Title: Mutron III & Univibe (added video)
Post by: brejna on February 02, 2015, 11:32:58 AM
Hi guys, it is been a while since I've post build report. Here is Naughty Fish with uber switch from Thomas and mine take on Univibe with relay switching.. :)

Love them both!  Great idea to include the relay switching right on the PCB.

Thanks guys, idea with the univibe was to reduce offboard wiring and make more reliable switching.. Switching is taken from Thomas.

Brilliant builds brejna!  What kind of decal material did you use on the Naughty Fish?  I've only done etches and waterslides so far, but would like to get into colours.  Not sure what kind of decal to use though ...

Both are fantastic.   Nice relay implementation on the PCB too.

Some really tight builds you have there. Not much room for error in that Mutron III. That face plate on that Uni looks fantastic.

Thanks guys, these two were builded with little bit more care then usually. I am pleased with final result :)

I've used plastic film for naughty fish. Near my home there is print office that is doing all kind of printing, so I went there. It is black plastic film with applied colours on it.

How do you find the speed range with the B 100 K pot (compared to a C taper)?

It is mostly usefull from half to the fast speeds. Below half it has only very slow speeds which no one uses. But I think that in live situations it works great, with smaller adjustment you get nice change of rate. Btw I've used 2k resistors instead 4k7s, so overall effect is faster. I actually never build univibe with C100k pot :D

Amazing stuff Brejna as always. Tight as a snake's ass. Both of them are outstanding but having heard your univibes before I am very excited by this new one that's done on your own pcb layout. Every video of yours that I've seen showcases a very FAT univibe sound that personally I am still yet to come close to. In my book, you're a master univibe builder. Hat's off sir.

Hey Cortex, univibe is my favorite pedal of all. I've made quite a few and did experiment a lot. BTW you know the secret of that fat sound I hope you'll get there :) and thanks for the title :D

Thanks for your replies on the details, another question I have is which LDRs did you use and which one's work best for, seeing that you've built a bunch of vibes?
Do you match LDRs?
Do you always point the straight at lamp and do you use a light shield ultimately?
Sorry for all those details, it's just that I dig univibes as well... ;)

It definitely became my favorite modulation effect as well, although I am a phaser guy primarily.

You are welcome. :) I use LDRs from ebay, they are marked GL5549. I think that they are not all same out there, but you can try from different suppliers. I do use very primitive way of matching them. I connect them to DMM and measure resistance in light and dark, beside that important is time of changing resistance between dark and light, shorter-better. My first build was with random picked LDRs and it did sound great. For these LDRs I always face them to lamp and I don't use shield for them.

Awesome, thanks for advice. Will check those ebay LDRs out, so far have used Smallbear ones and like them, but don't have any other comparison. :)

Stupid question to the vibemaster:
is there a rule how you setup the trimpots?
i setup the OFFSET at half, turned down the INTENSITY pot and adjusted the GAIN pot until the lamp was dimly lit. then i played with the OFFSET until i liked the sound.(built the harbinger)

Vibemaster: "That depends a lot on the type of the lamp and LDRs. Usual setup is with everything max and try to get slow speed intesity best you can. When you do this, higher speeds could be bit assymetrical but when you back intensity they'll be more round. If they are to sharp back offset a bit or try to add more light with a gain trim."

I have been on the fence for a while and I think your demo pushed me over. I think my bass rig needs one.

Post by: Cortexturizer on February 04, 2015, 11:44:51 AM
I've found that there's definitely a sweet spot that's almost unobtainable by only setting the offset and gain trimmers, you gotta factor in the "two 100K resistors mix" as well. It was only then that I've found a setting that I was satisfied with. The Vibelord will probably confirm but my experience is that the lamp should never go fully off (not even close actually) and you don't really need the gain that high actually. It really is a finicky setup in the end, but well worth it.
