I jumped on the Source Audio wagon with full force and, overall, I wish I hadn't. There is only one exception.This pedal is absolutely great. It really shines on lower frequencies which lands it on my bass pedalboard instead of guitar, when I actually bought it for guitar. Man does it really shine on the bass though.The problem I have with most Source Audio pedals is that the settings and presets are absolute crap out of the box. You usually have to do a lot of tweaking in order to get even a decent sound. The possibility is there, but it's more work than one expects. This pedal is again the exception.The Spectrum sounds amazing right out of the box, there's also a ton of tweaking headroom for more sounds, and it can be controlled with an expression pedal for ... MoreI jumped on the Source Audio wagon with full force and, overall, I wish I hadn't.

If the Aftershock is the Swiss Army knife if dirt,Lemme introduce you to his funky sibling, the Spectrum.Does a little of everything and it’s entirely possible to get, Rotary, Trem, Chorus and Phaser from this box AND THEN you’re treated to the Envelope and Octave options.It Fwonks, it honks, it quacks your only limitation here seems to be your imagination.And rhe neuro app has so many good sounds for this guy.

Never had so much fun with a new pedal! Sounds are awesome. Coupled with an octave fuzz it's insane! Over 200 for a pedal you may only use occasionally may seem like poor value for money but it will always put smile on your face.
Best filter I've used thus far. Great tracking and lots of funk in this box. The octave down bass simulation is brilliant. Only recently discovered Source Audio and they make stellar products.
Actually its not for me, I gave it to a loved one. And he is so satisfied when he used it. Thanks!
This is best sounding envelope filter I had played. Super smooth out of the box, but you can go real deep.
I first and foremost got the pedal to cover the classic Mutron envelope sound, but the option of having five additional sounds was super appealing. The Tron preset is awesome, Easy to dial-in,and exactly what I was looking for. I was really blown away after connecting the pedal to the Neuro software and being able to listen and download tons of users saved sounds. I very easily reassigned several of the presets, and Im just blown away by the ability to edit a pedal that way. Needless to say I am very happy I got one.
Great funk machine for my bass! Once you figure out the neuro app you can download different sounds and edit as you wish! Plug into phone and Boom! Many different wahs in one purple box! Get it!
Envelope filters and so much more this is a great pedal I've owned them all and this one's my favorite.
