Need help with Kemper's tremelo effect

  • I've tried dialing in the onboard tremelo, but I can't get anything but a soft pulse effect. I've got the Depth setting maxed at 10, but I can't get any type of clean start/stop effect, like most trems can do. I've tried all the other settings, but nothing is working.


    Anyone have any experience with this? I really need this effect for a song my band does, and I do NOT want to have to bring a separate pedal. Hopefully there is another adjustment I can make.

  • What exactly are you looking for? Like a hard square wave type of on/off tremolo?


    Yes Will, exactly that. I should have said square wave.

  • I have already posted a feature request for a "chopper" effect, but it either hasn't been paid attention to or hasn't been a priority thus far. Maybe if enough people comment in this thread? It should be a fairly easy effect to add to the KPA.

  • Yeah, it's not the best for that type of hard stutter effect. Maybe someday they'll add it.


    I'm open to any suggestions that will improve it in its current state ;)

  • The 'hardest' I can get it (ooer missus) is to put the depth at 10, crossover at minimum and then put the stereo at 0%. Rate as required by the song. But, it's still pretty polite compared with some out there.


    Doing this, it's still not a square wave thing and it does not kill the output dead.... it's then more like and opto trem.... If you set the rate at minimum and hit a note, you'll see that it ALMOST kills it in the troughs but not completely and it's going there and back pretty softly. I like it, but it's more 60's spy movie rather than an extreme jitter.

    +1. I would add it needs to be after the amp as well and it's darn choppy, but not the pure square wave stuff you can do some effects boxes today.

  • The Tremolo is pretty weak altogether IMHO. What it does is just modulating volume. A tremolo like in an old Fender on the other side would work by varying bias and that seems to have some side-effects other than just the volume going up and down. I'm not sure if such a thing would be possible in the KPA since that kind of thing would have to be wired in the ampmodel itself.


    But anyway, I really wish for an improvement, I miss the fucking cool tremolo of my old '62 Deluxe so much...

  • I'd love to see some more patterns for the tremelo effect, even if it's just the option of a square tremelo.


    Actually you know that? Scratch that, these guys created the Virus fercryingoutloud, lets step it up a notch! I'd love to see a unified LFO option and interface for all effects that make use of one, that would give you the normal range of LFO's you get on a synth as well as bias, depth, speed. It would be great on not just tremelo, but also flangers, phasers, chorus, pitch effects, filter effects like autowah etc.

    not completely true, since AFAIK Fender incorporated three tremolo types: opto, bias and harmonic.
    the one with the most side-effects was the harmonic one.

    You got me thinking what type of trem my '62 Deluxe had. Looked it up and it was a bias trem (power amp tubes). Todays Fender trems (opto?) are not that interesting, IMHO. They sound as boring as the KPA-version ;)


    So can we have something with the side-effects of bias and/or harmonic trem then? ;) If that's done, I'm all for different LFOs or stepped waves or whatever. But in all honesty, if that means it has to be put in the amp-section and basic tube-model of the KPA and such a change would require significant work, I'm not sure if I want it badly enough to sacrificy other developments of the KPA ;)


    But then: We have so many fantastic profiles of vintage Fenders that are so spot on to the originals, it's a shame that the trem is not on par.

  • Digitech has had a software version of their trem pedal in the RP series for ages - and it has a great range of trem effects. It doesn't need to be tied to an amp. It should be pretty straightforward to design and implement in the KPA.
