I first heard about and tried a Source Audio product a couple years back - the SoundBlox 2 Dimension Reverb. For the price and footprint, I was overly impressed with the sounds it could produce. It was extremely editable - you could affect pre-delay, have presets, EQ, and more.
One of their most recent products, the Nemesis Delay, partnered with their Neuro app for iOS, is flipping the effects world upside down. I've never seen or played anything like it! You can save so many presets, attach external auxiliary switches for easy preset switching, control editables like mad in the Neuro app, and get those unbelievably whacky or classic delay sounds you're looking for.
Go sell your $500 delay unit and get this thing. You'll never look back. Check out the video below for more info on the Nemesis delay unit.
I can't say enough good things about the sonic quality, build strength, and amazing artist support I have encountered so far with Source Audio. Play their products. Buy their products. I love my Source Audio Nemesis!
