FLANGE/PHASE STEP SAMPLE/HOLD ?

[luknfur]

Only had effects in Mult-effect units so no independent stomp boxes. Something I've noticed with them when using flange or phase (probably some others as well) is that I liked the tone in one particular portion of the sweep but not the others.

Are there any controls on these independent boxes that allow you to "freeze" the sweep? That sounds like what the step or sample/hold units imply but in what little I've ran across about them doesn't sound like what they do.

How a flanger works, is like play two reel to reel tapes at the same time then slowing down and speeding up one of the reels by playing with the tape flange. It creates a moving comb filter.
If you were to stop at some point, it would be like a small delay. Try just using a very quick slapback delay with no regeneration, It might at some point give a comb you're looking for.

"Sample and hold" has taken on a particular meaning in synthesis, where a noise source is used, and a sample-and-hold circuit samples from the "random" voltages of the noise source on a regular basis to create a random-sounding stepped pattern. The only pedals I know of that will allow you to pick one "step sample" and hold it as long as you like, without a cycling pattern, are the ZVez Ooh-Wah filter and Ring Tone ring modulator. Although I wonder if the Studio Electronics ModMax filter or phaser have that option... I don't know. I'm not aware of any off-the-shelf flanger offering that option, but it could be DIY'ed by replacing the LFO control with a steady voltage controlled by a pot.

for a phase shifter just turn down the rate and the depth and then move around the frequency know.

Exactly. For the flanger just turn the width to minimum and set the manual knob. This creates the 'Filter Matrix', a prominent effect on EHX's Electric Mistress flanger and it's reissues. No mods required.

But if you want to have a pedal, where you could step on a switch to stop the travel up and down at some point - I haven't seen any flanger or phaser with this feature yet. A Sample and Hold circuit could do the trick, but I am certain there is an easier solution for this.

Appreciate the responses.

Actually it doesn't have to be a typical toggle stomp box, just seems like most the independent effects units (flanger whatever) are.

EHX Worm. Stops the LFO.

Also, on the pigtronix EP-1, in EF mode, turn the sensitivity down and use the sweep setting (and resonance knob if you have the marv mod)

Amazing after grit. Huge buzz saw tones.

On the Eventide Modfactor, there's a Brake switch that does just that. You hold it down to brake, then release to resume normal operation. Also, just stepping on it momentarily toggles between fast and slow speeds. I've really been digging their stuff lately - very intuitive.

A few ideas.

For phaser:

Moogerfooger Phaser, you can turn the LFO sweep off and choose any frequency you want the phaser to stay on via the sweep knob. This can also be controlled with an expression pedal.

EHX Stereo Polyphase, on expression mode, disables the LFO and you can use an exp pedal to choose anywhere in the sweep to leave the phaser.

Foxx Foot Phaser, on manual mode, just rock the treadle to wherever you want the phaser to sit, and it will stay there.

For flanger:

EHX Stereo Electric Mistress, the rate knob below 10:00 puts it in "Filter Matrix" mode, which is a frozen flange. The rate knob controls the frequency that its frozen at.

EHX Flanger Hoax can do the filter matrix thing as well, by bypassing both phasers and putting the delay mode on DC. Then just tweak both delay amount knobs to find the frequency you want.

Toadworks Barracuda can be manually swept with an exp pedal, so you can freeze it wherever you want.
