Ok - here goes with an update having used the Aria in all of my bands, country, rhythm and blues & jazz over the last few weeks.
The bass performs really well, the change of strings to helicore hybrids has definitely improved the tone. I still use the bass going through the EBS micro bass & EBS compressor & reverb units, (only a slight amount of reverb).
The tone is clearly not that of a double bass but i do not view that as a bad thing, the Aria has a sound of it's own, mellower and fuller than any of my electrics, precision, jazz & stingray. I think that those of us using these should not be defensive about it "not being a double bass". The instrument stands on it's own merits.
From the non musician audience the bass attracts a lot of attention as they are still quite rare to see in pubs, restaurants & functions. Most people who have spoken to me find the sound pleasing & the drummer from last nights gig commented that he felt there was more room in the songs, probably because i was conscious of not trying to play the same lines as i would have on the normal electrics.
My only problems with the Aria at this time is that i find the end pin not really long enough so i knocked up a little wodden block stand - approx 2 inches high - to make the playing position more comfortable whilst not having to extend the pin to it's absoloute maximum.
Also the volume control is quite noisy when being adjusted - does anyone else have experience of this & any solutions.
I do believe that we will see more EUB's being used in the future and that they will not be substitutes for acoustic double basses, the Aria has managed to perform very well in a variety of stiles. I'm sure that one day i will want to buy a more upmarket EUB, (suggestions welcome), but in the meantime i'm happy with what i have.
