    I’m using an old Crate glx half stack and using a Boss ME-50 pedal.How should I place the LPB-1 in the loop.I was running through my Boss,then the LPB-1,then to my amp.When i’m trying to come over everybody else on solos,my sound goes to crap.I don’t have the dial even past 10 o;clock.The Boss ME-50 effects on the pedal are set to the MT-2 distortion.Main out put is at 12 o’clock,with distortion output at about 10-11 o’clock.Any help would be greatly appreciated.Thanks,Russ

    Could you try to describe what’s wrong with the sound when you boost? It’ll be easier to pinpoint the problem if we know what it’s doing to the sound.

    It seems to decay(loose boost instead of gaining).I’ve tried several different settings.

    Hm… Kind of strange. Placing the LPB-1 last would usually give you a pure volume boost.
    What kind of outputs does the Boss unit have ? (Like DI out, Amp out etc. ?)

    It has a left(mono)and right output.Line/headphones out

    I’ve noticed, when using the LPB-1 with my Fende Pro Jr. that, if I play at a considerable amp level (let’s 5-6), I get an ‘anti-boost’ (i.e. lower volume) when I turn the LPB-1 below 10 o’clock. With the amp below 5-6, I get a great boost, with no extra overdrive, when I put the LPB-1 at 12 o’clock.

    IMO First of all you should put the LPB-1 first in your chain to boost the pure signal (signal conditioners almost always go first in the chain). Also the decay effect or loss is just the pedal over saturating an already boosted signal due to your other pedal I think. This is a common thing with some EHX effects. Also if you are at high volume having the LPB below 9 can weaken the signal, almost a quieting effect as the other guy described. I usually always keep my LPB at 10-11 and never go above 12. Also check your battery if you aren’t plugging it in :)

    This is usually a good idea. But in this case I don’t think putting the booster up front will do anything but raising the volume. That Boss board is a buffered, digital COSM unit, whereas the LPB-1 is a simple one transistor gainstage. Can’t boost a byte into overdrive now can you ??

    Lol true but I use it behind my modded Tubescreamer and it really enhances the effect or any other one in my chain for that matter. He is using solid state anyway so there is no way to boost it into overdrive right? Why would you use it after a distortion? What is the different effect created? Sorry if this is getting the thread off topic.

    Seems like the problem is that the unity gain factor changes according to which effects are used.

    Here’s a thought: Why don’t you put the booster in front of the Boss unit, and use it as a high/low volume switch. You keep the volume down on the LPB-1 for rhythm work, and then when you disengage it your signal goes undisturbed into the Boss unit and amp at a much higher preset volume. Kind of backwards way of doing it, but it should work just as well.

    I’ll have a go at answering this. (and don’t worry about the thread wandering slightly) I use my LPB-1 quite a bit in different situations and distortions running into it can sound really good….it seems to add a really nice tonal quality imo, but it generally sits somewhere in the middle of my chain. my favorite ‘clean’ tone is the soul preacher into the lpb-1 it sounds bloody great, I don’t know why but it does! and I also run it between 2 dirt pedals sometimes, that way I can use it to drive the pedal after it into higher gain and also use the drive before to push the LPB-1 which seems to enhance the top end and make it sound really jangly. I seriously wish I owned 3 LPB-1’s I could use them all over my set up!!

    Personally I find the LPB-1 circuit to be a great little building block for other effects. I have made quite a few of these myself. Combining two LPB’s in one box is very cool. It creates a nice and dynamic crunch/overdrive. My current favorite LPB is one where I’ve combined it with a slightly modified Big Muff tone control and have a switch which changes the frequency response to go from linear to treble boost. A real problem fixer wherever it’s placed! I also love the jangly character it adds. And as stated above: adding a compressor is really nice. Soulpreacher, LPB-1 and a Deluxe Memory Man into a small class a tube amp = bliss.

    Hijacking already: I love mine with just a couple back-to-back 1N4148s/914s to ground at the output. Makes any amp instantly crunchy. Yummy… :)

    I guess those diodes makes it a little bit compressed too ? Nice idea. I’ll try that tonight.

    The idea of turning any booster into an OD with diodes to ground at the output was actually from some DIY website I don’t recall. It does sound a bit compressed, yeah, but not so much. I usually prefer germanium diodes, but from all I’ve tested (1N4148, 1N914, 1N400X, 1N60, 1N34A, 1N270, LEDs, etc.) I liked the silicon ones best. Not a real difference between 1N4148s and 1N914s to my ears. A small trimpot in series also wouldn’t harm and could help getting rid of some of the compression.
