Thread: SR4 active electronics not working

    Angry SR4 active electronics not working

    Hi

    I've tried a few batteries and it seems my active electronics are not working as i cant get any tone out of it. It's working without a battery. Volume is fine but absolutely no tone. Time to take it to the repair guy?

    Is this common?

    It was a brand new 2011 model i think. E

    Just to clarify: Are you saying that the bass outputs a powerful enough signal, and the volume knob works as expected, but there's no change to the sound when you twist the EQ knobs?

    Does the bass behave the same without a battery as with a battery? Or is there a difference?

    id suggest making sure the metal pieces that are supposed to make contact with the poles on the battery are actually making contact. sometimes these can be bent so they dont make contact. bending them back a little bit usually helps

    if this doesnt work i suggest contacting eb customer service. internet diagnostics is a hard task to do and you will get very good help from the ones that knows most about eb basses

    less relief / flatter = lower action
    more relief / bow = higher action
    do NOT use cheap tools to adjust with. they break and scrape up your bass!

    if you have a 100th namm sr4: the truss works the other way around on those!

    i have no affiliation with eb other than i love their basses

    yes it behaves the same. it's as if there were no electronics at all. tried with a brand new battery.

    ^^^^This and also check to make sure you install the battery correctly with the + and - the proper way. If not, then contact customer service.

    yeah thats what i thought too although i never got around to checking that when it was behaving ok. granted the signal seems weaker but it's strong enough that i dont have to move my gain on my amp. weird

    found the problem. i took the battery housing out and the wiring has come away from the housing. both sides. pretty disappointed as it's a lousy soldering job and this bass has never been bashed around. from what i can see, when you open the carrier, the wires have an excessive amount of movement and eventually they will just give way. taking it back to the shop.

    so i guess thats why i have signal thru as the pickup becomes totally passive when these wires arent connected to the battery carrier.

    While reading this post I was really surprised to see you write this, my new SR4 HH has tons of volume without the battery in. It has no tone control at all but there is a lot of tone change with the selector switch, which I assume it would because of the all the different pup configurations when using the selector. Definitely enough volume to get you though a gig in a pinch...

    Must be differences over time. A while back someone wanted to
    know how to check out the passive tone before doing any mods.
    Before putting-foot-in-mouth and suggesting to "just remove the
    battery" I figgered I'd better test that idea. On my own ax I got
    no useful signal.

    Sorry I can't helpfully say which model, as I've got more than a
    few [see sig] and I only tested one, believing that all models will
    have the same result. Now, you've got me curious !

    Is it the soldering that has come loose? Did you buy it new? How far do you open the battery compartment?

    Try the store, or EBMM customer service, the best in the business!
    bovinehost: Yes, I do agree with that, but if there's nothing wrong then there's nothing wrong.
    Beth: I would compare Bongo to Tommy Lee Jones. Bad a$$ and just hot in a weird way...
    cheezewiz: They should take their lace thongs off and play bass.

    Great find, I guess we now have something to back the thought of passive/no battery play that we can all hear. I had recorded some stuff last night without the battery but could`t figure out how to post it. Wanted Golem/others to here the tone and how easily it was heard in a live situation. Was wondering if mine was the fluke ? Guess not, cool

    Yeah the soldering came completely apart. note to self: dont open it up all the way. this was mainly due to the wiring catching on the body. i showed it to the repair guy and he is going to give it some more slack.
