There's likely a reason why the OCD is the most suggested pedal for Orange amps, I just didn't happen to find any used here in Italy so I guess I'll save it for another time lol. Never considered the SD 805 OD, it's not something you see that often on pedalboards, how's it? I have space to fill in my board atm.
I might as well consider a low cutting OD in place of a EQ (I've have bad luck with EQs in the past when put in in front of amps, very annoying hiss and not very natural sounding units. Maybe things got better in recent years with mxr or boss), like a boss SD-1, I just don't like what the SD-1 (which is better than TS9 IME) does to treble, it gets fakey. I heard the Waza fixed this a lil, not sure.
