    Comments about Dreadbox Erebus:

    Great little synth, makes a lot of really interesting and unique sounds, from the Mass Effect pings and bongs to some delightful pops and bubbles. Its just a lot of fun twisting knobs and finding a direction and seeing how far down that path you can go. Then when you start patching, its like, doubling sounds you're getting. Its not overwelming either as someone who didn't know anything about patching, you can play around and between the schematics in the manual and fiddling with knobs pretty much work out what things do.

    The people at Dreadbox seem like genuinely passionate people producing a great little boutique product. If you can get a Hades, you can chain it to the Erebus to add a really awesome evil bass line to the Erebus sound, and can patch between the two to take advantage of the features between the two.

    Can't wait to combine this with an Abyss, their poly synth in development to expand the sound possibilities even more.

    One thing to be mindful of, theres no presets, no memory, just knobs. You want a sound, you have to turn the knobs to get it, so either memorization or a lot of phone pics comprise your library. I personally find this as an asset as it means I'm constantly creating new sounds and tweaking old ones simply by recreating with an imperfect system (cant enter decimals and what not if you know what I mean.) This allows for "happy accidents."

    My chief complaint is the midi channel controls. You have to open up the box and switch around some tiny little jumpers to switch between midi channels omni-7. Its a pain in the butt, but once you get your rig set up, you shouldn't really need to change midi channels often. Seems like it could have been made a switch on the outside, even if it was on the bottom of the box (it sits on 1/4" high rubber feet so theres a bit of room, to even just switch between omni and the jumper set midi channel, because the synth is so versatile and I find myself wanting to experiment and use it in different ways.
