liffordmark Posted November 9, 2015 Share Posted November 9, 2015 I bought a TC Electronic 750 amp and a 112 cabinet and I am getting a distorted sound from E and B strings even at low volume, I have checked frequencies and gain set to right level and have used different cables, I have also changed the battery on my active bass. I have also tried 2 other 4ohm cabinets with the amp a ebs 410 and a EBS 210 and the same problem occurs and on these cabs the vibration/noise is coming from output panel on back of cabinet and there seems to be air coming out of Jack outputs. Any ideas lads and ladies as the amp has a killer tone but this is doing my head in. I've also tried my 4 string with it and the same problems occur Quote Link to comment Share on other sites More sharing options...

jonsmith Posted November 9, 2015 Share Posted November 9, 2015 You say that the problem occurs when you use other cabs, yet seems to be coming from the cabs mechanically rather than directly from the signal from the amp. Would seem very odd that three different cabs would all exhibit the same fault with a clean signal. What does it sound like through headphones?

liffordmark Posted November 9, 2015 Author Share Posted November 9, 2015 Sounds crystal clear through the headphones out in back of amp Quote Link to comment Share on other sites More sharing options...
Muppet Posted November 9, 2015 Share Posted November 9, 2015 Have you swapped the speakon cable for a different one? Quote Link to comment Share on other sites More sharing options...
Mudpup Posted November 9, 2015 Share Posted November 9, 2015 Yup, as above - a dodgy cable sounds the most likely culprit Quote Link to comment Share on other sites More sharing options...
