    Carbon = Vintage!
    Alkaline = Modeling!
    :D

    Oh no's I never use batteries! Have i been led astray by my fancy power supply? :Ohno:

    Not if it has 'Battery Sag Controls'. :)

    I've been using alkaline in my Analogman Sun Face, but I'll give carbon a try after this. Thanks for the suggestion.

    And as I'm reading/writing this, I remembered that I left the cable plugged into my Sun Face last night. :doh:

    Alkaline batteries are also the ones prone to bleeding.

    If you have a pedal that you don't use very often NEVER leave an alkaline battery in it.

    I heard tell that Dwayne Allman used to like nearly dead batteries in his dirt pedal as it sounded better when it was starved for voltage. The only risk with that is the battery dying in the middle of a solo... :rofl:

    Basically all that article says in a reallllllly long winded way (although it is quite interesting) is that starving your fuzz pedal of a little bit of voltage will make it sound better/vintage correct.

    If you are handy with a soldering iron, for pennies you can make a little voltage sag box to adjust the voltage into your pedal (so you could use it with whatever power supply you want)

    Here is R G Keen's (GEOFX) schematic for an adjustable voltage (sag) supply. In the past I have made these & they work very well. As carbon batteries run down the internal resistance of the battery increases. This effect can be simulated by placing a resistance of say, 100 - 150 ohms in series with the supply. This resistance is shown as Rbat on the above schematic. Can be made adjustable by using a pot. The supplies under my board feature adjustable supplies, I put a 120 ohm supply resistor internally on my germanium fuzz's & treble booster's. Cheers

    Yup. I hate batteries, and using a power supply where you can adjust/sag voltage works fine for those few pedals for which it makes any difference, and has the huge benefit of reliability. It would be nice if the builders of pedals that thrive on lower voltages would build the sag right into their circuit.

    Can someone make this sag bix into a laymens term drawing... im pretty formiliar with scems but this is confusing me... id love to build something to add to my 9v 100mA out on the Ciosk DC10 for fuzz use, a perf board type diagram would be killer and i bet a few would try it if it was a little more friendly for dummies :)

    Run a standard power cable into a small box then out of that into the fuzz, ive got a battery clip cable for the ciosk but need the sag effect, or i could easily add a standard female socket onn the fuzz.

    Ok, here is a couple of PCB layouts from the GEOFX page C__Data_Users_DefApps_AppData_INTERNETEXPLORER_Temp_Saved Images_pedalbd.gif coutesy of R G Keen.
    On the left of the pic is a layout incorporating a power supply transformer, on the right side of the pic is a layout for just the circuit board where you use your own AC supply. I would suggest going over to GEOFX home page. At the upper left of the page you will see a heading "Regular Features". Directly under that is the heading (title) "FX Skill/How-To's-Schematics and More". Click on that, then go down the page to find the pedal power supply (adjustable) article. I've tried posting a link to in the past & it just gets the home page. Hope this helps. Cheers

    Edit; you need to use a 12VAC supply as the regulator needs to be supplied with a few volts more than the intended maximum output. All pedal power supplies work like this. An AC/9VDC wall wart has a transformer that outputs a minimum of 11VAC, same with 8 supply power bricks. The Weber transformer for a DIY 8 spot supply has 8 x 11VAC secondary windings. Cheers

    I think Ivan is talking about building one from scratch.

    If you just want to create a voltage sag control from your pedal supply, a simple box with a in and out for the 9v and a potentiometer is really all you need.

    eg.

    Depends on the pedal. Vintage style Wah's and Germanium Fuzz boxes seem to prefer Alkaline...

    That said, I dumped using 9V batteries years ago. I've done enough damage polluting the world with dead batteries for my FX.
