I recently found out my father, who uses speakers in engineering, could get Celestions at trade price. So I though I would try a G10 Vintage in my Vox ADVT30.
First impression - a real difference - a definate change, and certainly for the better - the notes have more definition and the 'attenuator' (I doubt it is actually an attenuator) actually seems to pump out good stuff at lower volumes, unlike being a mud contol (which it was before).
Even with 3 watts setting from the 'attenuator' its louder and clearer.
On the bad side - the FX seem to have been tuned to the original speaker and now i can tell they are cr@ppy digital effects.
The sound of the guitar is now different - more defined but different: so I will have to get used to it again.
Cant wait till the speaker wears in - it sounds tight at the moment, so I hope it opens up over the next couple of weeks.
Slight ghost rattle - I think I didn't screw the speaker in tight enough - i'll see if it corrects itself.
