So I'm pretty new to the whole dabbing thing. I recently bought a Termini bub for concentrates. At first I had no problems with it... Until I broke the glass nail that came with it. I ended up buying a titanium nail and a taller dome to go with it. But ever since I started using this new dome and nail, my dabs have been smelling really bad, almost like a bitter kind of smell but I can still smell the pineyness from the oil. So I went and bought another glass nail and its still doing the same thing. It seems like its coming from the glass dome itself. Any ideas as to what's going on here??? I'm still using the same oil that I had before I broke my first nail, the one that I had no problems with.
