# SMD capacitors for a guitar distortion pedal

I'm trying to build a guitar distortion pedal.

Alright, a bit about the motivation behind this project : It's my friend's birthday in a couple of days and I wanted to get him a distortion pedal cause he's been saying he'd like one for some time. I soon realized that would cost me an arm. So I figured id build one.

I've been getting into electronics for a while now so i've gathered quite some components but not that many big through hole capacitors, in fact I almost only have smd capacitors and I was wondering...Could I use SMD capacitors to do my biding in this project? I've never quite understood the reasons why you'de choose one type or physical size of capacitor over another when they are both rated the same capacitance and voltage ratings...I hope you can enlighten me!

Heres the schematic and a link to the instructables' project page.

N.B. I have all I need to etch my board and given the time constraint that's another good reason i'd want to use smd as I can just reflow my board...

Just to make sure, because I do realize there are different types of SMD caps. I mean ceramic ones. These kinds :

• As long as they're the same value and type, using SMD should not be an issue at all. – RJR Apr 30 '14 at 5:25
• You do realize that making a pedal work in two days is not that easy, do you? Just saying you might want to prepare a "minor gift" for your friend. good luck! – Vladimir Cravero Apr 30 '14 at 5:42
• 5 days. lol and we do have a back up! haha. – Ethienne Apr 30 '14 at 5:53
• Apart from the obvious things like capacitance, voltage and possible polarity, there's also temperature coefficients, component value accuracy, ESR and so on. Wikipedia. – Lundin Apr 30 '14 at 7:03
