Could the EA Tremolo be modded to reverse the waveform?

[skiraly017]

I'm not sure I'm even phrasing the question right. I'm listening to "Tied Up And Swallowed" by The Black Crowes and the intro riff sounds like a tremolo doing its thing backwards so I was wondering if the EA Tremolo (or any tremolo) could be modded to wave/sweep/trem in reverse? Thanks.

Hi
the EA trem has a sine wave oscillator.  Backwards, that also a sine wave, so it would sound the same.  Some trems use sawtooth (slow rise, fast fall) and similar oscillators.  These would sound different if reversed (ie swatooth "reversed" = fast rise, slow fall).
Is that what you mean?

Nevermind, I just realized Rich is doing volume swells.

Slow Gear SG-1 might work for this.

So would a good volume pedal.

I don't know if this is possible, but maybe varying the pulse width of the LFO might be kind of interesting. Then you would in theory have alternating rises and falls.

I stuck a cap to ground just before the depth pot on mine.  It yields a different feel, particulatrly for faster speeds.  I'm wondering, would it make sense to stick a diode inseries with the cap to produce such filtering in only one direction of the sweep, or is the LFO something that does not go above and below a reference voltage? (i.e., there IS no "other direction").

If that worked, I would think that it could be something like a "stuttering" pedal.

Every waveform goes above and below a DC value in between it's peaks... For example, a sine wave going from 3V to 7V would have it's "reference voltage" as 5v - it's basically just the same as your ground, except this "ground" is not the same as the earth "ground".
