I don't see anything connected to the input cap. The guitar signal has to reach the input cap to have sound.

if your talking about the wires from the jacks i left them off to make it easier to see. i can put them on and take another pic.

I don't see it either. From what I can see it looks correct but I get a headache when trying to follow a breadboard. What kind of transistor? Check the orientation of the transistor and caps.

i checked the transistor and the caps theyre facing the way theyre supposed to be facing heres the pic with jacks



the transistor is a 2n3904

I can't figure it out. Anyone else want to try? Measure voltages at the pins of the transistor.

providing each arrow points to the right component, aren't you missing the connection +22uF,10k,100k,47k.

also where is your output wire, is the white on top right? then it's connected to ground

so would i hook the white output wire to the - side of 10uf?

ran 100k from +bus to 22uf, orange jumper, 47uf

so i need E---22uf--------100k-------- + bus
                      I
                      I
                    47uf

 i dont know how to connect the 22uf and the 100k to the circuit

sorry m8 I'm in a hurry now, but try this : move the white wire and the blue jump at the end of the black lines I've drawn, that shoud fix it.

so im hooking the blue jumper to the 10k resistor and then moving the 47uf cap right?

thanks for your help. i got noise but i have to pick hard and have my guitar and the pedal turned all the way up.

Sorry for confusing you Chris!

leave the blue jumper there, and add a wire from F15 to c10, that should make the connection +22uF,10k,100k,47k

thanks armond. i got it to work. except theres no distortion. i like the added boost and if i turn on the gain and reverb on my amp it sounds cool.

there's no distortion ? that's great it's not supposed to distort ;D , just to boost your signal.


just one pot, the one called Boost 5K
