Toddy54 Posted March 27, 2010 Share Posted March 27, 2010 Can any one please help, have a Carlsbro 150watt 4x10 combo, but the eq only works on the first 5 sliders (bass end ) the others make no differance at all. Have tried cleaning them and even tried a bit of switch cleaner, but nothing seems to work. My mate has put a meter across them and he says there is no reason they don't work. Any ideas please.

jonny-lad Posted March 27, 2010 Share Posted March 27, 2010 If the combo has a tweeter, it might be a problem with that - if the tweeter isn't working, the higher frequencies that it covers won't be produced and the sliders that control those frequencies will appear not to work. Not sure what the problem could be though, as I've never had a problem with this kind of thing myself (but then I don't use much treble in my own tone), but from what I've heard online from other people's experiences, it could be that the tweeter has blown, the little bulb that protects it has blown, or there is a problem with the crossover. Hope this helps! Quote Link to comment Share on other sites More sharing options...
Toddy54 Posted March 27, 2010 Author Share Posted March 27, 2010 Many thanks for the reply Jonny-lad, what you are saying makes sense, I will have to look to see if I can see anything. Have been looking at the sliders and as you say it could be somthing connected with them ( I am rubbish with electric's ). Quote Link to comment Share on other sites More sharing options...
hillbilly deluxe Posted March 29, 2010 Share Posted March 29, 2010 The graphic eq sliders,obviously,are tone controls,they will affect the sound wether there is a tweeter in the cab,or not. One of the sliders in my Carlsboro head took a knock,and now does'nt work,testing it on a meter says it's fine,but it is'nt.The slider needs to be repaired ? or replaced.

Toddy54 Posted March 29, 2010 Author Share Posted March 29, 2010 I will have to a word with a chap I know he is a tv audio repairer, and see if he can get any replacement sliders. With Carlsbro no longer in business and the amp being about 25years old Carlsbro spares will be very short on the ground. Thanks for the reply Hillbilly deluxe.
