CD4049UBE for Insanity Box

[Vit]

Hi everyone - I am newb (not a complete one though:-) and this is my first post. I am excited about bulding the Insanity Box as I am huntning for some extreme distortion (ala Damageplan, most recent Exodus).

I serched SmallBear for CD4049AE but they have only UBE type and say it is for Insanity Box and other distortions. I read the comments from Jack Orman and GFR and still did not understand whether I should shop for AE type for sure. The text below the schematic for Insanity says AE was used originally.

Has anyone tried both AE and UBE and can tell the difference in the sound (more agressive, less agressive, low/high end loss, etc.) ?
Any parts to be changed in the currently posted schematic if UBE is used instead of AE ?

CD4049UBE is exactly the correct chip, the "UBE" is important. this means "unbuffered"
I've built the Insanity boz/Hot Harmonics/Craig Anderton/Red Lama with this chip and
it works fine.
Mine were also from smallbear.

I have not had any CD4049AE's so can't tell you what the difference is, if any

Thank a lot pal !!! That's releaving to know this. Now I can go ahead and order the parts !!!

Is it really as insane sounding as being described ?

It's a good build.
I did it a few month ago and think it's one of my best od. It's not a MT2boss type of sound but it's almost
a kind of od and fuzz mixed together

(i use 4558 4049ube and 2n5457)

I've built it with a schoctave down in the same box it's awesome big distorded octave down...you can see the pix on the pictures page (the ugly stuff that's it !!)

Welcome to the forum. 

The "UB" part of the part number stands for "Un-Buffered". Back in the 1970s, the early 4000 series CMOS chips lacked buffers and had a suffix that started with "A". The later chips added buffers and with them, a "B" for buffered in the part number. The "UB" convention has replaced the old "A" for the few chips in current production where not having a buffer is an advantage. The remaining letter or letters denote the package and/or temperature range and these codes are specific to the manufacturer.

A huge "thank you" to you guys for the enlightment. Hope I'll be able to share some useful advice as I become more experienced in this area - and certainly will. I'm reading up on stuff and try to practice as much as time allows.

Goodluck !!!
