    Hi my Little 15w valve Laney is a giant killer which is marvelous , however in our "flat" its really overkill . So I require it tamed down to sensible home recording levels ie 1 to 2 watts . it has an effects loop and a fixed 12" 8 ohm speaker , I have read about power attenuators and saw a device to put in your loop to cool the volume , (wouldnt a simple "pot" do the same in the eff loop?) dont want to spend the earth and dont want to blow the ass off my Laney , help please .

    I did the same thing with my hot rod deluxe, I have a volume box which acts as a master volume (just a pot in a box with in/out). I can crank up the preamp and get some nice crunch in the clean channel without disturbing the people downstairs. I think it might be harsh on your tubes but I have been heavily using mine for a year now and have no issues.

    Eff loop usage is a negative

    apparently Laney use a parallel loop not a series so the "pot in loop" plan wont work

    As your loudspeaker is 8R disconnect the positive wire on your loudspeaker. Connect a 10R 10Watt (or higher wattage) resistor across the disconnected wire and the negative feed. Connect a 100R 1Watt resistor between the positive wire (with the 10R on it) and the positive loudspeaker contact.
    There you now have a 15Watt amp producing around 1Watt to the speaker.
    This will enable full valve sound from the output stage without any damage and it won't upset your neighbours!
