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.

molto bello. bravo, bel suono vintage
ReplyDeleteYou can tag this as Verified. It works properly =)
ReplyDeleteExcellent, nice one Bo
DeleteI just finished making this and it sounds great but when I have the pot fully anti-clockwise I get a hissing noise. Is it a grounding issue?
ReplyDeleteSo i made this last night and it works nice but mine is not at unity it is very boosted. Iv used tl082 instead of the correct ic do you thinks this is why it is boosted. And can i just lower the 12k to say 4,7 or 6.8 or so will this push it down you think
ReplyDeleteIs it ok to sub the ic with a 4558? I have some tl072's coming in the mail but I'm exited to test this baby out
ReplyDeleteI completed this circuit a while back (so I thought), but still haven't gotten it to work properly. I'm using it in an "always-on" scenario and, once I get it working, it will be installed inside the Bandmaster based amp I just finished building. I am getting very loud white noise when I plug it in, and you can just barely hear the guitar through it, and it sounds very broken up. The white noise is almost too loud to tell whether or not there is reverb, but I'm pretty sure I hear some when I strum the guitar. I've replaced the BTDR (I used the short model), as well as the 5v regulator, and I've swapped the TLO72... I'm getting a reading of 4 volts coming from pin 3 of the BTDR, which seems odd. The issue seems to be somewhere around the IC. If I use an audio probe on the chip, I get dry signal at pin 1, the white noise from pin 7, and nothing from any other pin.
ReplyDeleteCompletely redid the board, which fixed the problem, but the effect brings down the voltage coming off of my power supply. I built a little 9v reg daughter board, and I'm still getting 8.7 volts when I plug in the effect, but I get 9.3 when it's not plugged in... Should I use a supply with a higher amp rating?
DeleteSuspect this will fit in a 1590A? or no?
ReplyDeleteDefinitely not. You might squeeze the PCB in but you still have the reverb brick which is bigger than the tagboard.
DeleteLight modualations with the short decay brick too.
ReplyDeleteBut it works properly and has a beautiful sound.
Nice straightforward build. Sounds decent. I think I'm gonna leave it stock. It had a huge boost though. Like using an overdrive pedal for lead boosting. I swapped the 12K resistor for a 3,3K and that did the job. Anything larger than that resulted in a volume boost.

DeleteArgh, sorry about this. I had a mistake in my first build. Did two more and the 12k is just about right. I though this was a little bit too dark for my tastes so I made just a bit springier by cutting the low end of the tail. This can be achieved by subbing the 1u cap at the lower left corner with a smaller one. It doesn't need to be polarized, it's only electrolytic because in 1u value they are cheaper than other kinds, I guess. I put a 10n there, did the trick. Anything smaller than that I found a bit overkill.

DeleteIm sure this is OK, but just to check - is it OK to use a 5.1K resistor instead of the 5K?

ReplyDeleteThis seems like a dumb question but ... the "Mix 2" and "Mix 3" go to a potentiometer, right? Is there a specific one to use? For the off-board stuff, can anyone recommend some parts? This is my first build of an effects pedal and I think I'm lost in the tiny details. I would really appreciate it.
ReplyDeleteHey check out the offboard wiring link here http://tagboardeffects.blogspot.com.au/2012/02/offboard-wiring.html
DeleteI did a lot more reading and found out that what I didn't understand was "What is a stomp and which one do I need to buy for this build?" and it seems they're pretty standard and there isn't a lot to know there. None of the diagrams here or in the wiring diagram seem to label to stomp switch. The comments in the wiring diagram section eventually answered the rest of what I was wondering about, like what "D1" was in the wiring diagram.
DeleteAnd I almost forgot... thanks for answering my question. I did start in the Offboard area, but I had to really be looking for specific answers in the comments of that page to see what was missing. Thanks again.
Deletehi there man and welcome!
Deletesince this is your first build, i feel like i have to ask this.
do you have the BTDR-H2 reverb brick? cause that's what will do the reverb job, and you can't see it ether in the picture. you only see it's connections.
it's this little thing

Hahaha, yes, I have the reverb brick, and thank you for checking that. I am only still missing the LED since I didn't see it at first in the schematic, and I still have to double check that I have all of the potentiometers I will need, including the one for gain that I'm planning to replace the 12k resistor with. I also need to find a project box that will fit this. This site is pretty great. I wonder if anyone ever did make a wiki to collect these great designs.
ReplyDeleteHi, guess I'll need some help here. I only get the reverb signal at the output. I'm losing the dry signal across the 22k resistor. The resistor is fine, there seem to be no solder bridges but no signal at pin 6. Voltages are fine. I might throw the board out and a new one in, but there's no learning effect that way.
ReplyDeleteThank you so much for this blog, btw, very much appreciated.
Btw, my name is Markus, no idea why my ID (Mesquite) isn't shown...

ReplyDeleteFound the time to go over this build again. Never trust your supplier! What he labeled as 12k were actually 470R. That's where the signal went... Put in a 10k and...great pedal. Love it. But - I learned a lot about the circuit and a valuable lesson: check every part you're using. Should have seen it though; yellow and violet on a 12k doesn't make much sense.
ReplyDeleteI've built 8 of these and they all sound amazeballs. I used a 15k in place of the 12k.
ReplyDeleteBuilt this, worked first go, I like this more than the Equinox II, which is more a spring reverb style. This is quite nice for a 1 knob reverb.
ReplyDeleteUsed the long brick, and 4.7k instead of the 5k.
so i put it all together but instead of any reverb im getting a reaallly messed up gated fuzz sound, i dont know where i went wrong any advice?
ReplyDeleteHi everybody, one question... The mix 1 goes to ground... Any point of ground is fine? I have conected to the ground of the DC Jack, that should work?
ReplyDeleteThanks!
built and sounds magic!!!
ReplyDeletethanks to Ivkark for this layout!
used Short BTDR, the rest as layout...
Here's mine...
