hi everyone,the guitar plug/jack on my old fender jass bass guitar is for 1/4 in FEmale plug, but during gigs I encountered venue using the XLR male plug which is not compatible with a 1/4 in female plug. We try to connect it using an adaptor ( XLR female to 1/4 in male plug connector, with the 1/4 in male plug will be connected to my bass guitar while the XLR female will be connected to the XLR male which is then connector the venue sound mixer/console or whatsoever,but the results has no sound. Can anyone help me on this? I plan to buy one adaptor for this purpose but I am afraid that it will be useless. When we try to practice in our home and we are using the 1/4 male plug and connect it to an amp and the sound is good. But during gigs,with some venues using XLR, it wont sound at all. Our first gig using that bass guitar end up almost a disaster. Thank you so much in advance for anyone who would try to help me on this. Here are the countermeasures that we applied but fails: 1. Possible cause #1: The volume knob on bass guitar is very low, we try to volume up but still no sound. 2. Possible cause #2: The cable is defective, but we try to use different bass guitar not mine but it sound. 3. Possible cause #3: My bass guitar is defective, although I am not sure on this, but we try to change cable lines instead of using that cable, we use the cable for the vocals microphone, and it sounded..although after couple of minutes there was a strong feedback and it resulted on no sound at all. Although i am not sure if the venue turn that off because it is for vocals. 4. Possible cause #4: The controlling mixer volume for the bass guitar is very low, but it is set near to max volume and other bass guitars except myself will sound.
