    Hi all,

    I went in search of a noise gate and settled on a Boss LMB - 3 Bass limiter Enhancer. (It was a toss up between that and the NS2. LMB3 won because I found a cheap one and couldn't work out the practical difference between the two).

    Bought it second hand without a power supply. Sticker on it says "Use Boss PSA adaptor only" which Im guessing is the equivalent of "Use only AJAX brand cleaners in your westinghouse washing machine".

    If I buy a boss one Ive got to order it in. If I can use a generic Ive got plenty lying around.

    Can I just use any old 9V adaptor or do I need a specific amp /ohm /rad ratings? If so, whats the best?

    Not batteries. Hate the batteries. But don't want to fry my new stompy.

    Thanks!

    any center negative 9v power supply should do just fine.

    The LMB-3 isn't a noise gate and is actually capable if adding quite a bit of hiss, but hopefully you get the results you want.

    Definately check out Bongos FAQ.

    The LMB is a good pedal but not good for eliminating noise. In fact, the 'enhance' knob seems to be volume control for a noise generator.

    Cool! I get to buy another pedal :D

    Anyone used an LMB3 and an NS2 in combo?

    Where is your problem with noise coming from? Maybe a pickup/bass upgrade would be a better use of money?

    Noisy power, mainly. Plus there's a few laptops around my house and they all add buzzzzzzzzzzzzzzzzz

    Also have a bunch of cords that seem to pick up everything from Fox Sports to Voyager Satellite transmissions. Just bought a nice Klotz as my main but forgot patch cords to go from the stompy to the amp. Doh.

    And at the end of all that...have a few el cheapo copies that I love to take out once in a blue moon and give a good pounding. Lots of disconnected earths.

    Maybe a better power supply is a good option then

    Funny! He just meant the bit that the pedals plug directly into, not the supply for the whole district. :p

    Domestic power outlets seem to carry loads of noise as a rule - fridges, TVs, laptop power supplies all sing their songs through the wires.

    Hahaha. Not what I meant lol. :D

    I meant a Regulated Power Supply like a One Spot might help get rid of the noise.

    (I'm not exactly an electrician so I don't know the specifics of this)

    And all of that noise is supposed to stay on the ground path, away from the audio path. Your job is to learn the methods of isolating them. :)

    This.

    Dirty power can do more than just cause noise. It can fry your equipment.

    NOOOOOOOOOOOOOO!!!!!!

    OK Im here to learn. So what do I have to buy for clean quiet lectrikery? Some kind of electricity scrubbing device / USP / regulator board? I need to plug in my amp, my pedal/s, & my Apogee. I assume its something that should be part of my standard setup whenever I play.

    (Ive got to admit, despite the noise I've been in this house for a long time and nothing's gotten fried except a dodgy e-bay laptop supply).

    I see what you mean about adding noise. That little enhance dial can turn a background hum into a screaming Sputnik.

    But Like Wow, does it add some boost! Punchy little bugger. I certainly haven't wasted my $45.

    It's a very good pedal for the cost. Just turn down the enhance.

    Like others have said, the LMB3 isn't a noise gate, quite the opposite. Any adaptor will do, like a OneSpot, but I got quite a bit of hiss from mine until I started using a DC Brick to power my board.
