cool reverb apart from switch spdt 'pop' issue

[deadastronaut]

no, you could still have oscillation, just swap the 33k for a 22k/ maybe 10k..... (without a switch)

or if you want a switch have a 33k and 22k/maybe 10k on outer switch lugs...and connect switch middle lug to board (where 33k was)

and run both resistors to other side of where 33k was....

Well... I etched another v1.6 board, and was very careful with my soldering (those little traces take patience, and a thinner diameter solder I realised) and now I have one with oscillation.. hoorah!

whoooooohooooooooooo merry xmas...

whoooooohooooooooooo merry xmas...

My new amp (merry Christmas indeed!) doesn't have any on-board reverb like my old one did, and I really love the everything at 100% sound of this reverb for atmospheric picking (which would be really appropriate at times in church - but gets woolly for strumming and driven sounds) but then the reverbless sound of the amp when I bypass it is quite a shock.. so I might have to build another simpler 'always on' reverb..

But what if we could route the belton to two different sets of pots with a footswitch? The easy way would be to simply have two independent reverb units in one box with a switch between them or two bypass switches, but those bricks are not cheap.. is it even possible to swap the brick between two output circuits via a footswitch? (of course, the other option is to simply get down and twiddle knobs, but that's impractical during a set).

[deadastronaut]

anythings possible i guess...within reason....do you mean having 2 preset pots..switching between?

on what pot though...the reverb level? 

[therealfindo]

Ah, what the heck.. I'll just build a V2 - buffered w/tails - to go after it at the end of the chain! 

[deadastronaut]

 best of both worlds...

Is the dry part of the signal still analogue? (just out of interest..)

Hey guys, could you take a look at this schematic? http://efekty-diy.pl/pdf/Reverb.pdf
I've build one but Im not quite satisfied with the quality, is there anything I can do to improve it? My reverb is only usable in first quarter of Reverb Pot, above that its just really echoing and very bathroom like. It also has springy sound at almost all settings. Maybe you know what to change to make it sound more like Flying Saucer?

^above that its just really echoing and very bathroom like
If one were to be uncharitable, that is how I might describe the Belton reverb brick sound.

^it also has springy sound at almost all settings
yep - it is supposed to emulate a spring reverb, and it does a pretty good job of doing so.

^Maybe you know what to change to make it sound more like Flying Saucer?
I could tell you to just build one of Rob's (or mine) reverb instead. However, the 'flying saucer' noise (good description) is, in part, a result of less filtering and more feedback than usual.
The attached schematic has feedback via RV1. If you want more, try reducing the value of R4. It should start to oscillate somewhere around 22k.
Filtering happens via RV2 and the 33n cap. If you use a smaller cap, you will get less treble loss and vice versa.
The other thing that you might want to try is to lift the dry signal to get a fully wet reverb. This may be even more 'bathroom' like, but is probably what you are hearing in Rob's clips. To lift the dry signal, lift one end of R10.

Edit: something like this? http://www.diystompboxes.com/smfforum/index.php?topic=107226.msg974393#msg974393

Thanks for the mods! I lowered the 33nF cap to 15nF and I think now its more like it Didnt like the oscillating mod, I have plenty of reverb to go on, actually its only usable in first 90 degrees of pot. I think Ill stick to what it is. The sound Im hearing may also be affected by my Noisy Cricket MKII. Im sure it would sound better with real amp

That schematic is nearly an exact copy of the All-Star Reverb posted by induction over at the "Other Place."  I built the All-Star and thought it sounded pretty good with a lot of versatility.  I build mine stock, without the wetter mods that were posted.  I'm no designer, but there seem to be a couple of key resistor values that may account for an imbalance between wet and dry.  Maybe this one is like the "Wetter" mod for the All-Star?

I think this is the right thread - I have so many saved files called "DA Reverb <somethingorother>", that I can't be sure.  Anyway, the one before the CHASM...

Just wanted to say that I took this for a bit of a road test yesterday, doing some recording for a mate.  A small collection of my other builds (e.g. Engineer's Thumb, BSIAB2, Tube Reamer, ...) ultimately going into this, then into Rick's "Murder One" and an 8" Orange cab.  It sounds feckin' gorgeous.    My mate was suitably impressed.  Nice one, Rob. [ Aside:  Hmmm... everything between Fender/Gibson and Orange was from the Bunny-Boiler.  How cool!    ]

^It's a good 'un! 

[Xomby]

Does anyone still have a copy of the schematic for this pedal?  Whatever happened to "What happens on the internet, stays on the internet"?

[deadastronaut]

great first post... 

[Xomby]

great first post... 

Sarcasm aside, as you're the very specific reason I signed up at all, thanks!

Been working through tracking this one down for a while, and finally decided to go straight to the source.

[deadastronaut]

 

Hi xomby. Take a look at the "CHASM reverb"

Its the updated version...all info is there ok man..

[tommymariotti]

Hi Rob,
can i need a reverb for my pedalboard.
Can you send me the final version (with tails) of this reverb?
Thanx

Tom

[deadastronaut]

hi tom , so a search for  "chasm reverb" 

all docs there ok...
