Is there a volume swell pedal?

[skiraly017]

Not a volume pedal and not a Boss Slow gear (not smooth enough). A pedal that had a knob that controlled the speed of the swell and another that set the volume of the swell. Think Van Halen's "Cathedral" for the sound. Does one exist? Thanks.

yes there is, there is one on, this one has a momentary push button that controls the swell. it can be found here:

But there is no schematic or layout or any indication of either though , so perhaps the schematic can be found somewhere else.

I like swell pedals, heres what I've heard about:

EH Attack Decay: its compelling, but is both extremely rare and complex enough I've yet to hear of anyone cloning it.

Hate to say it on a DIY forum but the Line 6 DL4 does it best of what I've tried.  You can adjust the speed of the swell too, unlike their Echo Park pedal.  No volume control though. 

For slow swells, the old volume knob pinky swell is reasonable.  Economical too.

Theres a Morley big chrome pedal that has a metal guitar pick on a cord attached to it, that supposedly works great by design.

There's an old (DOD?) pedal that is like that, you press the button and it swells.  Tedious, but reliable.  I'd like a version with a couple buttons for different swell times (maybe even no knobs, then!), and forget about true bypass and leave the thing on all the time.  It'd be great for lapsteel...

Could you mod or alter a trem pedal to do volume swells?

[handwire]

i'm breadboarding a circuit that works as sweller or increment the volume to a certain position by hitting a momentary switch

I expect so, think of it this way, most trems are really voltage controlled amplifiers controlled by a LFO or else led/ldr based.
So if instead of the LFO you have a manually (ok, PEDally!) triggered ramp voltage and use that as a control instead, there you are. Which is what is being done in JC's unit referred to above.

Quoting myself from the original post - "Not a volume pedal and not a Boss Slow Gear (not smooth enough)."

  Done searching for a Tremulus Lune shcmeatic for a while.
  Start with the Tremulus Lune.
  This has many controls, volume of swell can be VC. [close enough].
  The speed control pot could be made to be treadled manually [don't know the song or how Eddie varied the rate of trem, foot controlling it?]
  An LFO 'Speed control control' could be made out of LDR's, with a separate LFO...auto ramping the speed up/down. Never done it, etc.
  And that'd be tricky sounding too ! Hopefully not ticky sounding.
  ahh...>if, you could tap an LFO for 1/2 or say 1/16th it's speed, then use that on the T.L. LFO to control the LED's controlling the LDR's which control the speed.
  ...ie a fraction of the LFO speed doing the tremolo could be used to control the speed of the trem at a fraction of the trem speed...
  Whether this can be done is another matter for the LFO Savvy, particularly dividing the LFO Speed to be used as another controller to drive another LED/LDR.

I've manually synced a trem and a delay to get that *Cathedral* sound, but the simplest, most flexible and musical way to get that effect is to use the volume knob on your guitar the way EVH did. You can use a volume pedal, but I've never been as pleased with the results. Note that delay is also key for this effect.

How about building something like the Anderton's envelope follower in EPFM, or the Dr. Quacky style envelope follower and using it to control a gain stage?

[oldschoolanalog]

Go to the moosapotamus website, and check out Stompboxology Vol 13 #4. This issue is on envelope fx. There are some attack circuits there you might find of interest...

IIRC, that was all pinky controlled guitar volume knob swells + delay. At least that is how I do something similar to it: pinky volume swells plus delay set for dotted 8 repeats (so the delay repeats occur in between the natural notes), delay tempo is set by tap.
