Late to the party (there was a party right?) but wishing you a very happy birthday Brian. Hope you had a blast.

Thanks guys. The similarly named vactrols, their reissues and differing layouts of the circuit certainly make it a bit confusing.

What other filters would you recommend Thewintersoldier?

I like the 440 as it's (seemingly) simple and has a low parts count.  And because it's the one Jonny Greenwood used on Paranoid Android.  ;D

Thanks both for the replies. Looking around the different forums it seems that 440 clones (be it the Mirror Ball, Sawse or  EF440 from General Guitar Gadgets) have a very hit and miss success rate.

I've just put my Mirror Ball together using the vtl5c/3 I have and whilst it 'works', there's definitely something not right. The envelope just doesn't respond in the way it should, it's really wobbly and unstable sounding. I'm also getting some background fizzy distortion when using the neck pickup.

I'll give the LED/LDR combo a try as per your message above Jimi but I won't hold my breath for a better result. Fingers crossed though!

Thanks again.

I've been searching for DOD 440 builds on the forum as I'm about to build one myself and came across this old post from Jimilee -

I have the VTL5C4/2 vactrol asked for in the BOM, but can see that in the link above, Jimi successfully rolled his own. I'd like to give this a try just for the hell of it but have a couple of questions I hoped someone might be able to help with.

Here goes - The VTL5C4/2 has 3 legs on one side and 2 on the other - 5 legs in total. If I'm making my own from an LED (2 legs) and an LDR (2 legs) then that leaves an unused pad on the PCB.

Do I just leave a pad empty?
If so, which one?

Any advice would be greatly received. Thanks!

Reading this again, I'm not as clear on it as I thought I was.

Is there any way you'd be able to draw up a basic sketch?

Please and thank you!

Well that sounds sounds simple enough to try.

Nothing ventured, nothing gained and all that!

Cheers, I'll give it a shot and report back

Open Discussion / 2 footswitches, 1 pedal
« on: September 11, 2022, 10:12:36 AM »
Hi all

On my my pedalboard I have a multi effects that I use for a few rarely-used effects that don't warrant spots of their own on the board.

The problem is its noisy when turned off so I'm going to build a bypass loop pedal for it.

Question - Is it possible to build a loop pedal with two footswitches? One latching, one momentay.

Is anyone aware of a project or layout for something like this?

Thanks as always.

Thanks for the suggestions. I'll definitely check them out.

Hi gang

Can anyone recommend a circuit that uses one or more, on-on SPDT switches?

I've picked up some nice rocker switches that I want to put in something but I'm stuck for inspiration. I'm a fuzz man at heart but all recommendations will be greatly received.

I shared some SMD projects on oshpark, including a Sonic Stomp. All these boards are about the size of a US quarter.

Wow, these are amazing. Great work. I'll definitely be ordering some. Thanks.

Hi all

I've got a friend wanting a Sonic Stomp in a small enclosure . Now that the Bloviator has been discontinued  :'( does anyone know of any other boards that are available that will fit in a 1590a?

I recently started reading book 1 from a random suggestion on Reddit. Loving it so far and looking forward to seeing how they ported it to TV. Fingers crossed they've done a good job of it.

I got it from Banzai.

I think I went with the BL08-U version as suggested by Brian elsewhere on the forum.

Thank you so much for the detailed explanation
 Who knew a one knob pedal could be so involved!

Good news: Now that I know how to connect it properly, it works.

Bad news: It adds some crackle to the signal.

When building the pedal I substituted the MPS2222A for a BC547A and the LF353N for a TL072. So my first port of call will be to replace thes subs with the original parts. Fingers crossed that will clear up the crackle.

Bean - thanks for your help. It's late in the UK where I am but will have a look again in the morning. I don't want to use the send/return loop so will try a patch cable between those two sockets. Noted also about the chain positioning. Thank you.

Benny - Yep it's a bit scruffy in places. I'm confident the connections are sound though. I'll flow a bit more solder onto the 3pdt lugs just to be sure. The wire is all stranded though so snappage (is that a word?) shouldn't be an issue hopefully.

Jimilee - I'm absolutely dreadful at following schematics but I think you might be right.
