Dear Sandy,
Aria Sinsonido
Just found your circuit board notes re above bass and would welcome your comments on following since my understanding of electrics is just above zero!
I have a fretless early version Sinsonido bought new many years ago and all working fine - which I fitted with Thomastik - Ingfeld phosphor bronze strings - the ones developed for Rick Turners range of Renaissance basses. The aria is my go to fretless on lots of gigs.
I've been keeping an eye out for a spare at a sane price and one has just arrived. It appears to be a later model without the headphone output ( which I never use anyway ) and the two controls on the bottom of the body not the top. It all works (tone ok, balance across strings ok) except the output is probably a third of the volume to my "old" Sinsonido and not sufficient to gig.
Pots both work, jack cleaned with alcohol but not sufficient output ....
Indications are the "gain" element of the circuit is duff and any pointers from you to resolve will be much appreciated.

hi Patrick
thank you for kind words. my advice is to stick resolutely to 65, when reached.
7 years on , and i've never seen the insides of a hospital so often!
i can't comment on the serial numbering issue (Aria helpfully don't provide a lookup service AFAIK)
There are a few members here with different versions of the Sinsonido and it is evident that the design has evolved over the few years of production
Version is important because Aria completely rejigged the PCB electronics layout when evolving to the version with controls on top of body, plus having a mini headphone jack and DC power socket on the underneath.
The PCB circuit was also changed, adding an extra IC (to drive the external phones jack?) and removing the Controls into a separate cavity
The final evolution appears to offer a stacked Bass&Treble control in place of the single Tone control (with controls on top}
@Lemmywinks has posted a photo-compilation of most versions (in approx reverse order of appearance}
He has one of the early versions with straight sided body with controls below
i have the next gen which keeps the controls below but widens the body around the control area
On these versions a stereo headphone signal is provided on the main instrument Output jack (ie. disconnecting the cable to the Amp and connecting headphones instead)
my JFET PCB is designed as a replacement for the versions with controls below, and wouldn't be suitable for the 'controls on top' versions
i'll try to get another PCB milled asap in the New Year
regards
sandy

Dear Sandy
Thanks
I attach photos of the low output bass which is definitely poorly - I think your JFET PCB is what is required !
Off to gig the double bass tomorrow which, in stark contrast to the Sinsonido, is a very physical challenge! My first Sinsonido will be on hand as an emergency backup.

Hi Patrick
Thanks for photos
yes, this is one of the versions for which my PCB is designed
I empathise about the physical challenge. I was glad to find and use a Sinsonido (then fretted), instead of my heavier & larger-bodied basses whilst my Blues Rock continued. A small offset to the weight and hassle of transporting, loading setup of my bass gear and all the PA
Since playing the Sinso (now fretless, and used as EUB) with more acoustic-oriented line-ups, it's been a real joy to use with only minimal gear
