Hey Garfield,
this is my trusty Reverberation Machine ;) TC Electronic ARENA. I'm not using this for my Guitars too often but I enjoy the diffrent reverb types and colors for all other sound mangling. In the Patch I use the "Mod" color, where there is also some chorus/lfo modulation in the Reverb.
There is also a programmable Slot where you can create a Custom Reverberation Profile. I'm using one that can takes all the attack from your signal and you can build a fat drone from an electric bass for example.
Current diy-build status:
Muxlicer 80% done - but I'm waiting for a missing thonkiconn jack
Rampage 40% done - the mainboard is complete but now there is the control board on the list.
