Ketään vertaillut muuntajia elämänsä aikana?

Tuossahan se paras on (valmistajan sanojen mukaan tietenkin) :

Valmistajan perustelut ja muuta infoa (http://www.visualsound.net/FAQpage.html):

What advantages does the 1 SPOT have over the PedalPower and other pedalboard power supplies?
1) It's waaaaaay less expensive!!!
2) It doesn't take up any room on your pedalboard and only takes up one spot on your power strip.
3) It's at least as quiet as the PedalPower, maybe even quieter.
4) It has a 10ft. cable.
5) You can use it anywhere in the world... it transforms any incoming voltage automatically.
6) It's waaaaaay less expensive!!!
7) It makes all other 9V wall-warts obsolete.
8) It can power an entire pedalboard, regardless of how many pedals you have.
9) The voltage output is fully regulated.
10) You need one.
 
Is your 1 SPOT a transformerless adapter? Does it eliminate the 60 cycle hum? I am curious as it looks the same as the "switchmode" offered by one of your competitors.
Yes, the 1 SPOT is very similar to the "switchmode", but has a longer cable (10 feet) and costs a lot less. We actually introduced the prototype of it at the January 2001 NAMM show (at the time it was called the "No-Wart"). Some German guys came by our booth and showed us their new prototype and offered to sell it to us, but obviously we weren't interested. So they went to the Godlyke booth (where Godlyke displayed a live porno "star" along with their products) and sold them. However, the Germans did take one of our flyers on the "No-Wart" and "borrowed " (i.e. plagiarized) our ad copy to use in their promotion... I guess their creative writing skills were lacking.
 
Anyhow, the 1 SPOT is a noiseless, high power, switching power supply, like the "switchmode" claims to be. However, "switchmode" is not being truthful about their adapter being transformerless and being able to eliminate 60 cycle hum. All switching power supplies have a small transformer in them, along with some high-tech circuitry. Although it is much different technology than standard adapters, there is technically a transformer in there which is the heart of the adapter.
 
Regarding the claim of eliminating 60 cycle hum, that's misleading at best. If you have single coil pickups, there is nothing a power supply can do to eliminate 60 cycle hum generated by the pickups. However, any decent 9V adapter (Boss PSA, Ibanez, etc.) has regulated 9VDC output and the voltage regulator in the adapter virtually eliminates "output ripple" in the electrical current which causes noise in most pedals. Good switching power supplies also have very low output ripple, thus eliminating any extra hum in your sound. To contrast, adapters like the Boss ACA, Danelectro DA1, Radioshack, etc., do not have a voltage regulator and will make many pedals hum like crazy despite ridiculous marketing claims like "Zero Hum".
 
How does the 1 SPOT work with Line 6 modeling pedals? Don't they require AC and use 1200mA of current?
Well, it does say "9VAC 1200mA" on the back of the Line 6 pedals, but they don't really use that. That is simply the output rating of the POD adapter which the modeling pedals also use. If you think about it, the Line 6 pedals take batteries, don't they? Batteries are DC, not AC, so the pedals must really run on DC voltage. So how do they work with a 9VAC POD adapter? The modeling pedals have a bridge rectifier at the power input jack which immediately converts AC to DC where the adapter plugs in. And regarding the 1200mA of current the pedals are supposedly using, it's really more in the range of 350mA. That's still more than an average adapter can handle, but the 1 SPOT can handle two Line 6 pedals and have plenty of juice left over for several ordinary stomp boxes. Why Line 6 didn't come out with a separate adapter for the modeling pedals, I don't know, but the 1 SPOT makes an excellent alternative to the bulky single-purpose POD adapter.

Swichmode onkin näköjään muuntajatyyppi, vaikka aiemmin mainostin, että Swichmode on hyvän merkkinen muuntaja. No CustomSoundsilta sellaisen saa, jossa lukee joka tapauksessa Swichmode. Tuossa taas on esim. Godlyke merkkinen:

Visual Soundin perusteluissahan nuo swichmodet kuitenkin lytättiin, joten kannattaa vissiin hankkia sitten "Visual Sound 1 Spot" ja siihen "International adapter plugs". Hoho.

No olipa pläjäys! Mä odotin jotain että "Boss on paras," tai "Dunlop rules." :)
 
Jepa, tosiaan tollasta minimaalisen kohinan omaavaa ettiskelen.

kaverin kokemuksesta voin kertoa että bossin pedaali ei toimi bilteman 9v muuntajalla :)
 
Oletko varma, että muuntaja syötti oikeanlaatuista tavaraa? Jos pedaali esimerkiksi pyytää DC:tä, niin se ei AC:lla toimi.

On varmaan ollut niitä vanhempia Bosseja, jotka kaipailee Boss ACA-muuntajaa eli 12v.
