    So I'm doing the standard thing of fuzz > resonant filter (Xerograph) to get a synthy sound. With the resonance of the filter set high, you obviously get more bass when the cutoff is low...

    does anyone have any tricks for maintaining the lows wherever it's swept?

    so far I've tried another static filter (set to a low frequency)in parallel, but that sounds a bit woolly and phasey; I'm not so keen on clean blend, but a compressed clean blend works better. have a few more things still to try.

    My best results have come from using a soloed octave down in parallel with the swept filter.

    I think the sound you want is usually done with a lowpass filter, with or without
    a resonant peak.

    What filter types do you have available?

    I should probably invetigate that a bit more. I do have a Meat Box kicking around...

    I've not considered it so much as I usually play BEAD (or even F#BEAD) so I feel octave below that might is a bit far.

    What I'd quite like is a pedal that generates a sinewave tone at the frequency of the bass, rather than an octave below!

    I have a Xerograph (2- or 4- pole lowpass), 3Leaf Wonderlove (2 pole lowpass or bandpass, although its sweep range doesn't go all that low), and a Boss FT-2 (I think it's a 2 pole lowpass as well, could be wrong).

    The fuzzes I am using are Mammoth and Death By Audio 'Soundwave Breakdown', both of which like to be the first thing in the chain, which cuts down my options a bit. I did try an Oxide but didn't find it could do what the mammoth can.

    You could split your signal high and low and effect the highs only. There is a pedal to do just this but I forgot the name. Probably FEA have one.

    I would definitely recommend a dual-band setup, because then you can have two separate filters, each with their own cutoff point, covering two different frequency ranges. It's an outrageously Bootsy sound.

    But a clean blend also works quite well, for a less extreme (more natural) overall tone.

    The sfx X&M is kind of a combination of both approaches; I haven't actually tried it yet, but it's a great idea.

    I like the idea of splitting the bands first, will definitely consider getting an X&M.

    The clean blend approach appeals for simplicity, as you obviously have a lot less HF in a clean signal than a fuzzed signal - but it's a bit problematic as neither of my fuzzes are as happy in a blend as they are with a bass going straight in (though now I think of it I should try in a passive blender too...)

    I did get a good overall sound splitting the output of my bass just with a Y -cable, although some of the output of the mammoth fuzz sound seems to leak out of its input into the clean path.

    The closest sine wave-esque sound I've been able to get is with a static LPF with the cutoff frequency pretty low. Filtering out all of those upper harmonics gets you just a pure fat bass fundamental. Try doing something like this and running it parallel to your swept signal.

    I stress parallel processing because layering basses is a huge part of modern EDM and electronica music. Most times it is a clean sub bass running parallel with a distorted/sweeping/detuned/etc.. signal.

    Here is an example from my soundcloud page. This is running the OC2 in parallel, but can sound the same with a regular signal with low pass filtering applied. The sweeping starts at around 2:05:

    That's been my 'plan A' - not all that enamoured with the resultswith the filters I have though. Would love to try two 4-pole filters in parallel.
