im gonna get killed for this one...a simple question for you all

[missing_dave]

i did a search for a half hour on here..just had a simple tube screamer mod question..where on this link (picture) is the .047 cap ? i wanted to increase the bass.i found the info "schematically" speaking...but im still learning those ropes     thanks..i love it hear wish i had more to contribute..some day. thanks everyone!

heres the link:

It's one of those yellow caps I believe.
It will say 473 on it.

Im guessing you mean uF (microfarad) so look for a cap that says 473 that is the code for .047 uF.  There may be more than one but at least that will narrow it down then you just have  to follow the traces until you find the right one.

Aron's got a page around here somewhere that shows all the different ways values are marked on caps and how to read them. It's probably somewhere in one of the FAQs or something. It's pretty useful for when you are trying to ID a cap.

thanks guys,and john... i will also look up arons ID info..no luck thus far but its here.....also im almost sure its the one below the op amp? the other two(please excuse this) yellow caps  in this circuit ive changed last year and i remember them pertaining to the buffering part of the pedal??
    thanks again!

Here's Aron's FAQ:

I guess this stuff is in the wiki now.

And here's the page (linked in the FAQ) on how to read capacitor values:

And just so we're clear, just about ANY question is fair game here.  The working assumption is that there will ALWAYS be guys like yourself just starting out, and that those very same guys eventually turn into more knowledgeable guys, because folks who are already somewhat more knowledgeable will answer those questions.

It's a learning place, and as long as the question reflects a desire to learn, I can't see how anyone would knock you for it.  And if they did, they'd have me to answer to.  So don't be afraid to ask; we've got your back, dude.

Now, if it is the kind of thing that has been asked about so many times that it is pointless for someone to spend time tapping out a reply when there are umpteen likely better replies already in the archive, don't be surprised if folks redirect you there.  Just keep in mind that if there ARE umpteen threads and replies in the archive that's a sign that it is probably a very good question to ask, because obviously it has interested plenty of folks before you.  Millions of people every year ask how to use a clutch, and millions of times they get told.  Still a pretty good question to ask...if you ask me.

thank you mark...i am an avid diy and gear page socialite and really appreciate your post..i read as much as i can and have been finding it hard to put some of this stuff together..alot of it here goes over my head but i just keep reading...just some stuff i cant put togther on my own..(or just have a hard time finding it )im using the TS9 as my home base and starting point (as its the most common and widely modded talked about pedal)

maybe you could shed some light on one more thing..or anyone..

has anyone ever seen a picture of tube screamer guts with the values next to the parts??

i can find diy versions and parts lists...but some of the parts in the TS9 are not easily identifiable (even with arons guide) i then figure i could match them with the real schematic and that will put the pieces together?(thus teaching me how to read schematics better with a pedal i kinda get)
i do know alot of it is the buffer as ive seen pics of it with it removed( also the  diy parts list for a TS is small) not alot going on...even a fuzz face would be a good place to start as those seem even easier?  thanks again

to bad i couldnt change this thread title to "a beginners look at schematics vs gut shots, learning the ropes"

The first part of your post nearly guaranteed that you would get help! :-)

[Mark Hammer]

And just so we're clear on the cap, your instincts are likely correct.  I don't know that layout at all, but I know the circuit well enough, and from the looks of it, given that the 51pf cap (the green ceramic one) and the clipping diodes are on the "south side" of the 4558, the chances are pretty damn good that the .047uf cap in question will be one of the two yellow ones indicated by others.

And of course, keep in mind that those yellow caps tend to use the value code where the the first two digits are the most significant digits and the last digit indicates the umber of trailing zeroes.  So, 473 = 47000pf = .047uf, and 510 = 51pf (no zeroes after 51).
