Far Out / spring reverb pedal

[cooder]

Very nice spring reverb emulation here, and I don't say that lightly since I'm a sucker for old school reverb.
I think it does it very well and I do have a Deluxe Reverb amp clone and a ReVibe free standing tube driven spring reverb unit to compare.
Came together well on a pedalpcb.com board, the belton brick is hidden under the board. So as the Belton brick is I believe basically 3 x PT2399 in one enclosure and the then one PT2399 on the pcb itself this circuit employs a total of four of them to get a nice haunting springy reverb.

Relay bypass by 1776 fx, acrylic faceplate over laser decal as I usually roll these days.

You're on a roll, Stevo!

So do you put your decals onto the enclosure, then acrylic on top, or do you put the decal on the back of the acrylic?

Decal onto sanded enclosure, let dry, face plate on top and screwed down.
That also means I could take face plate off without loosing decal, make a new face plate and stick it back on, in case the face plate gets messed up over time.

Cool.  Yeah that makes sense. 

Looks good by the way, as always!

You're screwing with my productivity - my work day is now starting with 'what pedal has Cooder made now?'

Ha! Nice work again, as usual.

That's really sharp. I'm digging the face plate, really speeds up the process. Is that just acrylic? You should whip up a tutorial on that.

A really great series you have going here Cooder. Nice job!

Ha... the pressure is on then. What will it be tomorrow!?!

If Jimi asks for it I'll better get onto it... keep your ears peeled.

Update on this as I had it on my board for a bit:
Sounds great, however built stock it has a small volume drop when engaged, certainly enough to annoy me.
Simple solution is to increase R4 from 10K to 15K (or whatever value you find right in your setup).
15K worked great for me, seems now unity gain when engaged.

It's a similar fix as on the also excellent sounding spring reverb, the 1776 fx rub-a-dub.
Josh describes this in his build doc there and I applied this here too and works just as well.
Pedal is back on board and it's all good.

IHope that helps anyone who might build this too in case you find the same issue.

Great build! I'm wondering if the relay bypass allows for reverb trails to continue after the pedal is bypassed?

Nope.
For reverb tails it would need a buffered bypass AFAIK. Cheers.

Thanks for the quick reply. I'm about to work on this build myself and was hoping there was an easy solution to the tails issue. I don't have much experience with relay bypasses/buffered bypasses yet.

A great sounding reverb with tails / buffered bypass is the 'dead astronaut' project "Abyss" reverb, I have built that one as well: http://www.madbeanpedals.com/forum/index.php?topic=27899.0
Not sure who currently does pcbs for that, maybe Robert aka 'dead astronaut' offer some.
