First of all when the guitar is connected you have observed there is no sound or even any detection. the audio input comes up to the cord but when the jack is inserted the audio cuts off- or hums. If it hums you need to check the input terminals for loose connection.
Now the pick - ups and the preamp need to be checked separately.
Each of the pick coils must show a continuity, you need to use a multimeter in Ohms range to see the coils show continuity. The pick-ups are coils with magnets placed on the center which works on electromagnetic induction. These are wired through switches to the preamp. now check also the power to the preamp- check if there is a battery for the preamp. These preamp are basically op- amps with the impedance corrected for the input pick coils and a balanced output.
So a loss of signal here can be that the guitar is not responding. If you have a good guitar amp and pedal, then the preamp can be bi-passed.
Please check on these tips.
1.Plug another device into the input of your Amp,such as a mic or another guitar to ensure its not the amp causing the issue.
2.If you can hear sound from other device, make sure the input cable is good. (No cuts or rips)
3.You may need to take apart your guitar, The connections may be rusted is so all you need to do is use a wire brush to it just be careful.
4.if the issue is not in the connection itself you may want to replace the pickup on the guitar.
These are issues I have come across with my Jackson guitar, the connections were rusted however be sure to check the wire before taking out the pick up. Good luck
I dont' see where this model has active pickups (guessing this is what you mean by pre-ampped).
The issue can be in a few places.
1) the strings could be too far from the pickups and the instrument needs to be tuned.
2) the pickups are bad
3) your jack is bad
4) the cable is bad
5) your equilizers are not corrected
6) your volume control is turned down or damaged
7) your amp is damaged
this is a small list of the basic possibilities.
also check your amp settings. there are some amps that are retarded. lower the trebble, increase your mid and bass. if you have a cheap amp this can be the problem.
if you want to really verify that the guitar is outputting get a 1/4in to 1/8in convertor and plug this into your computer mic jack. get the program perfect pitch http://www.nch.com.au/tuner/index.html its free. this will allow you to even tune the guitar.
and so what of the items that i have given you as advice have you tried. No information is too basic unless you actually tried it. I gave you all the starting information in order to start diagnostic and all you give in return is "Too basic. Need other advice. " I also included alternative information to verify that your guitar has output but you did not even say you verified or have shown proof that you verified it has a correct output volume or sound.
oh and connecting it to another amp or computer will verify that the problem lies in the guitar and not the original amp.
you gave NOTHING of what you have done in order to fix the solution so i started with all the inital things to look at.
no its a magical flute. no duh its a four string bass with tone and volume control plus additional dual eq.
so your cable and amp are fine. what did you do to check the actual guitar. i'm using guitar as a generic term even though the electric bass is not a guitar....meh anyway i'm done with this another expert can have it. You don't eve inform us with the steps you have already taken or if you even tried "these very basic ideas". As basic as they are, unless you actually tried them you don't know what the hell your doing. If you did try them, i have already asked multiple times if you did and i guess you don't understand enough to answer a simple question. Good luck with the next expert...actually i wish them luck with you.
