[PD] mic preamp: hardware or inside Pd?

Thanks Pierre,
what i want to do is to get some noises through these coil mics and amplify some objects with piezo mics, no recording here, I mean will be also real time processing, just for jamming and get used to Pd. 
Eventually I will want to plug in a lap steel guitar or a 3 bridges guitar, it depend on if I can, finally manage to build one...
Could be nice a warm tube preamp sound, but for this, is not really needed.

> Now concerning the question of whether you should amplify the signal within Pd or not, i'd say it all depends on your needs. If you want to record a singer or an instrument it's always good to have an analog pre-amp before you feed the signal into Pd. If you need it for something else it may not be necessary.

Amplifying the sound in Pd will not change the sound, whereas amplifying it first with a pre-amp will change it (depending on whether it has tubes, and on the general quality of the product). You just have to choose what you like most.
