    Hey guys,

    I love everything about the LPB-1's tone and how it pushes the sound to the limit especially with my SVT although the only thing I dislike is the low end cut which seems to happen...

    There must be some way for me to mod the component to stop the low end drop off?

    Cheers

    it's supposed to be a fullrange booster, but you could try increasing the values of the input and output caps (like from 100n's to 220n's or 470n's).

    Thanks! Apparently in this case the input and output caps go under the names C-1 and C2? I wonder which value would be best suited, might have to come to a trial and error situation, but hopefully not.

    I do suppose the drop in bass just could be from the general gain boost adding distortion, creating the illusion of low end loss but for my style of music more low end is welcome anyway!

    Have you thought about a Wren and Cuff Phat Phuk B? The price difference is significantly more than a component swap on the EHX, but it's designed for what you are describing. And every W&C pedal I've had has been far superior to any EHX pedal I've owned.

    Doesn't look too bad at all! Have you or has anyone else used one of those phat phuk B's? Was there any low end drop? Funds ATM would be much more willing for me to do a component swap, but ya gotta do what ya gotta do I suppose!

    I haven't, as I don't have a tube amp to get the most out of it (I use a Ginger pedal built by the above johnk for any of my ss boost needs). I have owned a couple of other W&C pedals and can vouch for the quality. There are plenty of players around here that swear by the Phat Phuk B, some even saying it should come with all bass purchases :eek:. The "B" model is a version specifically tuned for bass, so I can only assume that means more low end retention. From what I understand, it also boosts the treble a bit for some bite, which I noticed the LPB-1 does when I had one.
