Meaty Balls (My Meat Sack)

The changing of the chip for me allowed the envelope to trigger. Part of my problem at the time was my effect signal was cut off at the expression pedal input because I wired it wrong. So using an audio probe helped because while I still had sound when it was engaged it was dry sound with no wet. I would definitely start following the audio path through with a probe. I jumped all my loop and expression pads initially to sort it out. Kevin at Aion in his build doc talks about how even he had issues with triggering and changed around ics.

When you say you jumped the loop and expression pads you mean using jumper cables to connect the send and return? The reason i ask is I built a tight metal and once boxed up wouldnt work out yes in no until I don't know why maybe read it but used jumpers for the 2 fxloops the pedal has and then the pedal worked I finally pulled it out and jumpered it on the board getting rid of the loops Fantastic pedal by the way I've since built 4 and they all mild deviations in over all tone each one brings it I personally can't say enough as I go on about it............

sorry I know that's alot for a simple question

oh and I pulled out the lm1458 and tried with lm358. I think the lm1458 I was able to get more 'effect' from the pedal but I'm unable to get the extreme sounds that I've heard on youtube. I wonder if maybe my GL5531?'s I bought like 300 of like 8 values of the GL55 series and I don't know a whole lot about there characteristics and varibles except they go on with light off in dark or vice versa shows my knowledge right there
So I can get some meatball sound with both chips one I favor but even with that chip in I'm unable to get anything more when I mess with the rotary switches and I have now read the manual thanx btw think swapping my LDR's out ? Even if the LDR's are from the same batch? or would it be a waste of time and should look else where to get more 'effect'?

I'm speaking about my DEFX board now I'm about to finish up my Aion build very soon so hopefully Ill have something to compare it to haa ha ha h aha ha ha aha ha ha ha aaaahhhhhhhhh......sigh

I guess it cannot hurt to try to change out the ldr but I don’t know if that will really change anything assuming their the correct ones for the build. As for jumping I added a blob of solder across the pads Kevin mentions this in his write up. Here’s the inside of mine for reference.

test with; bandwidth full, Sensitivity max, attack min, decay up higher than attack, like 1/4, color half to full, intensity full, mix more than half.

cool thank you very much

Well I think I have my Meatball working but not getting a very strong wet signal at all . The LED that glows as you play seems to work and turning the pots and switches affects that LED as well so everything 'seems' to working properly just don't know why I'm not getting as much wet signal as I hear on youtube. Anybody have some idea where I could start checking and if use the audioprobe what should I be listening for since I have audio at the output.
Thanks in advance
Also I made my own vactrol using GL5537 is there a difference between GL5537-1 and GL5537 or are they the same?
2 other observations
1 - the only real effect I'm getting is a little auto-wah mixed with a little vibrato I guess is the best way to describe the sound
2 - when using the blend pot at fully CCW the volume is normal as I rotate clockwise in the middle I get a bit of volume drop at full CW its the same as when fully CCW maybe the pots bad?
I'd really love to get working like it should ANY ideas besides throwing against the wall , finding another hobby, or moving to Siberia is really much appreciated. Almost everyrhing I know about building boxes and electronics has been learned through forums like this so thank you everyone.

I find throwing a boost in front of it helps trigger a more pronounced effect. Also where are you setting your intensity, attack and decay?

Great idea I’ll try that. So your build doesn’t have a very pronounced effect by itself ? I have spent a few hours twiddling knobs and tried settings suggested but still little effect. I’m thinking 1 - I haven’t found the right combination of IC chips or 2- my expression jacks are the wrong ones (I used the Tayda plastic switched jacks )but I’m thinking maybe they’re not isolated. I actually have some isolated ones I had for my AION board just waiting on a couple of parts to finish that up if I get that one working maybe I’ll find some answers there even though they’re a bit different it’s the same effect thank you for the help

mine does have what I would expect it to do, but for me (and I think lots of others) to trigger the envelope it very much depends on the settings. I can send you a video of how mine sounds. I don't have a YouTube account or any other social media to post it on, so shoot me a pm and I will send it over. Also I do think according to your build docs the deadendfx must have insulated jack for the intensity jack you cannot use the ones with the metal barrel unless you wrap electrical tape or something around it.

2nd and prettier but no less wonderful than Ugly Sack is Meat Sax and now to have some with loops. Don’t judge it’s seriously my 1st time trying something in a loop now I got 2 of em

And lastly they sure are a funky finicky my way or the hiway take your time with my knobs kind a pedal but so worth the time given on to looping…………..!!
