    I have two pedals with this control, the SS/BS Mini, and the Fairfield Barbershop. I love this option. What are some other dirt pedals, mild or heavy, with these controls?

    There are also variable power supplies that let you starve any pedal you plug them into.
     
  3. So many of my favourite pedals have bias/starve/sag controls. W&C Phat Phuk B, Southampton Fifth Gear, and many more...

  4. I love threads like this, as I think they provide a tremendous service to those looking for a specific pedal by giving out most, if not all, the options.
    (Hmm maybe I'll start that "pink pedal" thread after all.)

    So far, the thread has come up with:
    - Copilot Terra Fuzz
    - Dwarfcraft Great Destroyer
    - EQD Dirt Transmitter
    - Fairfield Barbershop
    - JHS Firefly
    - SS/BS Mini
    - Southampton Fifth Gear
    - Wren & Cuff Phat Phuk B


    It can be tough identifying the pedals that do this though, cause not all manufacturers explain what knob "x" is really about.

    As lz4005 pointed out, there are numerous devices that will do the starve/sag for pedals not equipped. However, it should be noted that some of the pedals we're discussing starve a transistor within the circuit, whereas one of the "Dead-Battery" devices starves the entire circuit, which may impact the sound negatively for some circuits. Some of the options for an external "battery-sag" or whatchamacallem:

    - Alchemy Audio's "Dead Bat"
    - Beavis Audio's DIY dying battery simulator
    I see that Danno intends to resurrect Beavis' online presence, but that is still pending. Nonetheless, the Beavis circuit and other similar ones can be found currently via a Google search...
    Series%20voltage%20sag.
    - Danelectro's "Danelectrode"
    - Gig Rig's Virtual Battery



    There are a few commercial power supplies that also will do voltage sag on one or two outlets.
    - ADL Juice Box
    - MXR Iso-Brick
    - Voodoo Lab's Pedal Power 2 Plus


    Whether you want to buy or build, I recommend reading RG Keen's article on the topic.



    Let's see some more examples, people!
     
  5. The Dwarfcraft Power Struggle is the first thing I thought of. It is discontinued, but goes between your pedal and power supply allowing you to control starve your pedals of their intended 9v. It appears to work best with analogue circuits, and there is a list of ones that have yielded best results on most sale descriptions.

    As JasonMitsch noted, these sag/starve type devices won't work well with digital pedals. Some Digi-pedals will behave erratically when voltage starved; Most digital pedals won't work at all without the specified voltage they demand; and in some cases you may even damage a digital pedal (maybe, I don't know).

    The Xotic Wah has a bias control...
    Hmm can't believe we missed the Fuzz Factory.

    There's probably a bunch of Dwarfcraft that should be added. SheFuzz...

    Feral you da man. If aliens ever show up, I nominate you to represent the internet.

    This is the proper way to do it. I find about 5 volts to be about as low as you would ever want to go, most dirt/fuzz require a bit more than that for the sweet spot for guitar stuff. On bass, we crave definition for the most part, so starving the circuit isn't always necessary.
     
  13. If? Wh...? But we GAVE you the Internet, amongst other technologies...

    Nonetheless, I am flattered.

    The Phat Phuk B appears to be a one knobber. Is there an internal bias control? I do see a bias knob on the Suppa Phat Phuk however...

  17. @TerribleLiar23 There's a number of pedals in the list that have internal bias adjustments, and yes, PPB is one of 'em:

    Man, this is the first time I've had a peek in one of these. Gorrr, lookit th' syz uv 'em caps! Mega-Mojo!


    This one was modded for external control:

    The Durham Crazy Horse has a 'volts' (starve control). IMO, it's also a really nice sounding pedal.
