So I am working through a project for a friend that wants a combo OD/delay/reverb build. Problem is he doesn't like the accutronics-based circuits that we have tried (i.e rub-a-dub or tenebrion reverbs). There is that modulated echo in them that he doesn't jive with. Short and long bricks both have it.
So...
Any other reverb projects worth trying out there that offers a smooth, non modulated reverb sound? Anything not accutronics based that sounds good?
Also: He actually he likes the "plate" verb on his Boss RV-5 pedal. How much of a PITA would it be to re-house it with off-board pots and true bypass into the combo build? Anyone done something similar?
Thanks for any insight
The older larger bricks don't have the modulation (at least not that I could hear). Maybe try one of those.

Thanks. So do they also have more of a natural verb sound? The small bricks sound more like a washed-out delay with distinct echo repeats you can hear.
Also, the BTDR-1 has different pin configuration correct. Would require some off-board wiring to vero I suppose? Looks like they have 7 pins instead of 6?
Just use a pcb or project that supports the old brick, there's a few options...
The FV-1 is a pretty cool plate sound...
Obviously not to privy on reverb projects.
What pcb/project is available for the larger BTDR-1 brick?
What about this FV-1? surface mount chip I assume? Any current projects for it?
Brian just posted notice of an upcoming etchable board for the FV-1: http://www.madbeanpedals.com/forum/index.php?topic=12287.msg117252#msg117252
There's also the SKRM daughterboard, which is FV-1 based: http://www.experimentalnoize.com/components/skrm-c8-xxx-reverb-effects-module/

I stopped reading here :)
Seriously...ahem. Did you try a long or short reverb? I have heard that the short brick doesn't have audible repeats. Don't quote me on that though im pretty sure that was one users experience.
Well the rubadub has the short brick and the tenebrion has a long brick. Both of them have a characteristic slapback delay and modulation in them (although the long-brick is more pronounced of course. FWIW, I also built a rubadub with a medium brick once and it had the same issue/characteristic.
I really think it is just the nature of that brick but what do I know?

More then me Pryde, ive never heard all 3 :D
I know what you mean, but I've really never heard the modulation on a short brick rub-a-dub and I stand by it as being the nicest straight reverb out there. I've certainly not come across anything in the DIY domain better than the RaD and Tenebrion. If you want to reduce the modulation to a minimum, you've got to use the short bricks though. It's more apparent the longer the brick.
FWIW I've tried all bricks ;) I prefer the Med/Long with the more apparent modulation in the Tenebrion and the shorts for the Rub-a-Dubs.
This was recorded with a Rub-a-Dubs with a short brick.
How about a short brick in the tenebrion?
It still should sound a bit more spacious than in the RaD because of the feedback loop maybe? Anyone do a short brick tenebrion?
Personally I like both the RaD and Tenebrion. It's just my friend is damn picky :)
Maybe he needs an EHX Cathedral? (Although those are damn pricey.)
I am actually thinking about re-housing some kind of pedal circuit in there for him. Space isn't an issue as it will go in a 1RU rack enclosure. That cheap biyang RV10 reverb actually isn't to bad sounding and might be a good one to transplant? Not sure though if it will be to much a pita.
If he wants better than a brick, he's going to have to go full digital.
Yeah I agree with juansolo. I reckon your friends request is out of the diy field. He should just buy a Big Sky or something. Expensive, but as you said Pryde, he's being picky.
Thinking I might try to re-house a biyang rv-10 into the effect as he seams to like the reverb it produces.
Will need to run new pots off-board to the face of the rack unit, then figure out 9v, ground, in/out on the pcb to run to a new 3pdt toggle on the face as well. I think he will settle on 1 internal setting (toggle switches on the board).
Not going to worry about the stereo in/out options, just going to use the mono path. Any issues/problems with this approach?
Not sure Pryde, but I was wondering, what chip does this effect use for its reverb effect?
Should be pretty straight forward. I rehoused a Danelectro pedals last year and it was just a matter of removing their pots and placing mine and I converted it to true bypass. Nothing to crazy.
Chip is 3201 processor in the unit. I have only heard demos but it sounds pretty decent for $50 I think

had a quick look at the datasheet, unfortunately way above my head. Looks like some digital programming involved. (AL3201BG)
the old bricks dont have modulation? wow! I wish theyd make the new ones without modulation in all the different decay times.
I can attest to the fact that the short decay time has less modulation than the long- quite a bit less.
And id also like to note that the decay times have nothing to do with slapback echo in my experience. you can get it to slapback with any decay time. just depends on the circuit implementation
Yeah bear in mind the delay times aren't massively apart (200/250/280ms IIRC).

That's the same chip as in the Dr. Scientist Reverberator. You could build something relatively similar with the Femtoverb project, which uses the AL2013 also.
Brian and I also worked on a basic FV-1 project (some time ago), which I presume is what he plans to release in the near future. As we left the project, you have access to all of the on-board programs that come default in the FV-1, a few of which are reverbs (and they sound pretty damn good).

its actually
2 seconds
2.5 seconds
and 2.8 seconds
not ms
and those are decay times, not delay times
If the old style large bricks don't have the modulation than Earthquake Devices Ghost Echo would certainly be different between their big box and small box models. Hmmm....

My *recollection* is that the big/old bricks do not have modulation (or not nearly as much). I built a few of those and never noticed modulation, whereas I immediately heard it when I fired up the first small brick build.

Indeed! I sit corrected.
