    Does anyone know where i can view / find a schematic for the pups/electronics on this bass? Preferably a color diag, but anything would help
    This is the 1982 model, MBll pickups, stacked knobs, coil taps, open book headstock

    I've had no luck so far.

    The Aria Pro IIs with the preamp are the most complex and hard to repair, so good luck. I could find diagrams for the SB-1000, but none for the SB-900, although they're supposed to be similar. Is this one of the models with the preamp, rotary tone switch and active/passive switching?

    If the bass is passive (no preamp) then any 'standard' passive wiring scheme will work.

    Yup, its a passive dual pickup job, so , different to the 1000
    Might have to wheel it over to my local git tech. Shame that website has no diagrams

    Late response, but should be identical to this

    Thanks , and i guess it's similar. There are 2 seperate switches , both 2 position, for series / parallel on either pickup.
    In the end, it turned out both original pickups had lost all top end , and it was very noticeable. The bottom was ok, but there almost no top end. Even the series parallel switches only worked in series.

    I turned to Kent Armstrong's son Aaron, who i guess everyone here knows lives in the UK, and he built a pair of custom pickups to match the sound and shape of the Aria original MBll's
    I wired them back in and everything came back.
    Awesome tone, and its my main gigging bass

    Wow that looks absolutely gorgeous! The white pickups matches surprisingly well - really cool.
    I had the same problem with my '81 SB900. Ended up swapping the original pickups for a pair of Rautia MB-II pickups ( and I couldn't be happier. Like you, it's my main axe.

    Likewise - good looking bass, pal.

    Yes, i tried Rautia and had an email conversation with him, asking about using a company called TransferWise to exchange my £GBP , rather than his request to use Paypal. The exchange rate Paypal give is pretty much the same as my bank, which is daylight robbery, so hence me asking to use TransferWise.

    I've used them before when i bought a Carvin amp from Germany, around £500 maybe $750. I paid about £2.50 maybe $4 for the exchange via Transferwise. Paypal and my bank wanted around £30

    But Rautia wouldnt play ball, so i declined to buy from him and went to Aaron instead. He did a great job and i had the pickups a week later. Rautia quoted me 4 - 6 weeks
