Comments about Source Audio Soundblox Pro Poly-Mod Filter:

WOW. That's the review in a nutshell. This pedal is incredible. I'm not kidding when I say - literally - HOURS of my life have disappeared because of this pedal. It's like a transformer - it's so many things at once. Yes, it will do the "70's Funk-in-a-box" sound, but it also has some really chewy phaser sounds in it. The autowah sounds on this dude will BLOW YOUR MIND! It's total bow-chicka-wow-wow stuff. The step sequencer is pretty great too!

Frankly, the EQ section alone is almost worth the price (it's a bit pricey just for an EQ) Even so, I think it's the same EQ circuitry as the Source Audio Programmable EQ, which makes this the pedal the best "value" in Source Audio's line, AFAIC. The pedal is also pretty big, and could easily command half of a smaller pedalboard (especially with a dedicated expression pedal).

But, in light of the higher price, you could quite legitimately take your phaser, your tremolo, your EQ/Boost, and your wah off of your board and just use one of the SIX presets on this one pedal for each sound (provided you hook up an expression pedal for the wah sounds), and still have two left over for killer LFO and Filter effects. A couple other things you might want to know: Yes, it comes with a wall-wart power supply, but it works fine powered by a OneSpot or Godlyke Powerall. I've not had occasion to use the MIDI or HotHand stuff, but they're cool features (especially given that they will interface with Source Audio's new Hub). If you want to change the LFO waveform, you have to do that in the backpage menu (which is super easy - just hit the Mod Source and Tap Tempo buttons at the same time, and the "right" button for EQ band until it gets to the far right. Then spin the encoder wheel under the EQ and you're changing wave forms. Simple!). I've been playing for 25 years, and this is one of the best values I've ever seen.

The build quality on this guy is crazy good. The switches feel smooth, but very solid. Nothing rattles or feels flimsy. The jacks make a very solid connection (can I get an "Amen" for top-mounted jacks on a huge pedal?! Digitech Whammy DT, I'm looking at you). Even though it's an expensive pedal, for what it does, and how flexible it is, and good it sounds, I think this is one of the best values on the market for sonic adventurers. You owe it to yourself to check it out.
