Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
Nice one. I watched the video it sounds like a great pedal. Very interesting controls as well. I think the video is wrong. It says asymetrical is more compression. Seeing how uually assymetrical is 3 diodes and symetrical is 2 usually assymetrical has more head room. I guess on this pedal it is the other way since its using 4 diodes for symettrical giving it more forward voltage. man i want to build them all ha ha . Great Job Alex
Trying to find a W taper 1meg isnt easy. I really want to make one of these . I love the w taper idea it seems like a great way to do things. I found one with a detent I can wait to try it.
You can modify a linear pot to emulate log, rev log or w. Info including calculator spreadsheet here http://www.pisotones.com/Potes/Potes.htm http://www.pisotones.com/Potes/TaperRes_English.xls It is not a perfect solution and might not work in some situations

I had to custom order the W taper pot, but there are workarounds. One workaround is to use a antilog pot (100K-500K) that reduces the amount of series resistance as you turn CW. This will act like a saturation control, adding distortion & compression as you turn it CW. Then add a switch to change betweeen different diode configurations. While it takes 1 pot & 1 switch to pull off, these parts are easy to source.
Verified! Used BAT85s for the BA282s and will probably experiment with others. Also used A20k for the Hard and a C1M for the soft. They don't work brilliantly but there good enough. Socketed R11 and C10 and preferred the burn setting so adjusted for that. Cheers Alex & VFE.
