My 2nd build...and I love it. Fabulous gain and a great bit of grunt. Easy job as well. My first build was an ebay FF kit and I thought that was relatively easy but the Muffer was a breeze. Highly recommended build for a newbie......like me.
I come back here time and time again and it feels that everytime I do I gain a little bit more knowledge.
I've built the circuit and am 99.9% sure that theres no problems with lumps of solder crossing the tracks or anything and that all parts are correct and in the right place but what happens is this. . . .
...In order to get some noise out of my guitar I have to hit the strings quite hard and even then theres a delay between hitting the strings and hearing it.
I've had a look round the interweb and it seems that there is a mis-bias somewhere. I've swapped the transistor but i'm still getting a horrible sound.
I haven't tried to build this buffer yet but it seems like pin 5 does not need to go to the ground. So the jumper from R1 & pin 4 is not needed. All you have to do is put the ground wire in between R1 & pin 4 and make sure that pin 4 & 5 are not connected by drilling out one of the traces. Let me know what you think.
Hi there is this circuit correct? I built it as is but it didn't work, although I can't see how the suggested changes would make any difference as the cut would break the ground connection between pin 4 and 5 and the suggested wire jumper would just add it straight back?
According to the schematics on Kit Rae's site, this will be the Bubble Font because it uses 470pF capacitors. The Tall Font uses 500pF instead which makes it smoother.
Finished my build but cant figure out the problem. All that's heard is ticking (motorboating). The filter and volume seem to be working, but no audio signal coming through. Any ideas will be greatly appreciated.
Sorry but i'm somewhat a newbie with all this and i'm not sure how to do it.
I've got a cheap DMM but am a little unsure what to do with it
Thanx
Dean
Can you post the voltage of each pin of the transistor you used?

Jep, no problem (except for the size) ...
Hi guys. I'm running mine @18volts now, better sound, more dynamics, less distortion. I love it. Try 18volts!
Just a quicky ! It seems i've run out of caps, can I use 100v capacitors ? I know its a little restrictive due to there size but its just to test it.
Thanx
I all,
Can anyone confirm if it is working?

Anyone built a working one of these?
Sorry for wasting time....spotted it. D'oh !
Dean
Many Thanx for that !
So i'm connecting a wire from lug 1 to lug 2. Is that right ?
I am really sorry if i'm coming across like I need to be walked through this but I am really new to this and don't want to get it wrong.
Thanx again
Dean
D, Lug 1 is attached to lug 2 ... I agree, brown on brown is a bit hard to see, let me fix that ;)
On a side note: it doesn't change the workings of the potentiometer, which is wired as variable resistor in this case.
Sorry, lug 1.
D
Sorry again for the ridiculous questions :-) but is lug 3 on R10 not used. What I mean is, is it not used for the ground ?
Thanx

Just a quickie to say a big thanx for this web site.
Just completed the Muffer and it worked first time. I even wired in a stomp switch ('cos I had one laying about.
This was my 2nd build and it was pretty easy to complete, even for a newbie like me.
My next build....the flatline compresser. . . . .
Thanx again
Dean
Many thanx for that. I think i've got it.
Great stuff
Firstly, i'm extremely new to circuit building and stomp boxes so please bear with me if this sounds obvious....
Do I need to put in the LED and the wires ? If so, is it just a normal LED conected across the two tracks with the green wires passing over the cuts ?
Thanx in advance :-)

P.S. Great great site by-the-way :-)

can i ask where is the on and off DPDT switch? heehhe. sorry sir, im a dumbAss..
"Do I wire 1 switch on row 3 and 1 switch on row 4 so it connects over the trace cuts on column 9?"
That's the purpose of the switch: jumper the tracecuts.
I have the same question? Does the switches connect line 3 to line 4 or do they connect the line back to itself?
Can someone tell me how to hook up the Footswitch?
Thank You
I've been trying to find the DIP switch on mouser but without luck.
I'd like to instead add two SPST switches so i can flip between them from the outside of the box.
