my tube amp is getting warmer (less bright)...could this be a speaker or tube thing?

    Hi guys, I've had my Blackstar Ht-40 since Christmas and use it several times a week. I'm noticing that the amp sounds warmer (less bright) than before. It doesn't sound bad, just warmer. I'm needing to use more high's and less lows. Could this be a tube thing? Is the speaker breaking in? Thank you in advance.

    I'm hoping it's the speaker but new tubes are no biggie. I guess I should replace the power and preamp tubes at the same time?

    How about just compensating for it by using different tone settings ? Are you not able to get enough highs at this point at any settings ?

    What kind of tubes are you using ?

    Some current production power tubes will have their bias point drift after they break in.

    But if you can be happy as it is just with a different tone setting, I wouldn't worry about the fact that the knobs now need to be in a different place than before. That's normal, at least from a certain amount of speaker break in.

    I've got the tone knob on my Lester as bright as it will go and can compensate using amp EQ as you suggest. I'm just wondering what to attribute the warmth to.

    components breaking in, and your speaker.

    Have you tested this with gear that could help you quantify it definitively? Have you recorded it when you got it vs. now? It could just be relative/subjective. You might think you're hearing darker tones.

    It could by all means be that your ears and tonal tastes are changing. Might sound stupid, but I've come back to settings I used to use over the years. Playing them now, my reaction is akin to WTF! So, my ears and what I hear often changes with tastes.

    The other thing that is probably happening is speaker break-in.

    Both are breaking in....Tone is a goood thing! Consider changing tubes when there is noticeable volume or tonal loss...
