Want to do a Treble Boost or SHO

I have a set of baby monitors that are a few years old, and there are some transisters in there labled 3904 313, and 3906 313... will these work for a SHO? I had hoped to repurpose other electronic devices for my SHO, but there is almost no lead left on any of the components. Cost is a factor for me, and the demos I have seen of the SHO are exactly what I am looking for to boost my Vox AC4TV8. This is my first build of a pedal, and have scoured the forums, read nearly all of 11 Gauge's threads on this... but there is so much discussion of making mods to the circuit that I get lost. I have the layout for the SHO, but wondered if its possible to build this point to point wired, without a board to put it on. What'ya think?

Transistors are so cheap, you may as well just buy them. For me, the only real cost of a pedal is the enclosure, jacks, and controls. The electronics are dirt cheap.

OK, well, I guess I will go to Radio Shack with my list. I have a couple jacks, can come upwith a cool enclosure on my own, but I will need the pot. Thanks!

Radio Shack is so expensive it might be cheaper to order your parts, even with the cost of shipping. Also, they sell the worst quality stuff, IMHO.

They will not work for an SHO circuit, however you can use the 2N3904 for a LPB-1 booster clone which is as simple to build as the SHO.
Radio Shack sucks for parts. You will get better quality parts for less by ordering away for them.
Small Bear Electronics has all the pedal parts you will ever need.

Buy new components, they're cheap. However, re-purpose the baby monitor enclosure to house your booster. THAT will save you a few bucks, and look cool sitting on top of your amp.

I've only been building active circuits for the past year or so.. and I built the .011 Gauge version of the SHO without issue last weekend.. point-to-point. It's an easy and useful build. I used small trim pots for the Bias and Master Volume.

..oh, since the thread title mentions a treble booster.. Search for "orman muffmaster".. that's Jack Orman's Rangemaster circuit.. instead of PNP Germanium, it uses a NPN Silicon transistor.. The 2N3904 would be super for that circuit. ;)

This is perfect, thanks!

Ok, this might Ned a new thread, not sure.
here's what I have now, what can I make?
10 megohm resistors
100k ohm resistors
4.7 k ohm resistors
A perfboard
Battery clip
IN4001 diodes (2 each)
47uf electrolytic capacitor (1 each)
10uf electrolytic capacitor (1 each)
NPN transistors: 5 each of 2N2222, 2N3904, 2N4401
I want to make the SHO Slambox but i am missing at least the 100 n capacitor and the 9.1 v Zenger diode.

Is there any way to cobble together a boost from these components?

I think the "Zenger" diode will be so hard to find that you have to scrap the project.I feel very sorry for you!

Ok, I got some zener diodes (12 volt in4742a, 5.1 volt in4733a) Abdul the requisite resistors for the who... will these diodes and transistors work with this?
transistors I have are listed above. Sorry to sound so ignorant... but I am ignorant. I have a perfboard, with no copper traces... can I use this?
At thispoint, I am feeling that I have bit off more than.I can chew,but want to finish it, and need to start somewhere.

First,donīt apologize for not knowing everything.Only a 3 year old child or a fool "know" that they know everything.Secondly,I apologize for the "Zenger" joke.I just thought it was a funny name.It wasnīt a "I know everything and you don`t"joke.I think that the Orman Muffmaster is a good place to start too and you can use the perfboard instead of a PCB.I would advise you to buy the resistors,capacitors and transistor.The things that are expensive are the box and the stompswitch.P.S.I think that you should do some reading on what zener diodes are and how to use them.

Great, thanks very much for your input! I love what you can learn at the TDPRI, by just asking!

Here is a page with some information on zener diodes.
