Earthquaker Devices HoofReaper Help

[USN_Ag06]

I just got my new HoofReaper Fuzz delivered on Friday, mainly for the Octave and Hoof, but I wanted to play with the Reaper fuzz as well. I can't. The reaper produces a terrible feedback when switch on and I can't figure out why. I tried switching it on with no guitar plugged in and it produces a loud static in all knob positions except for 0 on level that the Hoof side of the house doesn't. I thought maybe it was the amp, so I tried unplugging my board from my Bugera 1960i, and plugged into my Egnater Rebel 20, same results. I tried isolating each pedal in the chain, and it's definitely the Reaper. I tried changing out the cables and replacing them with male/male pedal couplers, I even bought a new power supply today (it was plugged in to a Dunlop power brick, now I also own a VooDoo Labs Iso 5). I can't for the life of me get rid of the squeal when I engage it. Does anybody have any tricks for this?

My signal chain is as follows

Front of amp:

Guitar -> Jim Dunlop Wah -> TC Electronic Polytune -> Maxon OD808 -> Boss DS-1 -> Earthquaker Devices HoofReaper-> Bugera 1960 Infinium Front of Amp

FX Loop

Send ->Electro Harmonix Nano Holy Grail -> TC Electronic Flashback Delay -> Return

The Reaper side (tonebender circuit) may need to see direct input from your guitar. I'm not sure on that but try it. Many vintage fuzz circuits react poorly or oscillate with other pedals and especially buffers in front.
