shybaldbuddhist Posted November 29, 2013 Share Posted November 29, 2013 Hi all, I've had the BH500 for a week or so now and I love it, the sound is great and it's really versatile. One problem I've been having though is with the treble and tweeter controls. They don't seem to make much different to the sound when I turn them. Anyone else found this? I'm aware that the treble control boosts and cuts at different frequencies but it still doesn't make any difference. I'm using it with an Ashdown mag 210 deep cab. Could the treble control be broken?

JapanAxe Posted November 29, 2013 Share Posted November 29, 2013 If your cab is working right, it will give you up to 20kHz thanks to the tweeter. Without the tweeter it would only give you up to about 4kHz. According to TC's tech specs, the BH500's treble control operates to cut at 1.6kHz and boost at 4kHz. It doesn't say what the tweetertone does, but presumably it is meant to operate on higher frequencies. All this makes me wonder how much top end is coming out of your bass in the first place. What bass are you playing, is it active or passive, what strings are on it, and how new are they? Quote Link to comment Share on other sites More sharing options...
shybaldbuddhist Posted November 29, 2013 Author Share Posted November 29, 2013 I'm playing a MIM Jazz Bass and i've just put new Rotosound strings on it so it's pretty zingy! I can hear a really slight difference with the treble control but nothing with the tweetertone. I'm thinking it might be the cab... Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted November 29, 2013 Share Posted November 29, 2013 Plug an iPod or something into the Aux Input and play something with lots of cymbals in it. This should bypass all the tone controls. Get your ear down by the tweeter (careful with the volume!) and listen. You should hear a difference when you put your hand over the tweeter - if not, your tweeter is dead. If all is good, try playing your bass with a plectrum, and all controls on the guitar full up. Compare between full treble boost and full treble cut on the amp. I bet you can hear a difference now!

shybaldbuddhist Posted November 29, 2013 Author Share Posted November 29, 2013 The Aux Input only comes out through the Phones out but i ran my ipod through the main input with the EQ flat and it seems that the tweeter is dead. When I adjust the treble and tweeter controls while playing my ipod you can really hear the difference through the main speakers, much more than when playing bass through it. I guess this is because the bass isn't making as much noise at the higher frequencies. New tweeter it is then! Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted November 29, 2013 Share Posted November 29, 2013 Didn't know that about the Aux In and phones out on the BH500. You're right about the treble content of recorded music compared to a bass guitar. Did you do the thing where you cover the tweeter and listen for the difference?

shybaldbuddhist Posted November 29, 2013 Author Share Posted November 29, 2013 The Aux only coming out of the Phones out is a bit annoying really but i have another amp that does this so it's not too much of a problem. Yes i covered the tweeter and there was no difference. I also put my ear right up against the grille in front of the tweeter and couldn't hear anything. Must be blown. Any ideas where to get a new one? Quote Link to comment Share on other sites More sharing options...
JapanAxe Posted November 29, 2013 Share Posted November 29, 2013 (edited) Suggest you contact Ashdown via their website. I did this before when I had to replace a 15in driver and they were very quick and not too expensive.
