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
Sorry I have one question: LED+ means that a wire has to go to the positive of the LED only? or do I have to connect that positive also to the DCjack? thanks :)
Hi, I just want to pint out that the lower op-amp was indeed a TL072 instead of an 4558. Did anyone already verify the schematic/layout? Tracing the pedal was a bit hard due to the black solder mask...
Verified! Tried 4558 in both positions and TL072 in bottom position. With both 4558s you get a faint hiss in the background but not with the TL072. Thanks Alex.
HI guys, I cannot find 19k resistors anywhere. So, can I use something else like a 20k or perhaps solder together an 18k and a 1k? Would this still work?
The basspot works when I disconnect lug 1, the treble does´nt work at all, no effect there. When I wire the gain according to the layout the gain is reversed.
Hi,i have a question abaut capacitor C3 and C9 from the schematic. C3 is 51pF,and C9 is 151pF. On the layout C3 is 51,but the C9 is 180pF. is that making any diference ? This is mine first time,so please help.. and wich tipe of capacitors they are ? ceramic maybe ?
If i may note something, there is a small mistake in it though: the wiper of the gain potentiometer shou!d be bridged with leg 3, ie. one cable goes to leg 1 and the other to pot 2 (and three). Everything else is working as expected, so one more verification!
I agree with Panagiotis. If Gain 1 is connected to Gain 2 the pot works backwards. If you instead connect Gain 2 to Gain 3, the pot works as it should.
I built this one today, everything works fine but I have a low output : with level pot full CW, I am only at unity volume. I think it lacks a bit of gain but otherwise the pedal sounds great I really like it. I carefully chechked everything I can't see anuthing wrong. Any idea ? Thanks
Ok, this will be at the top of my list once verified.....
ReplyDeletebuilding it now so i should be able to verify tonight if i get around to wiring it up

ReplyDeleteFrom layout Led+ a wire go to positive led.Negative led leg go to 3pdt footswitch.

ReplyDeleteThanks again, Gavin!
DeleteThanks also to Kenfoe for tracing his original pedal.
Thanks for your props, Alex! Thank you for your nice layout, well done - very compact, I really like it!

Hello, sorry if it´s a dumb question but, what are those transistors?
ReplyDelete2N5089. It says so on the right side of the layout.
Delete+m
great... right in front of me! Thank you! :)
DeleteHI guys,
ReplyDeleteI cannot find 19k resistors anywhere. So, can I use something else like a 20k or perhaps solder together an 18k and a 1k? Would this still work?

Hi Mark, you can always put 2 resistors in parallel e.g. 47k+33k gives 19.38k, or 150k+22k gives 19.18k.
ReplyDelete18k or 20k will work
ReplyDeleteIs the bass and treble wiring correct in the layout, I can´t seem to get it to work..
ReplyDeleteThe basspot works when I disconnect lug 1, the treble does´nt work at all, no effect there. When I wire the gain according to the layout the gain is reversed.
ReplyDeletecan i substitute 2N5088 instead of 2N5089?
ReplyDeleteYes you may, 5089 have more gain.
Deletedo you have the flux-five diagram?

ReplyDeleteGreat layout Alex, really neat!!

That doesn't make any functional difference at all and is not a mistake.
DeleteSecond. The resistance between lugs 1 and 2 is exactly the same wether the lug 3 is tied to lug 2 or not. I tend to omit those as well.
