really, you implied that it would kill his pedal. It won't. Of course Boss recommends using their own product to power their products. This has been a known workaround for years. Also, people have been modding their Boss Pedals to bypass the resistor for quite some time now. The mod in functionality, does exactly what daisy chaining does.

Yea having to remember to run it with a second pedal and in the first spot is a great way to fuck it up, you are just fueling the potential that he might.

Thanks for this info! So now I know that using it in the daisy chain as I do now is just as good as having the original adapter, that's what I needed :)
Also, from the article, I understand that it is indeed safe to use a 12V adapter (any, not specifically the Boss one, provided that it's regulated), but I'm not gonna try and just keep it in the chain, since it won't bring anything extra.

1spot is just the brand of power adapter he said he was using, not the position the pedal needs to be in the chain. The hm-2 could be anywhere. The only thing that could potentially happen when running through a daisy chain off an adapter is if you somehow disconnect all of the connections except for the hm-2, which at that point, your pedal would become underpowered, and you'd know right away as your tone would drop completely, the LED would dim or go off, and any other pedal you're running with it would die. If any of the other pedals in your chain aren't true bypass, your signal will die completely. Basically the only scenario I can think of where you won't notice IMMEDIATELY is if you are on stage with zero ability to hear yourself, running ONLY a tuner with true bypass and the HM-2, and SOMEHOW you manage to only disconnect the tuner. The only scenarios I can see this actually happening is if 1. someone actually unplugs your tuner from the chain while you're playing, or 2. you pick up your board and throw it across the room. Scenario 1 leads to a boot in the face, and scenario 2 is your fault because you're an ass.
