Hmm. I think I might have a blown tweeter in my CMD121P combo -- which I bought used, so, as far as I know, no warranty for me. The reason I say "I think" about the tweeter is that, 6 or 8 months ago, it did the following:
paper-y, fluttering sound (as if there were a small piece of paper held against the woofer, but definitely coming from the region of the little tweeter)
followed by...
loss of high end; everything sounding muted and muddy.
It did that for a day or two, then stopped -- everything went back to normal. I don't know if something re-aligned itself in the tweeter or what, but that's what happened.
A day or two ago, the paper-y fluttering started again. Today, playing my fretless, the loss of high end. This is at very low volume, btw. The amp is not being pushed at all.
When I contacted Markbass directly by email, the first time, I was told that they don't send parts -- any parts -- to consumers, and that the only option would be to send the amp to an authorized service center for repair -- i.e., shipping both ways, plus parts and labor. If that's changed, great. Please let me know, via PM if you like, what I need to do to get a replacement tweeter and what it'll cost.
If, on top of that, the Markbass techs would be willing to answer some questions, then that would be over-the-top great.
I can probably find a compatible tweet elsewhere, but if I can get it from Markbass at a reasonable cost, cool. I haven't opened up my amp yet, but, as I am out of warranty, figure I haven't got a lot to lose.
If Markbass can provide replacement parts and/or specs, that'll go some way to improving my impression of their customer service.
If there is a service center that I'm confident would handle repairs reliably, quickly, and at reasonable rates (should I ever need it for this or my Markbass SD800), that'd go further.
Your taking the time to answer questions of this nature on here, Peter, does shed a positive light on the company.
