I get piezzos from Maplins, usually the YU87U. However, I'm beginning to think that there may be variation in the way they behave due to manufacturing inconsistencies. Anybody else think they vary quite widely? And I think these behaviours are not just due to the fact that each cbg is different. Okay, I know we can't expect much as they cost less than a quid, but I'm curious to hear other people's views. Cheers.

Physics lesson coming up - might help understand a bit. The discs are primarily designed as buzzers, they just happen to work microphonically as well. So I think the resonant frequency quoted is the one that it will 'buzz' or oscillate at when used that way. Using it as a mic is like putting it in reverse but the tonality will be more down to the construction/materials of the box but the piezo type may have a slight bearing.
Having messed about a bit with my graphic EQ to control feedback, I was surprised that the main frequencies of feedback were around the low end 300-500 Hz. That's the frequency that my guitar boxes are resonating at which is not the same as the one stated on the piezo when used as a buzzer. The normal audio range for humans is about 20-18000 Hz at best but from an instrument it is much lower. Top end more like about 6000Hz. So what I'm saying is there are various factors involved. In short though I have noticed different tonalities but not made a note of what type of disc was used. Probably is some slight difference but the individual resonances of the guitars and boxes make it hard to determine.
