Having some weird issues with my MAZ 38. Recently I has started making some really funny "tones" when certain notes are hit on the fret board. The best way I can describe it is almost an echo of the original note with more bass added to it. I'm thinking it may be time to change tubes again. This thing loves its tubes!!!!! Any ideas? Would all the tubes need to be changed or just certain positions? Anyone run into this type of microphonic issue with their MAZ? Ideas and thoughts appreciated.
If I understand correctly, I think what you are hearing are ghost notes. (I think that's what they are known as anyway). Some amp designs do it more than others. I remember a thread a few years ago which talked about the same issue with the Route 66. Anyway, my Maz Sr does it, and it's mainly more noticeable when playing double stops, with some amp breakup happening. Also, I notice it more through my Celestion Gold than I did with the Vintage 30 I used to use. That figures as the Gold has more bass, and is a bit looser than the V30. It doesn't happen all over the fretboard, just in certain positions. To be honest I've never worried about it, just accepted it as part of the amp's character. Mine is 10 years old now, but it's always done it, even when it was fairly new. I don't think it's a fault, and it's never gone away when I've changed tubes, and actually I quite like it. I do think that if you try to get rid of every little idiosyncracy you can end up with a sterile sounding amp, so I've left it as it is. My apologies if you are hearing something different!
How long ago did you change tubes? I was getting a little frustrated with my 38 not too long ago. Even after replacing the power tubes I was still having some interference and white noise occurrences. It wasn't until I changed out the preamp tubes, PI, and rectifier that it went away and gave it new life.
