im leaving in two hrs. to go to some electronic stores for unrelated business and was wondering if any body has a simple pedal i can make. i just feel like making one today.... (girlfriends out of town) :'(

Make a FuzzFace - simple, cool, Ge or Si - both are great.

do you have the schematic and about how much will it cost? i allready have board and enclosure.

  What other equipment might be augmented by such a build in your case ?
  Look at 'loop pedal', study 'buffer', check out 'impedance ratio' and 'impedance matching'.
  Choose a topic such as 'Fuzz Face Schematic' and type that in google.
  Some of the other stuff is harder to find, see GEO, try to form questions.
  As much as I like to say Tube Screamer, I'm aware of the back and forth over it's strengths and faults, and the phrase "whatgozinta-comesouta" [which works good when typed], may have something to do with praises and alleged shortcomings of the typical TS type circuit.
  I have one of this type on my board, the third control helps it adapt, and the midhump business either irks or illicits fond comments.
  Although I never used one, a breadboard.
  Which isn't bad in/of itself, not that I can recommend building tweekable boards, either ways it's back and forth to find 'it', so is seems. Sometimes 'it' is shown exactly on a schematic, and all the 'tweek-arounds' aren't a waste of time only for the fact that your'e always learning something like the basic Stratoblaster circuit was just fine in this case.
  Also, "it" changes. It is your amp, your guitar, any other pedals, and the speaker, everything from the source to the transducer is 'it', any change such as volume or impedance could illicit change in everything else.
  Omega combines impedance and volume boosting, nice things to have in a box.
Convention creates following, following creates convention.

finally, another bass player on here!!!  :)  I'll second the bazz fuss, it works decent for bass, is simple, and easy to modify.  Make two in series and you've got the Buzz Box.  Darlington config of transistors helps gain and bass response imo.

they should make a bass only section on the boards. most guitar stuff doesnt work well on bass.

ok i found this and im thinkin' of making it but i need some basic help. i will post the picture of the schematic in 5 mins. the circled stuff is what i dont know what it is.

ok questions

1. what are the triangles? are they pots? what are the numbers mean.
2. what are the
  ----
   --
    -   
3. on the bottom next to the 680k resistor what is that (10 uf)
4. why does it say audio next to the 100k
5. what is the
-------l l------
        .1uf
6. what is D1 and D2? SI or GE what will work better for bass?
7.can you explane the input and out wiring?
8. why two swicthes? cant you just use a DPDT swicth??
9. why is their only one wire going to the out?
10.what does the 4558 in the triangles mean?
11. Can you tolerate my noob status?

This should be fun  :o

#1:  That is how an IC is shown on a schematic.  The numbers are the pins. 

#2:  That is how ground is shown on a schematic.

#3:  That is an electrolytic capacitor.  Note the + and -.

#4:  That is a pot.  Audio is the taper of the pot.

#5:  That is a non-polar capacitor.

#6:  Try some and see what YOU like.  Everyone is different.

#7:  Tip of input jack to circuit,  Sleeve of jack to ground.  Same for the output.

#8:  Only one switch.  That is how a DPDT switch is shown on a schematic.

#9:  The other wire will go to ground.

#10:  That is the type of IC that you'll need.

#11:  Everybody's been there.  Your're just a little more up front about it.

If any of that is wrong someone smarter than me will correct it. :)

Having said all of that, you should really check out the beginner project.  I think a little more use of the search function and some time at the Wiki will help out a lot.  You don't want your project to be a flop, so do little homework before you start.  Have fun and good luck.

thanks that will help alot. this is a project that im making after the beginner project i was just doing some research.
also in the out jack their is just one wire going their. would i connect all of the grounds to the sleeve?

Yeah,  I meant sleeve and typed ring in my first post.

take it slow.  I wanted to jump right in after i built 2 or 3 circuits and i went for it with an Uglyface.  I must have worked on that thing for two months.  Finally got so fed up i bought the completed circuit on the for sale section!  I've since gained the skill to build one but i wasted a lot of time and had a LOT of frustrations because i didn't understand the theory behind the circuit.  Since i didn't understand the theory i didn't know the right way to debug.  It's still sitting on a shelf above my bench 4 years later.

Well here is a layout for you, if you're using stripboard that is.
Ps. I've not verified it, but it should work fine ( famous last words... etc.   ::)  )

:)

thanks what would i do with out you guys. oh and mikey do you still have it on your self? if you decide to throw it away i live in summit next to the cyahoga county line. you could send it to me ;D
also i have alot of PC board from radioshack will that work for this.
this is what it is

so that is one IC unit not two?
also if you have made this how much will it cost about?

It is two OP-amps in one package. The schematic says 4558 but you can swap with TL062, TL072, TL082...
Price? Not a lot... none of the components are exotic.

what are the red dots in the 13 column?
also...
can i use the same battery for the circuit and for the led?
