Installed the new preamp this morning. Instant fix. The guitar sounds amazing. The cleans are lovely and full, but it gets to breakup very quickly. Probably a combination a Marshall DSL 20 head and the 10 inch speakers from a mini stack and the very hot pick ups. Full gain causes the speakers to collapse. Will try a cleaner amp with more head room this evening. Will also look for some original power plus pickups online. Many thanks to Prostheta!

What’s the best way to acquire one, still ebay?

Thanks Prostheta. Updates on here would be perfectly fine. I’ll check back here periodically.

Fantastic. Thanks for the quick reply. I have sent Prostheta a message via ebay.

Aria pro ii BB noise killer circuit. Apologies for bringing a guitar into a bass forum. I have acquired an 1979 Aria Pro ii nk-700 which has the same noise killer circuit as in the later SB-1000 bass guitar. When the volume is very low it sounds awesome and full. But anything above 1 (on a scale of 1-10) becomes almost white noise. I have replaced the batteries in the circuit. The pickups are not the original power plus, but a PJ Marx in the bridge and some kind of super distortion in the neck. Probably changed some time in the early 80s. Weirdly they are both reading about 18 ohms when I measure them which doesn’t seem right. (They are crazy hot 80s pickups, but not that hot). Although the pickups have been replaced, it doesn’t look, to my casual eye, as if anyone has messed around with the rest of the circuitry. There is a black box in the middle of it all and I read on an old thread on this forum that this component can die, leading to this white noise and needs to replaced. I also read that there was a gentleman who made replacement black boxes and sold them on ebay, but the link had expired. Any help on this would be much appreciated. It is an amazing old guitar. many thanks, Ian
