Then, I learned the things about active basses (do not leave it plugged, in passive mode it also affects the battery) and the battery lasted like 8 months. And it wasn't my main bass at the time so I didn't use it that much. I'm curious if there is something wrong with my unit. Ah that's annoying! So if you remove the battery and switch to passive mode you don't get any output? Having said that, if you're not planning on making use of the active mode you might as well just get a 435...

I haven't seen a circuit diagram, but this doesn't sound completely right... Certainly my BB735A works as normal when I remove the battery (in passive mode of course). This would make me think that the battery is not in the passive circuit. 1 1 Quote Link to comment Share on other sites More sharing options...
jrixn1 Posted September 6, 2019 Share Posted September 6, 2019 Although I suppose the bass working in passive mode without a battery doesn't necessarily mean the battery isn't worn down anyway when you are in passive mode and have a battery in there...

This would make me think that the battery is not in the passive circuit. Yup, that would be my expectation from experience with all my other basses which have dual active / passive capability i.e operates just fine in passive without a battery present. @javi_bassist maybe worth re-checking exactly what is the position with yours and / or if you are saying something different to the point that John and I are getting at?

TRBboy Posted September 6, 2019 Share Posted September 6, 2019 Active basses usually use the input jack to activate the preamp (I. E. When the jack is plugged in, the battery circuit is made and the preamp activates), therefore whenever the cable is plugged in the battery will be draining, even in passive mode. At least you know passive mode works without a battery, so even if it does mid gig you can carry on playing in passive mode. Not all active preamps are like this, sometimes 'passive mode' isn't a true bypass of the preamp, and it won't work without a battery. 3 Quote Link to comment Share on other sites More sharing options...
javi_bassist Posted September 6, 2019 Share Posted September 6, 2019 Sorry, I explain myself really bad. I mean that, with a battery in it and in passive mode, I thought that the preamp wasn't using any battery power, and I was wrong. If I remove the battery, I can use it in passive mode without any problem. However, I prefer the active mode. But my concern is that it only lasts for about 8 months... Other players in my area with active basses (non Yamaha. They use Musicmans, Sadowsky, Sire...) claim that they don't change the battery in at least one year and a half or even two. That's why I think that my preamp might have something wrong Quote Link to comment Share on other sites More sharing options...

Comparing them isn’t all that useful. What batteries you using? 1 Quote Link to comment Share on other sites More sharing options...

Al Krow Posted September 6, 2019 Author Share Posted September 6, 2019 Ah, well spotted dB. Yup I think most of us leave our active basses unplugged when we're not playing them, and certainly over night, to maximise battery life. 1 Quote Link to comment Share on other sites More sharing options...

I think what he was getting at is he wasn't always unplugging it because he didn't realise, but even after he started unplugging it every time, he is only getting 8 months out of it.

whamni Posted September 7, 2019 Share Posted September 7, 2019 My 79' Musicman the batteries lasted years, the Sire 4 months, the Yamaha 734 since I started using Tesco own brand, they last forever, well a lot more than eight months.

dave_bass5 Posted September 7, 2019 Share Posted September 7, 2019 My Sire bass has the original batteries in it, and I got it when they first came out. I got in to the habit of always unplugging it when not actually playing it, even at gigs. As I use a wireless system it made it a bit easier as the lead would just hang from the strap.

Fair, you either love it or you don't! John is totally mad to be moving his 735A on anyway (I've already told him), particularly as he still loves it as a bass! Funnily enough I used to be a massive fan of 'burst. But I've now become an 'anything but' 'burst, overly civilised pups, 4 strings... 😀 1 Quote Link to comment Share on other sites More sharing options...
javi_bassist Posted September 9, 2019 Share Posted September 9, 2019 (edited) Update on my case: It's not that I always left it plugged. There were times when I took breaks and I left it plugged for one hour or two. But I'm doing another test so I'm being more careful now and I'm "counting" the days so I'll keep you posted haha.

Andyjr1515 Posted September 9, 2019 Share Posted September 9, 2019 Ref @Sibob 's woes on his trussrod maxing out, after a few PM discussions, he's sent it my way. I've just added it to this thread if anyone is interested 1 Quote Link to comment Share on other sites More sharing options...
Al Krow Posted September 9, 2019 Author Share Posted September 9, 2019 (edited) @Andyjr1515 - just quoting from part of your full post as there were a couple of "takeaways" that immediately jumped out at me, which I suspect may well be of interest to other folk, and which I've taken the liberty of highlighting. Have to say that in the over 2,500 posts we've had so far on this thread, I don't think anyone has made these points with such clarity - so thank you! 1 hour ago, Andyjr1515 said: While I'm waiting for the knobs to arrive for Tom's Squier, I've kicked off the initial work for another small job - this time for @Sibob Those of you who follow the Yamaha BB thread will know that he's had a problem with the neck on his BB415. Some kind soul suggested that I might be able to do something with it and so he sent the neck to me a week or so ago. Basically, @Sibob couldn't get enough adjustment on the trussrod to achieve a decent flatness of neck. I love Yamahas, but I'm not keen on the trussrods they tend to use. The love comes from the fact that ALL of their instruments are just, well, right. I play a Yamaha sax - and that is as good as every Yamaha guitar and bass I've ever played. Just look at the carve on this neck: It is as smooth as silk and it feels great! But - the trussrods are single acting and have a relatively small adjustment range. So they rely on the neck being flat with the trussrod loosened and no strings, then the adjustment is enough to counteract the bow resulting from the string tension. So - full loosened, it should be flat... Edited September 9, 2019 by Al Krow 2 Quote Link to comment Share on other sites More sharing options...
dave_bass5 Posted September 11, 2019 Share Posted September 11, 2019 Well ive given up with my P34. Love the tone, love the feel, but when i stand up to play it i find its awkward. Set up is fine for me, but i have a feeling its the depth of the neck. Tried all sorts of strap heights etc. it plays ok but i feel slower on it. I had a rehearsal last night and i kept fluffing the lines. Im going to go back to my Fender for now, or maybe give the 425 an outing. 1 Quote Link to comment Share on other sites More sharing options...

That's quite interesting, I've not played one of the newest series, but they've been touting them as having thinner necks than the previous series.
