LPB Boost / Treble Boost / Shouting Bird

Everyone needs a little boost now and again, and this dinky circuit is just the job.

At the stomp of a switch you can add a little clean boost, add a lot of boost to crank your output into crazy overdrive (great with a Fuzz Face!), or even cut some signal for those quiet moments.

With a couple of component changes you can turn it into a Treble Boost for cutting through the mix for solos, or even the famous Shouting Bird Treble Boost which will make cats cover their ears at 100 paces.

Board-mounted pot for minimal wiring and easy mounting in the enclosure.

Kit is available with a standard sized 1590B enclosure with battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

LPB is Necessary. 5 product stars
"Everyone needs one of these, its so simple but can make a good amp sound even better. It doesnt seem to add colour to the tone, just a nice boost across the full frequency range." MrG - 30/08/2018
LPB Goodness 5 product stars
"As always with the kits in this page, quality components, clear instructions and great kits. I bought this one to replace my old LPB-2 which was occupying a lot of space in my pedalboard. Now I have the same sound I used to in a very little confined space, I couldn't be happier. Although the LPB is not the favorite go-to choice for most people when they're looking for a boost as it's not "clean" and adds grit and colour, it's a pedal I always use to crank either my amp or the rest of the dirt chain using it as a gain stage, couldn't be happier with my new small little boost. I will probably try to squeeze some new smaller jacks in the enclosure to see if I can fit a DPDT switch to select between the LPB and the Shouting Bird :)" NiLace - 31/07/2017
Great little boost pedal 5 product stars
"Bought this as my first pedal build and it worked out great. I had no experience of soldering or electronics but this is a great introduction to techniques required. Kit contains everything needed and is straightforward once you do a little reading on components etc. I am pleasantly surprised at the sound quality from this pedal and I'm ordering my next kit very soon. Very quick postage too, A+" K Ryan - 21/11/2014
Easy and fun 5 product stars
"I'm only a kid and I wanted to save some money on buying pedals so I found this site, I then bought this kit and I have never soldered before and it worked first time ! The site also provided me with great help and I'm now buying my second kit. Thanks" Conor Anderson - 27/01/2013
