Solid info there... and a little Googling can source other similar sources.<br /><br />http://www.generalguitargadgets.com/how-to-build-it/technical-help/beginner-information/<br /><br />http://www.generalguitargadgets.com/how-to-build-it/technical-help/<br /><br />http://www.geofex.com/Article_Folders/howto.pdf<br /><br />That PDF there covers your questions and more. But, in short:<br /><br />Most pedal circuits don't need more than 1/4w resistors. I've not run into one yet that needs higher wattage. Amps are a different story.<br /><br />You can pretty much use whatever kind of cap you have handy (except where you need electrolytics). However, ceramic caps tend to be noisy in the signal path. I usually limit ceramic to power sections and use film for most everything. However, sometimes those little MCC ceramics are the only thing I have in the small values... so I use them. No big whoop.<br /><br />I hope that helps you out in sourcing some good help info. I'll look for some more links as well.<br /><br />Good luck!Wadhttps://www.blogger.com/profile/14251752851523934130noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-55566491898594574732021-09-26T11:31:11.874-04:002021-09-26T11:31:11.874-04:00Hello :) I have a couple more questions about buil...Hello :) I have a couple more questions about building pedals in general.<br />How do i know if i need to use 0.25W or let's say 2.00W resistors for example?<br />Also, does it matter if i use metal or carbon film resistors?<br />Same question for capacitors, does it matter if i use film or ceramic ones?Anonymoushttps://www.blogger.com/profile/07626072324636384036noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-7487019687440975682021-09-22T15:16:25.432-04:002021-09-22T15:16:25.432-04:00Correct, everything but pots goes on the component...Correct, everything but pots goes on the component (top, non-copper) side.

The pots would be backward as well and you'd have to put them on the component side. At this point you'd be having a hard time getting them to fit on top of resistors and caps unless you're using long leg pc mount pots or wiring them off board. Probably easier to just etch a new board that's not mirrored.

The Light Land schematic has these (D6-7) going to Vr instead of to ground as in the layout. When I pull D6-7, it fires up pretty much like a juiced Lightspeed. Sockets FTW.
