Prismatic Reverb (aka Deadastronaut Flying Saucer aka Box of hall aka...aka...)

[chromesphere]

Hi guys,

Forget to post this here!  A recent, very satisfying build.  Theres a thread on 'the other forum' about it, link is in the description on the youtube page of the 2 videos below.  Fanastic sounding reverb...have a listen to it in that sound demo below.  Highly recommended!

Build Report

I was also building this on the FSB forum and I simply love it. I have yet to box it up yet but it has been connected to my test rig for almost a month just so I can play it. The oscillation switch, I think, is a must because it adds a whole nother level to this verb.

I did just pick up the Grindcustomsfx Tenebrion Reverb to compare it to.

I love the layout Deadastronaut did but I would love to add onboard pots at some point.

I have found with a "short" belton brick and oscillation up high and a LPB1 or SHO you can achieve the same sound as the new Death By Audio Sunshine Reverberation Pedal.

[chromesphere]

Yes!  That was your post in the DIYSB i followed for the oscillation switch.  I agree worthwhile having it on there.  Interesting to hear the experience you have had with th other reverbs. 

When things settle down at home i would like to try the wet / dry mod that was being discussed in that thread as well.  Only reverb would sound pretty cool!

I definitely agree.. that would be an awesome addition and I would be all over that mod also.

On a side note.. I have been enjoying your videos and would like to request if you can do some on troubleshooting with your scope. You and I have almost the same scope and I am trying to wrap my head around ways to help me troubleshoot and testing. I would love to see what you do with yours.

[chromesphere]

Thanks! Its a good idea, unfortunately theory is not my strong point and presenting that sort of information can just lead to it being picked to pieces if your not 100% sure of what your saying.  I may still do it at some point, and i have some more oscilloscope videos in the upload queue though so keep an eye out for those.

Wet/dry should be pretty easy. I would think a SPST on the output of the input amp would do the trick.

[chromesphere]

I think mike / rob (r o tiree / deadastronaut) have implemented a pot in much the same place, as an adjustable control.  Not even sure i'd be able to fit it!  That BB is filling up

is there a pcb layout for this or something?  cant find one!

Just follow this thread
http://www.diystompboxes.com/smfforum/index.php?topic=101126.0
There is 2 different layouts that are verified and another one in the works it looks like.

[claytushaywood]

well the first two posts of the layout are not available for download when you follow the link.  and the one that is available to download apparently isnt verified yet

[aballen]

Really want to build one of these.  I have such a huge backlog though.

[GrindCustoms]

Looking great! Verbs are fun to build

As far as i know, the Box of Hall is a design by CJ that couple guys pulled a variety of layout out of it...

The Tenebrion is essentially the same thing other that we added a feedback pot to control the amount of feedback.....if that control is turned completely CCW...it's a Box Of Hall....

Box of Hall was the board used to devellop the Tenebrion

[gtangas]

Very nice verb.... I have to build one of those...

[chromesphere]

You will noticed also in the diystompbox thread that rob (deadastronaut) is working on tails for this effect as well.  He has also added a wet/dry pot.  Looks like im going to have to make another one :|

Yeah, I need this. Where's the PCB art? Clay is right- dead  links.
