It's taken from a set of pictogram cards that my wife uses in the classroom. This one meant "Speak with your neighbour", I just had to add the eyes.
My first version DLS looks better, but the Mk3 is a huge step forward soundwise!

My pedal is based on mmolteratx' schematic, with the aforementioned corrections (R3=1k, R9=680R):

i've built this effect, finally!
...what are your impressions about the sound?
i've used 2N5457 on mine and i have a HUGE distortion, a wall of saturation, with massive bass freqs and kind of scooped mids (it depends a lot on how you set the mid pot and the internal trimmer) - the sound with gain at max reaches the border-line of fuzz, good fuzz, slightly big-muffish but with it's own character. I REALLY LIKE IT!!! despite having a LOT of bass freqs i find the sound quite defined and clear. better with single coils than humbuckers IMO.

also i have noticed that the internal trimmer is VERY effective: it acts like a presence ctrl, it could be interesting to use an external pot instead.

I made the semi DLS mk3 you made with transistors 2n5457.To sounds very bass especially when added to gain.Not sure I really need that has a low frequency, as well as for bass too. Guess I'm se.Replace C5 2u2 (2.2 micro farads) with 0.22uf (220n), and got a decent sound.thank you

Hi.I'm making MKIII and I have a question.

I'd like to add Gain2 and Mid2 pot. Can I change Gain1 to Gain2 and Mid1 to Mid2 with one 3pdt foot switch? I want to change Clean (a lot of middle) to Crunch (few middle) in chorus. I edit schematic. Please check this one.

GV.gif


I wonder if GND can share 789 pin. I want to use 3pdt that's why share it. Do you recommend separate this?
(I dont need LEDs for check Gain1/Mid1 or Gain2/Mid2.)

If this schem have other problems, tell me please. thank you.
P.S. I use mmolteratx's schem.thanks a lot.

I am pretty sure you cannot do that without affecting the operation of the circuit.

Please post a copy or link for any schematics you are referring to, I have no idea which schematic your bit fits in.

No that isn't going to work because the parts that are not tied to ground will interact. How will only be ascertained by breadboarding it (but personally I wouldn't waste my time).

yes, deltafred is right, your switching method will not work

there's a way to do it with a 3PDT anyway: just use 2 gain potentiometers with doubled value and connect them as in the image.
the wiper will be slightly different, but you will save the pins for the MID pot switching.
you could make the same for the MID pot and install a LED too - in this case the change of the wiper would be more pronounced because the mid pot is linear ...but give it a try if you want, perhaps it will be ok afterall!

Thank you for information, deltafred.
I'm stupid... :oops: At first I'll make this fx by breadboard and check!

Thank you for reply and writing shem, Intripped.
If I use pot with doubled value, I dont mind about ground, huh? It is great information cuz I can use LED. Im going to try it and confirm it!

you need doubled-value pots because in the circuit that i posted the 2 pots are wired in parallel; and 2 resistor of 2M in parallel = 1 resistor of 1M
yes, i know that those are potentiometers and not resistors, but it works in the same way:
look at the potentiometer on the left in the image - pin2 is disconnected, and so it is exactly a 2M resistor in parallel with the other 2M pot. in this way it's like having a 1M pot - only the excursion of the (used) potentiometer will slightly differ from a 1M log pot

google "tailoring potentiometers", you'll find an interesting PDF

Hi, Intripped.
I'm studying about electric. ur reply helped my understanding and I learned about parallel and series.
I google "tailoring potentiometers" and I'm watching PDF, it's so nice. I'm going to look carefully.
If I can make fx well, I'll report. Thank you, thank you.

P.S. I apologize for my cheap English.

Just finished my build using IVIark's vero (thanks mang!) I have 2N5457s in it and have followed the advice of a few of the guys here and this is what I did:

22n in place of the 100n cap
220n in place of the 2n2
220R resistors going from Q1 Drain to Q2 Source And same for Q3-Q4

Overall I'm pretty pleased. When compared to my original DLS MkIII, it sounds pretty close. I only need to do two things in order to get my build 100% to my liking:

1. Decrease the overall gain - mine has a little too much at the minimum setting
2. Decrease the Bass - the original pedal is pretty bassy, and I think my build is similar, but I'd like it to be a little more useable.

Any tips are greatly appreciated :thumbsup

1. Decrease the limiting resistor on the gain control (47K to ground) to 33K or maybe lower, and it should bleed more signal to ground and give less gain/volume. Or you can take it out completely, it's basically a volume control of the first gain stage being fed to the second. If you turn it all the way down, it's the same as turning the output volume control all the way down- it sends all the signal to ground.

2. Decrease the value of coupling caps, the 220n on the input and output could be halved(100n~120n) and that will kill some bass. It is usually more noticeable on the input.
