Bass pedals, please: Compressor, Octave (below), and envelope filter.

I have recently switched from guitar to bass, and would like to build pedals specific to the bass. After playing my first bass gig in the French Quarter last weekend, I realized I need a good compressor that has attack and decay controls, and most importantly, a blend control to keep the low frequencies intact and clean. I need something to limit the volume on the loud notes in order to preserve the structural integrity of the old architecture.  ;D

An example of what I would like to build is the new MXR "Bass Compressor M87." The new LED on the M87 is cool, but not necessary. I will likely end up buying this pedal, like the MXR M-80 I bought last week, but I'd also like to build this pedal.

I also like the MXR "Bass Octave Deluxe M288" and the "Bass Envelope Filter M82," as both of these pedals not only sound great, but they are very versatile and have a small footprint. These are GAS pedals, so I will likely not buy them, but rather build them instead.

Fuzz/Distortion/OD pedals can be made using several existing Madbean projects, though it would be nice if all the project pages included the bass mods explicitly (some already do, thanks Brian).


es là-bas!!

I don't think that you'll get any Bass Octave Deluxe M288 layout any soon (they are full of bunch SMD's and that kind of shit and i think it ain't easy to hack them IMO), only if you'll have any luck like i did. My MXR El Grande Bass Fuzz broke, so i brought it to the service, where guy after fixing it gave me an original MXR schematic "in case it die again". ;D
If you're interested, i can give you a layout for that pedal.

Cheers,
BB

Not sure if this will help, or if it works with bass as well, but musicpcb.com just released a pretty sweet looking filter...

Forgive my ignorance, but which filter pedal is the Meat Sphere supposed to be emulating?

edit:  I mean I know it's based on the Mutron III, but in the musicpcb site they say, "It is based on a much-beloved boutique filter pedal, which was itself based on the old Mutron III filter."  I'm wondering what the boutique pedal is.

Well redbean, I've seen it now.  ;D

I watched a vid of some kid with a meatball.  It sounded great, and the kid had some nice chops.  Very cool filters.

The lovetone meatball is better on bass than guitar depending who you ask

I keep going to guitarpcb looking for it to realize it wasn't that site. hahaha Looks like an amazing Envelope Filter with an confusing amount of settings.

Not that I mind thread drift at all, but to add to the OP's point, I'd love to see a Madbean iteration of the Flipster. I dunno how the ethics of that would work out with a ROG project, but if it were cool to do that, well, that would be cool  :P
