The diode clipping looks good...the other lug is just unused to bypass the distortion.  Check out the AMZ page, they have tons of info on clipping!!  ;)

Aron,

Thanks for the confirmation on the volume pot and the other info, this makes me feel like I didn't make this incorrectly after all :-) I'll post my progress. What a great learning tool this has become!

Thanks again,
Rob

Well, I have it all completed, and now have my 3 knob booster with an LED. This thing's really sweet. I'm not sure how usable the tone control is at this point, but I may keep playing with that. Thanks again for the great info Aron!

It works! Finally, after 2 attemps and much much trouble shooting, Ive got a circuit that works. I love the way it pushes my Fender Champ into overdrive heaven :) The volume swell is just phenomenal.

Great circuit.

Thanks to Aron and all that have helped answer my annoying noobie questions.

Great! Congratulations! Can you tell us what problems you encountered?

Well the problems I encountered were all my own fault.

Basically I used the wrong resistors in some places.

I felt proud of my DPDT no LED hookup diagram though  :D

So this is my first own-built effect, thanks to aron :).
I had some difficulties with it, cause it didn't want to work for me. The problem was that the input, the part itself, was bad, but now it's ok, IT WORKS! :)
The other problem is that I could only get a linear pot, and it really makes a difference. I've scaned all the radio-part shops in Vilnius(the capital of Lithuania, where I live..), and they didn't have any non-linear pots. It really sucks, still don't know what to do..  ???

As far as I am not going to use it for a guitar, I haven't made a box for it, it looks like this:


The soldering is terrible but, you know, I just need more practice.. :icon_rolleyes:

Thanks again aron, for a really nice and usefull website!  :icon_idea:

Good job. Just snip off the unused leads with a wire snipper.

Nice to see the work of others.

Yessir, I did.

I built this booster last night. I was looking for a clean boost to use after a TS Clone I'm building. I tried the LBP2 and my build was more like a very mild overdrive. Additionally, it did not seem to have added much in terms of volume. It sounded fine but it was not what I was looking for. The NPN Booster fits my needs better: cleaner and louder. It seems to add some treble though, giving the strings a bit stiffer 'feel'. Would adding a tone control, to bleed off some treble, help 'soften' things up a bit? I am also considering the addition of a volume level control. I drew up an NPN Booster schematic based on the G. Smalley original and included the tone and level circuits where I think they would go (in red, see below). Would this be correct?



Also, I added a pulldown resistor as a precautionary measure.

it has a mid boost and top end roll off with a small amount of parts

Thanks Gus. It looks interesting. I'm trying to learn so I hope you would not mind some questions. Would R5/C3 be the mid boost, and the R7/C5 the treble roll-off? Referring to my diagram, would the tone and volume control ideas work?

I just built this again for the second time only this time I added a mod (with help from others on the forum) that allows me to switch the input cap.  Now I can switch between treble and full boost.  Bitchin!  Thanks again Aron and Gus.

Well, I just finished this the other day. I used this stripboard layout though, as it's much more compact (and easier to use :p). I must say, this little thing can get pretty damn loud.

Here's a few pics. Keep in mind my camera sucks at close-up shots.

here is my build outside the box:


I am using the booster after an option loaded TS, but instead of having two separate boxes, I have both housed in the same box.

Okay, so I just build this again (third time) but for a friend this time.  Hey, it's a great little circuit why not go with a good thing?  Figured I'd include a picture this time.  The toggle just switches between input caps so you can have treble boost or full boost.  Thanks again to Gus for a cool circuit.

Is this mod easy to do?
Might aswell try it since i haven't got down to building this project yet

Built the npn boost a few weeks ago and I have caught the disease (despite the numerous warnings).
Building both a bazz fuzz, a dist+ and even making my own housings from scrap sheet metal.

I started building this pedal today. I got it working, but without any switch. It sounded pretty good. That's where I started having problems. I tried to wire it up to a mono input jack, as in Brian Wamplers book on building effects pedals - beginners. It didn't work. So, I tried it to a stereo jack as in your picture, but the same results. My brain is fried. I can't think any more so I'm gonna put it away and jam for a while. I know the switch works, cause I pulled it off a pedal, not in a case that was working.

I figured it out - the battery was too low voltage (6.67V) and the LED was burnt. This thing adds a lot of volume. Next is to put in in a case and add the 9VDC jack. Thanks for a great project Aron!!
