Hello!
I've got a problem with my LM-2 Limiter (AB32374, April '90) that I bought at eBay a few days ago. The pedal arrived yesterday and I tested it in the evening and with clean Stratocaster playing it worked really fine. But then I added various distortions after it in the chain and then I regarded how noisy it works. Too sad! I just made a sound file so you can hear it, too:
www.pepemusic.de/lm-2.mp3
Pure effect signal! No guitar connected, just a non-powered PW-2 before it. At first you hear the XT-2, then the LM-2 is added, switched off, XT-2 switched off, LM-2 switched on and finally off.
Of course I set the volume to nearly maximum. I just also tested it against my LMB-3 without enhancing the sound and that piece was nearly as quiet as a fish in comparison to the LM-2.
I used a BOSS RPW-7 half rack power supply and a daisy chain for powering the pedals and the noise of the LM-2 also appears, when I use it with batteries!
Is this a known problem and how could it be solved?

| Welcome to the forum.It sounds like the caps are kinda old in your pedal.I wished you could of tried it out but that's the problem with ebay.Most boss pedals can be noisy. i would say live with it or replace some of the poly film caps with some metal film caps that will get rid of some of the noise.Since i am assuming that this pedal is causing all the noise since it is new to you |

Thanks for your fast replies! The pedal cost me 31,70 Euros including shipping! And it included two Behringer DI-Boxes as well - so I really won't complain!
The pedal itself is rather noiseless? That would be just great, because it would be so useful in my guitar effects chain. I'll see which capacitors should be replaced. Could it be visible through copper rust which ones are faulty? I'm not the best guy when it comes to soldering - I just wanna play!
Thanks for your compliments about my site. It is far far far away from being finished. There are lots of pics that are waiting to be placed in and I have planned too much for it so that my little amount of free-time is not enough at all... |

Welcome to the forum PepeMusic, from Phillytown, USA! If you are going to replace your electrolitic caps, you should replace them all. There's really not that many, at least not as many as I replace on late 70's early 80's radios. I've seen them drift by more than 30%! These radios perform like new afterward. A great way to practice and improve your skill is to get one of those copperclad circuit boards and solder and desolder some caps. You'll quickly learn how much heat it takes to use desolder braid or a vacuum bubble. Let us know how it turns out! |

I gave the LM-2 to a friend on sunday and he gave it back to me this (or better said: last) evening. He changed the six eloctrolyte capacitors and now the noise has almost completely disappeared! 
It still makes a certain noise, but only when set at a much higher volume level than before. I couldn't hear the noise when I played without distortion a few minutes ago and my multi effect pedal was set to absolute maximum input and output levels! My FZ-2 rumbled like mad when I first tested the Limiter last week. Now it's just a bit noisy when I turn the Fuzz gain to 2:00h or so, but that's okay! If I need high gain distortion I can switch off the Limiter. Limiting before high gain distortion doesn't make any sense to me anyway. |

well limiting after a high gain distortion makes even less sense.... (generally speaking - and from my post in the non-boss-gear-discussion forum you should know that that means: less is the new more).
A high gain distortion IS a limiter.
a limiter or compressor after a high gain device will always increase noise a bit - at least when the limiter or comp is set to unity gain.
Glad the caps solved your problem for the most part though

I just played my Strat to test if the BF-3 increases the signal level and used my LM-2 in front of it. This time I powered it with my RPW-7 halfrack power supply instead of a regular adaptor.
Man, that thing is now really noiseless!
The Limiter is so great! I made a "Baby, where have you been my whole life" experience with it! I'll keep this underestimated gem, whatever may come!  |
