    I've done my research and it seems like mutron-style envelope filters seem to be well loved on TB. I've been following this brand called VFE for a while (if I could afford it now I'd get their Alpha Dog in a heartbeat), and I noticed this:

    http://www.vfepedals.com/projects.html

    This is a page listing Peter's brainstorming ideas and works in progress, and under the "Project List" tab, I think a lot of people would be interested in his Mini Mu. Here's a picture and the info from the website:

    [​IMG]

    The first edition of the Mini Mu is a simple clone of the classic Mutron III envelope filter (aka autowah). A few extras have been added, namely a passive output level attenuator and an "in between" position on the range switch. With the included charge pump, this runs on +/-9V like the original without needing a special power supply or two batteries.

    GAIN: Controls the pre-gain of the circuit, and affects how the circuit responds to the dynamics of the input signal.

    PEAK: Controls the amount of resonant feedback in the filter.

    LEVEL: Passive attenuator to adjust the output volume.

    DRIVE: Selects between a upward frequency sweep & a downward frequency sweep.

    RANGE: Selects between a higher or lower frequency sweep range.

    MODE: Selects, between high pass, band pass, and low pass modes.

    INTERNAL CONTROL: The internal trimpot affects how the LDRs respond to the trigger circuit. This greatly affects the sweep & feel of the filter sweep.

    To give an idea of more things he does, here's a demo of the Alpha Dog, Pale Horse, White Horse, Blueprint, and Bumblebee, and here's a demo of the Pale Horse, Old School, and Alpha Dog.

    A side note: on the projects page, if you go to brainstorming, you can see some more ideas he has. The bass octave fuzz looks delectable.

    You're welcome, I need an envelope filter, this one might be it. There are plenty of Filter Fanatics on this forum, I thought they'd appreciate it.

    these are now available for preorder! i guess these are version 2. somebody needs to try one - they're priced right. Could be a Proton killer? :ninja:

    I've found a small amount of reviews for VFE on Talkbass, but the ons that I've found are ALWAYS positive. To anybody on the edge of buying it, I say go for it.
    (as long as you tell us your opinion of it ;))
     
  6. I had the Mini Mu for a while and it is voiced more for guitar but I did find some good settings for bass. I found the input gain to be too sensitive though and had to be set just right to get an optimal sound. since i like to use it clean and with fuzz in front it was impossible to find a setting that would work with both. made it difficult to use live, especially since our gigs don't typically allow for a lot of time to setup and sound check.

    here is a clip of it. just me noodling around and playing with different settings. the dirt was a dwarfcraft baby thundaa, but i don't remeber which bass i used.



    listening back, i kind of wish i kept it and experimented more with it....I have a proton on the way, I'm hopping it is not as sensitive..

    Wow, (literally) that is actually what I'd want in a filter personally. Thank you so much for the clip!

    I don't own any VFE stuff but I almost bought one. The guy who owns the company was VERY cool and extremely helpful in answering my questions.

    Oh yeah I'm the same. I've been wanting a Distortion pedal and Peter has been AWESOME about answering any questions I have.

    Peter emailed to say he'll be sending me the latest version of the White Horse for review sometime soon. :)

    Awesome! I was thinking about getting that, I need a comp and a unique overdrive would be cool.
