@loylo: hmmm.. here is the data sheet schematic for your brick ( courtesy of smallbear)

https://www.smallbearelec.com/Projects/ReverbPedalSchematic.pdf

totally different pinouts etc i'm afraid, ..and its a short reverb.  

The BTDR-1 should work in this circuit BUT the pinout is different, so any PCB art will not work and it draws more current than a BTDR-2, so I would use a 7805 voltage regulator (rather than a 78L05).
The short or medium bricks will sound different to the long brick, but will still work. With the feedback working so well now, a short brick may actually be more versatile.

I can report the medium brick sounds amazing.  The oscillation switch does not actually reach oscillation; however, it does swell nicely and sounds fantastic in tandem with an analog delay.  This will probably be my "daily driver" once the click noise is sorted...

edit: I'm building a couple up off of the v1.6 RO Tiree boards.  What modification must I make to get the noiseless switching?

edit 2: R14, perhaps?

Hi deadaustranaut

I've been reading this post and Man... After ear some of the demos... Congrats... It's a sweet reverb machine that you have here...

I use mostly the rub a dub but i want to give a try on your baby...

I see that there is a lot of changes going on so my question is should I build the last file project that you post or should I wait a bit more to let all of this changes take place?

A big shout
Sérgio

Thanks deadastronaut and samhay! 

I know the pinout is different and I'd have to change the layout if I take BTDR-2 design.
I think I'll test your design, deadastronaut, so that's nice if the BTDR-1 works.

And what if I try to make your own "another BTDR reverb", samhay, with the BTDR-1?
I wonder if the two outputs of BTDR-1 would allow me to take the feedback path from the second output and work like your BTDR-2 design?

You're welcome.

As far as I know the BTDR-1 and BTDR-2 are equivalent ICs in different packages. Shrinking the package in the BTDR-2 reduced the current consumption, but otherwise I would expect the two bricks to behave the same. I may be wrong, but I haven't heard anything to this effect.

So... the BTDR-1 should (but may not) work just fine in any of the circuits designed for the BTDR-2 and I see no problem using it in my 'Another BTDR reverb'. I would be interested to hear your experiences, and would encourage you to try it on the breadboard first.

i have designed and made a pcb, and gone over it carefully for any errors, but all checks out..  

populated it now, am just finishing up wiring/and 1590bb box etch design .....then test it thoroughly.

bought a couple of nice ALPHA non clunky DPDT footswitches, so should be nice and quiet...

i'm busy today , but should be done by early next week...hopefully...

if all goes well i will make a batch of pcbs available ok...

note :  due to the recent 'brazillian ripping me off' incident, i will only be sharing a link to the layout files by pm only...as i'm @#$%ed off with doing months of hard work
only to be taken the p.ss out of, and seeing that hard work used for commercial purposes  and even my video demo's too for @#$%s sake  ,
even when i ALWAYS state ''not for commercial use'' ...sorry but that's the way its got to be, as some @#$%ers don't seem to understand that phrase...  
rant over...
back soon with results..

Put me down for one.

Will definitely need to pick up a PCB, only thing my pedal board is missing is a good reverb! Seen poodle has some bricks in the UK, might hold off on getting his PCB and try this one instead.

Good news then... I want one... My favourite effect

Eu quero um também.

fair enough Rob. Are you going to post a final schematic?

I hope this doesn't derail this thread but I just have to mention it and seems like the place to ask.  Has anyone built something from one of these before?  16 effects in one, includes the reverb effect im assuming is the same as the one we are hearing with the flying saucer reverb:

http://www.accutronicsreverb.com/ (link is on the left hand side, BTSE-16FX)

The example circuit looks suspiciously simple

Hmmm, this could use a new thread perhaps...

Here's a direct link to the PDF:

http://www.tubeampdoctor.com/images/File/BTSE-16FX_%20Accutronics%20DIGITAL%20SOUND%20EFFECTOR.pdf

Culturejam mentioned no user controllable parameters (in another thread), which sucks abit but I would still be interested hearing it in action.

This should probably be a new thread.  The "Flying Sauce Effector" thread?    Sorry rob, ill leave the conversation here.

You're right, I'll have to test if the BTDR-1 behave the same way as the BTDR-2 is supposed to.
I'll report it back to you, for sure.

nice one!

I'll have to really get around to opening mine up again and getting that oscillation happening, otherwise I might just have to grab one of your boards for down the track

Hey Rob.. how hard would it be to turn this into a stereo reverb? The Belton Brick can do that, right?
