That pedal you have is a more agressively voiced version of the "Blue Tube" pedal which I own. A friend of mine had the Real Tube and I played along with them side by side.
IIRC the Real Tube was a bit higher voiced than the Blue Tube.
OK - reality is, even my Blue Tube robs some lows. Effects loop won't help unless you have a blend. That would help your situation - a blender pedal. That allows you to blend in your dry unaffected signal - which is why so many people here use one. Helps you maintain the lows that many effects kill.
IMO, the english muff'n isn't the answer. (No Offense) I had one and it didn't work for me at all. Blue Tube sounds way better for my setup, much lower voice. It has a built-in eq just like your Real Tube, but as you've already discovered the punch and lows from your normal sound is still missing, even if you dial up the low in the eq.
Blender is the solution for that problem.
