I must confess that I often play on passive bass, mostly Fender Precision or Jazz Bass, but I have a few pre-amped bass guitars in my collection, which I tend to use less because the sound tended to crash in the middle of a gig, as if the battery failed to support the preamp.

With the ZAM, this problem vanishes. On the contrary, the dynamics reappear, the low notes are deep, the high notes sharp and I don't have to bother with battery.

I have already ZAMed a Fender Jaguar, a Sandberg California PM44 and a Did Tribute P51-5 and I'm about to ZAM my two Musicman Stingray and my Takamine B10.
