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.


If you want the PCB without parts there's a link for that at the bottom of the page.

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.

Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls, in a 1590B. 1590A will not take a battery. Knobs are not included.

Easy and brilliant 5 product stars
"My first build from fuzzdog and couldn't be happier. Worked first time for the circuit board itself and any issues with the switch was my own doing. Good instructions and clear PCB layout making any problems easy to identify. Boost itself is very usable and a good addition to anyone's board. Been properly bitten by the bug now so will be ordering many more soon!!" Joey - 14 June 2020
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 August 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 July 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 November 2014

"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 January 2013
