I recently built a treble booster with a dpdt switch that gave me the option of 2 different sounds. What I was thinking of doing was to fit 6 on-off switches that are wired in series and have a different cap on each one. In theory (or in my mind) it should give me 6 individual sounds or a combination. Would this work??
Sorry if this sounds like a novice question but then again, I am a novice lol.
I'm building my first treble booster circuit and I want to know if a .047u cap is the same as a 4.7uf?
Are they two totally different entities or what?
Confused!!

Hey guys. I'm putting together a treble booster as seen here:
But as a beginner (some knowledge left over from school), I'm having a bit of trouble getting parts together. I've been trawling the internet and tutorials etc. but I'm finding it ever so slightly overwhelming :oops:
So the capacitors I need are: 4.7nf, 47nf, 1nf, 47uf, 22nf and 5nf. I've searched on Maplins and such places, but it seems like there are a lot of different types to choose from. There are a few below that I've come...
Is anyone familiar with Mullard C280 tropical fish capacitors that have six bands? Mullard datasheets only show five color bands. I'm looking for a color code chart to identify the following color sequence: brown, black, orange, white, yellow, brown. Normally I would call this .01uf 10% cap, but they are supposedly .1uf, and I'm looking for evidence to support that. I have found a few pics of six band C280's out there, so they do exist. Here's a few:
Hi all,
I'm in the process of building my first stompbox (a crunch style distortion box), and had a question on the voltage values for the electrolytic capacitors.
This effect normally runs 9V, but I thought I might want to try to run it 18V as well for more headroom. Initially I purchased 25V electrolyic capacitors (with 10% tolerance) which I thought would be enough to run at 18V. While some people think this is okay, I see some other people say the capacitor value should be at least double...
Hi all! I've done a few builds, a shin ei, bazz fuzz, electra, and a woolly mammoth.. So I decided to try maybe modding a familiar circuit to suit my tastes a little better... Here is what I have so far... Do I have everything hooked up ok?
Concerning c4, the electrolytic capacitor. I know which leg is the negative one, but I don't know which way round the capacitor should actually be? For instance, the capacitor is being soldered to holes d6 and e6 on the veroboard, but which hole should the negative leg be soldered to and which hole should the positive hole be soldered to?
Another apology for what is probably a very obvious question, but thanks very much for any help you can give me! The...
I am sure this is a stupid question, but.....I just built a madbean muffin top. It was a tight fit, and some of the taller capacitors were slightly touching the enclosure bottom. There was a little bit of hum when the gain was cranked up more than halfway, but I attributed it to the nature of the beast. After 20 minutes or so, it quit working. I haven't taken it apart yet, but am wondering if the bottoms of capacitors will short out if touching the bottom of the enclosure, or should I...
Hi,
I'm looking at a schematic of the Big Muff Pi and I noticed that at the input, there's a electrolytic cap but it has negative toward the input. Wouldn't this effectively block the signal? Am I missing something? How does the signal get through the capacitor that's polarized the other way?
I would like to build the ROG splitter-blend, but I just realized that I had ordered bipolar caps, and the spec shows some polarized caps. I looked at the schematic and then just ordered electrolytic caps for the polarized ones, without realizing that there are both polarized and bipolar electrolytic caps.
Can bipolar be used instead of polarized, for this schematic, or for other schematics in general? I searched and read that you can substitute non-polarized caps for polarized caps, if the...
I have everything EXCEPT the 1uf NP. In this schematic, is it possible to either a) use a polarized one? or b) replace it with a lower value (0.47uF is the closest i have.)
Which capacitor values are used the most in pedals and effects?
I am feeling pretty good and feeling the urge to restock my workbench for some summer projects.
I tend to buy film capacitors in 22, 47, 68, 100 increments. I try to buy in larger quantities to save a little. I don't like to shop for each box I build. I like to have common parts on hand.
Does anyone have a better system?
very curious and hope i can learn from everyone.
Hi, can anyone explain to me why using an output coupling capacitor of 47uF instead of 4,7uf the sound results more open ? (both of them make a RC filter with a 100K resistor, so both let pass everything above the 0Hz). I'm powering the circuit (booster with IC) with 9V. Maybe the output signal is to wide that 4,7 can't manage ? Tx
I'm currently making the guv'nor from the layout below. I'm very new to this and i noticed that neither C7: 10uf or the D1/D2: LED's state which end is positive and negative and was wondering if it isn't mentioned does it matter which way it goes in.
any help would be awesome so i can get this build finished.
I built up a familiar circuit except using non-polarized filtering caps on the power supply and its giving me problems. I cant say for sure whether the caps are the root of the problem, but just wondering in general...is it possible to use non-polarized caps for power filtering?
I have a couple of quick questions I hope someone can throw some light..
First, I'm building a Meathead, one of the caps says is 47pf, but the lower cap I found is 100pf. Would it be much of a difference? I see that the One Knob Fuzz uses 220pf in that position, but also some other values change. Should I try to find a 47pf?
Second, is there any difference when using capacitors of a higher voltage? I have a couple of 200V and 400V capacitors I could use, and I see some builds with big...
The local place I go to for about 90% of my parts.
Its a surplus electronics supply store. ( )
Its like heaven on earth for me.
Its really a surplus store. They don't get their stock from some distributor.
They get all their stuff from things like : People cleaning out their garage. Companies liquidating stock, and such.
Anyway...
Often times they get odd looking parts there.
So here is a cap from my trip there today:
At first glance I thought they were wire-wound resistors until I saw...
I've heard people say that higher voltage electrolytic caps can sound better but in all honesty I've never noticed any real difference. I'd always choose the highest rated cap that can comfortably fit on the board, which will give you some freedom with other (maybe higher voltage) builds and give you less of a concern about spikes. But if I only had a 16V cap for a 9V pedal, I wouldn't be too concerned.
I do like higher voltage ceramics though, better quality and closer tolerances (at least in...
Here is a chart I drew for tropical fish caps, because I couldn't find one anywhere. Feel free to use it however you like, just don't modify it, please... hope it helps.
I decided to put up a post on this because a search of the inter-web didn't really bring notable results...
On my first pedal build, I stumbled on a lucky/happy accident. I was building an NPN Fuzz Face and wired the 2.2uf cap as a variable capacitor and voila! It worked great as a Bass control (50k Lin pot). I wired it with the capacitor ( - side of the cap from the input) tied to Lug 2, and the hole where the + side of the cap would've gone wired to lug 3.
