What you're saying makes sense to me! I will not be going back there 🤦‍♂️

Thanks for the replies. The tech tried around 3 different barrel jacks, only the last of which has the 4 lugs which is what is currently installed. I just can't understand how he would have wired each one of them up incorrectly every time! I'm sure he told me he had reversed the wiring at one point, just to try and see if that fixed it - which it didn't.

I've taken some pics, sorry they aren't very clear. The light brown bass is the 4-string with the original Ibanez jack. The dark brown bass is the 5-string with the newly replaced jack. @tauzero, I haven't unfortunately as I don't have a multimeter. If I take it to someone else, I will show them your suggestion.

Near Southampton. I'm a bit reluctant to have a third tech look through it as I'm worried about wire fatigue and spare parts. Finding this bass was like a needle in a haystack and there are no spare parts available for it if something were to break 😔

Ah, understood! I just found it strange that there was absolutely no buzzing or low battery indication the previous day, and then it was completely dead the next. I have also been turning the volume on the bass to zero after unplugging the jack, just for good measure. But it hasn't seemed to have made any difference

Sure, I will take a pic soon. I don't understand your second comment - prior to the jack replacement, the 9v would last months and months. In fact, I don't recall ever changing it in my 3 years of ownership. I also have the exact same bass in 4-string variant, similarly, I have never changed the battery in that either. I will take a pic of the wiring for comparison.

Update - took it to another tech, they couldn't figure out the problem either. It just seems to be random... For example, the battery can last fine for two weeks, and then I will play it on day 15 and it'll be completely dead, and I mean completely. But there would be no buzzing or any kind of indication of a dying battery on day 14. Of course I now really wish I never had the original jack replaced for what was in hindsight a very minor issue!

Yep that was the first thing be assumed, though he was certain it was wired up the same as the previous jack. Regardless he re-wired it again but opposite, and the problem persisted. Hence we're both now stumped!

Hi all, wondering if someone could help me with a problem. I gave my Ibanez ATK805 to my tech a couple of months ago to replace the original 1/4" jack, as it had become a little loose (audio signal would cut out if the cable was twisted in a certain way). Within a couple days, he replaced the jack without any issues. I used the bass at a couple of rehearsals and everything seemed fine. A couple weeks later, I took the bass out for band practice only to find the 9v battery was completely dead. Thought it a bit strange as in 10 years of playing, I've only replaced the 9v once or twice on any of my basses. No matter, battery replaced and all working again. However, I took it out again for another rehearsal the following week, and the battery was dead/dying again. All farty. Replaced it with my last spare 9v and all was fine again. Took the bass back to the tech and explained the problem. He's since replaced the jack a further two times, with two different jacks, and the battery drain issue still persists. He cannot think of anything else that can be causing it, and is certain its all wired up correctly... Can anyone think of anything that might have been missed?

Hi all, I am currently experiencing a very annoying problem with my Ibanez ATK805. It was previously working perfectly fine, the 9v battery would last for months. I always carry a spare battery in my gig bag, but don't recall having to ever actually change it, ever. The input jack had a slight loose connection in it - the signal would cut out if the 1/4" cable was pushed in a particular angle. So, I took it to my local guitar repair tech to replace the jack. Now, the jack problem is fixed but the 9v battery drains extremely fast. But it seems to be random. At one time a brand new battery will last a couple weeks, and then I'd take it out of my gig bag and it would be dying. Though another time, I'd put in a brand new battery and it would be completely dead two days later... It's been back to the guitar tech twice now to try and diagnose the problem, but he can't replicate the issue and doesn't know what's wrong with it. So, I thought I'd post on here to see if anyone has any suggestions! Thanks all

Haha fair enough, I love opening up all my amps and seeing how they all differ
