    I recently purchased a Boss ODB3 and a Boss Mega Distortion and although i've read the manuals etc i still understand why they have both a volume nob and a 'gain' nob.
    Can anyone enlighten me as to what effect the gain nob has an the sound and how i should be using it?
    Cheers!
     
  2. gain is the amount of distortion/overdrive, or whaterver.

    volume is just the actual amount of volume coming out at the end of the pedal, it doesn't affect how the pedal sounds at all, just makes it louder or quieter.

    Ah right i see, so the blend nob doesn't actually effect the ammount of distortion, it just allows me to decide how much clean bass i can hear at the same time. Is that right?

    One of the little round pegs at the top of an effects pedal. They can also be found on amps, guitars and on space shuttles.

    Sorry, but that is incorrect.
     
  7. You got it. A handful of dirt pedals won't have a gain or drive knob ::cough holy stain cough::. In those cases, the way to control the gain is to increase or decrease the input signal.

    :meh: OK, a little grownup intervention here:

    Gain does not mean distortion. Gain means how much your signal level is increased going into/through a circuit. In devices that are designed to distort, like guitar amps and distortion pedals, increasing the signal level going in will cause more distortion. On pedals that don't have a gain control, you can use any other device (like a preamp/boost pedal) to increase the signal level going in, which will result in more distortion.

    The volume knob controls the overall output level, and the blend knob controls the mix between clean and distorted bass.

    Um, i've always thought of it as -

    Gain - Pre Effect Gain
    Vol - Post Effect Gain

    So set the gain until the pedal sounds like you want it to, then use the volume knob to match the volume of the pedal at 'off' to the pedal at 'on'.

    Gain affects the sound outside of overall volume. Volume does not, be sure to make that distinction.

    A distortion pedal is basically a preamp. Trat it just like you do with your amp.
