I'm getting sound and the switches change how it sounds but the envelope isn't working. The LEDs don't change brightness with the guitar attack. Switches and pots will change the brightness but no envelope. I've tried all different switch positions. And played with the pots but no hint of brightness changing with attack. I jumpered the send return pads and connected decay to ground as it said to do in the build doc if not using them

Do the voltages on the lm1458 seem off?

Yes, mine is acting the same way
Where did you two source your LM1458's? The circuit is annoyingly picky when it comes to that IC. (I got mine from Mouser, have a search of the Meatsphere thread on diysb.)

I got them from ebay but I have so e from mouser I'll throw one in and see if it makes a difference.
If I'm honest, my 1.4 Rissole is working, I loaned my 1.0 Rissole to someone and it came back dead (worked originally, now it isn't... urrrgh!)
Tried a new one, it was from mklec not mouser. It's still not working and now the pots don't effect the brightness. I might pull the lm1458 from my working fluffgirl build just to make sure if that's the issue or not.
Did you try it in the dark?
Pasted from Jimiless's thhread:
Worth mentioning that there are a lot of possible knob positions that result in no envelope in a properly working build.
Try the following to see if you're in business:
Top row, left to right (in case my labels/names are different):
Color—maxed; Decay—11:00; Attack—7:00; Sensitivity—1:00
"Moog" Toggle: Right
Intensity (left pot in "middle" row)—maxed; Blend—noon
Switches left to right:
Mode—middle; Range—rightmost position (low); Up/Down—rightmost (up); Bandwidth—leftmost (half)
Hope you get it working—it's a blast!
Wouldn't the dark only effect the sound when the LEDs are working correctly? Right now they are just solid on no matter what, no change to brightness with signal.
I'll break out the audio probe tonight to see for sure but it seems like the signal is not even getting to the envelope detection circuit. Is there supposed to be a jumper somewhere that I might have missed?
Did a little audio probing and the signal is getting to the 1458 at pin two, when it comes out at pin 3 it is louder and broken up like a bad fuzz but I. Thinking this might be normal since it is just the envelope of the signal?
I don't know what I did but it's working now. I think the first 1458 wasn't working and on the second one I had to dial in the right settings. I'll have to get it perfectly dark with some shielding but there was detectable wah sound even without being completely dark!

Now to make an epic enclosure... I think I might bend my own.
I replaced the 1458 and no my LEDs pulse again, but with the mix knob all the way up, nothing

You are not getting any audio? It sounds like your envelope section is working now but audio is getting grounded out somewhere.
I think so too, with the mix turned down I get audio. Could it still be the 1458?

I don't think so, if the led's seem to be behaving correctly the envelope section is working. The 1458 just controls the filter. Do you get audio at the send and return pads?

[/come to think of it, I plugged a patch cable in the send and return and the audio stopped.

I would double check that those jacks are wired correctly, if anything you could just jumper the pads until you get it working. I jumpered them to start off, I like to avoid offboard wiring other than pots until I know a circuit is working properly.

Fantastic, thank you. I couldn't find a data sheet to see what pins did what, so I looked at Alan's to wire it.

With those jacks the pins on the side where the metal raises up and curves are the ones that will be contacting the plug the pins on the other side are switched. If you put a plug in the jack you should be able to see where they make and break contact. I've used those quite a bit just because you can get the CHEAP! on mouser and they seem to be decent quality.

I used the enclosed jacks like Allen used so you can't see any of the pins, otherwise yeah, it would be a heck of a lot easier.

ah ok, they looked similar to the ones I have from the bottom.
On this version what are the order of the 3p4t switches, I'm not quite sure how to label and if I've set the limit for each correctly. Up down is pretty obvious and I think I have range correct...

if you do a search for rissole build log, the original is posted there, also there's a link directly to the build log in the PDF file you posted. I can't figure out how to copy and paste it within tapatalk
Duh... Thanks, did you get yours working?

That was it! I disconnected the effect loop and it fired right up! Du huh, I knew it was something simple and stupid that I did. Now I gotta figure out how those damn jacks are wired internally. I really appreciate your help sir, this thing is killer.
Awesome that both of you guys got it working.
I ordered all the parts for mine but still haven't started.
This thread has really pushed my to get on the ball and get started.

Cool man! Glad you got it going. It's a really unique sound with a bit of a learning curve. I'll be excited to get all the jacks wired up and try the effects loop and expression outs.
Good stuff! A high impedance expression pedal is very useful with some of this Lovetone stuff (I use a high impedance volume pedal, plug the volume pedal Output jack into the effect's Expression jack.)
I expect build reports for these rissoles :)

Definitely a build report coming, might be a bit though, I'm trying something I haven't done before for the enclosure

Can you use a multimeter with a patch cable plugged in to determine which contacts do what?

The enclosure is drilled, should be next week. I'm pretty excited about it too.
