Hey everyone, hope all is well. I'm just diving in the Source Audio waters, so I'm barely scratching the apprentice level at best, though hoping to become a sorcerer one day. I picked up a Spectrum from the classifieds and have been completely over the moon with it. I'll describe why below and also will list what my envelope filter journey has been like thus far, for posterity and anyone on similar quests. Apologies for the length of post.
These are the filters I've had, not counting ones I've demoed in stores (what are stores?):
MXR BEF
Mutron Microtron IV
Emma Discumbobulator V2
Smokin' Amp Co Mutron V clone
Aguilar Filter Twin
Mr. Black Fwonkbeta
Broughton Joshwah
3Leaf Proton V3
...and now finally the Spectrum
There was a thread recently about the Mutron sound that I participated in, so I'm
linking to it here as an FYI for anyone who wants to check it out. Here are a few reasons why I traded or sold the ones above, along with changes since my post in the link, which have stayed and why, and finally my thoughts on the Spectrum.
BOLD = still have it.
First thing: funk is my happy place, so filters are my home. I play passive basses with flats and don't slap/pop. The music I play is definitely funk-influenced with many sections for group improvisation. Okay, with that out the way, here we go:
MXR BEF -- I traded the MXR because it was bandpass and because it could only give variations on one type of sound. It was good, but not versatile.
Microtron -- Returned because I couldn't get it to trigger. It was really strange and disappointing. Called and emailed them, worked with the internal trims, added a booster before it, and nothing. Still bummed out about it, but it had to go. Aaaaaargh.
Emma -- Had it for the longest time and loved it. Main issue were its size and noisiness on the downward sweep. It also wasn't rude enough to my ears.
Mutron V -- Lost low end and didn't snap the way I wanted. Other effects didn't sound good through it either. I gifted it to my guitar player and he loves it, so it just may not be good for bass.
Filter Twin -- Sat great in a mix, easy to set up. Not particularly rude. Very versatile.
Fwonkbeta -- Seriously rude and very peaky. Having a comp right behind it is a must. I love its tone and how nasty it can get. Can also do the low-pass Laswell kind of sounds. Really great, with simple controls too.
Joshwah -- Easy to set up, fantastic, very wet sounds. Wish the gain could be controlled by footswitch to kick on at any time, also wish there were a downsweep. Still, a lot to love.
Proton V3 -- A little harder to set up than the Fwonk and Joshwah, but truly great dirty quacks. Downsweep is great. Everything I put before it (octave, fuzz, dirty boost, OD, bit crusher) sounds fantastic through it.
Spectrum -- What's extraordinary about the Spectrum is ease of use. I'm not exactly a luddite, but definitely prefer playing to tweaking (yes, that's a false choice, but for me, the more options I have, the more I want to experiment and the less I write/play). It was really easy to get it to trigger, sounded fantastic with anything before it. At first I was concerned about the ALT controls and "knowing" their last place, but really I forgot all that and just started playing and adjusting knobs until it sounded right to my ears. Then I stopped and toggled across the different presets, and the same knob settings sounded great with each preset. THAT'S HUGE! (i.e., more playing, less tweaking!).
The Dumpling preset is straight money. I put a flanger behind and was in instant Mike Gordon territory.
I stacked an overdrive in front of the Tron preset and found myself in Night of the Thumpasorus Peoples.
I wasn't a huge fan of the Thrust setting nor the secondary ones, but that's where the Neuro app comes in. I haven't poked around in there yet, though I'm hoping to soon. I imagine a midi controller (is DMC Micro the easiest for a single pedal?) is in my future, to more easily access any preset and going beyond the six.
Anyways, this was very long, hope it was helpful to anyone on the fence about the Spectrum. It's worth it, and it rips.
