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
Thank you very much Alex.I been working on a version of this with three 12AX7,mine sounds great but has a horrible low end hum i cant get rid of.I built a charge pump to boost power on pins 1 and 6 to 30vdc,so i think the charge pump is cause the hum but not sure just guessing?
Did you use shielded wire for the ins and outs? Not sure if the charge pump would cause the low end hum but I know if I made one I would for sure use an isolated 12VDC power supply for starters
Some info here and schematic for a real tube-one that shows his 33V DC from an internal DC/DC converter for pins 1 and 6. http://tomsguitarprojects.blogspot.ch/2014/10/RealTube-One.html
I'm wondering if any pump is enough to give out enough current for four tubes. Is it all silent when the converter is out and circuit is fed with 12V instead? +m
I wound up useing my MXR gate after the 2 tubes and now the circuit is perfect.thanks for all the info guys.i still have alot more testing to go with this,once i get all the bugs worked out ill post a schematic since im no good at making vero
Put the clipping diodes before the volume, but after the tone control. What I do is I put two diodes side by side, so that the opposite ends of each diode is touching, then twist the leads, solder them together, and snip off the leads you don't need.
Thanks for this one.. Super excited to get it working! When I first tried it out with a 12V 500mA wall wart I had a terrible hum and hardly passed any signal. I've now upgraded to a 12V 10A power supply (I think originally from a laptop) and it passes signal fine, however there is still a lot of low frequency hum as well as some high frequency oscillation, even when all the trimpots are set fully CCW. The hum goes away (or is at least less noticeable) while I'm playing, however the sound is a bit farty/saggy. Any ideas? Cheers!
Got it! Changed to a 15v 1A power supply and ran into a pair of L7812 regulators; 1 for the heaters and 1 for everything else. I'd call it verified! On a side note, it sounds better to me with 12AU7s in V1-3 and the 12AT7 in V4.
Is there anyway to rearrange this project for a 6N2P as there fairly decent gain and awfully affordable
I’m a novice to tubes to excuse my ignorance but it would definitely be a cool project if worth the effort. I can do a PCB after researching but I can’t make very layouts at all yet though I’m going to try and start learning so I can contribute as well
Ooof!
ReplyDeleteWe Need More Tubes))) Cool pedal! Thanks!

DeleteThat is the converter.
Hopefully this info helps out...

DeleteAnyone have a source for the LT1613 chip? I can only find it on DigiKey and that's SMT only.

ReplyDeleteGood to see the spammers have found us.
ReplyDeleteWhere could clipping diodes be put in. Just found this site I'm going to setup an account in a sec but I got really excited when I found this.

DeleteCool. I think I'll do it with switchable input caps and a switchable diode section.
ReplyDeleteThanks Pat

Good call. I like this idea better than the 33v charge pump. Think I'll give this a try. Thanks to Alex for the layout!
