| The other night a put very fresh battery into my recently acquired CE-2 and wow! - I have never heard it sounding better. I have heard it said that one can never do better than a battery in these devices (for clean power) - is that true, een with the purpose-built Boss adaptors? Why? Is there anything I can do (i.e. build some special whiz-bang power supply?). |

Even better is their characteristic output as the battery drains as opposed to a constant source like an AC adapter. Using batteries can sometimes give you a tone much different than AC. Think of analog vs. digital or tubes vs. diodes.  |

Danelectro sells "vintage power" batteries how about that for a marketing ploy? |

I've heard that before too, half-dead batteries warm up the tone in some pedals. Like overdrives and distortions, even some fuzzes.
Also have a Dano battery kicking around, I assumed the 'Vintage' was part of the reissue series. Probably Dollarstore batteries would do the same, being cheap and all.
Like most, I too run my pedals on an Boss adapter, too much hassel to unplug them all after. Tho it would solve the ASA problem of having to daisychain some older pedals. |

What changes as batteries weaken, voltage/ current/ both?
Just out of interest I put a multimeter on 8 batteries I had the other day, 6 Duracells and 2 Roland batteries.
The Duracells ranged from 8.3 to 10.0V, and the two Rolands (one new, one slightly? used) were 9.6 and 10.3V!!!
Is this unusual, does it mean anything? |

| Voltage I believe, which is why a switched power supply provides constant voltage even if the input wavers. Step in here Bob... |

So..couldt we not just "put" a resistor between the battery and the pedal and by diong so, lowering the voltage to produce a more warm sound?? I know there is som psu�s with that special function.

I've heard of people using voltage switchagle AC adaptors and the running it a lower voltages to get a different sound. I'm not sure if that good for pedals but I guess it simulates a dying battery!

The Voodoo Lab Pedal Power 2 is a universal power supply for all battery-operated guitar pedal effects. New features include two outputs that can have a variable voltage "sag" to emulate dying carbon batteries.

New 9V batteries usually measure about 10 volts and maintain a consistent voltage and current flow until they start to die. A wall-wart AC adapter will usually be closer to 12 volts and it is subject to voltage fluctuations the harder it has to work. For example: if you have a few pedals hooked up and you slam an E chord ala AC/DC, the initial attack of the chord will draw a lot of power from the AC adapter and the voltage will temporarily drop.
Pedals that are dependent on picking dynamics (distortions, OD, pre-amps, etc.) are particularly sensitive to voltage fluctuations. When the voltage drops, there is less headroom for the signal and clipping will occur earlier (and usually sound more ragged). This can sometimes be a good thing which is why some people use old batteries in their distortion pedals.
Effects that are based on delay (chorus, reverb, flange, and, um, delay) need consistent voltage to accurately reproduce the sound, so they sound best with fresh batteries. |
