I have an acoustic guitar which has a built-in preamp and is suited to be directly plugged in into an acoustic amplifier - for which I do not know whether it has an additional preamp or not. Side question: Do acoustic amplifiers usually have one, respectively do acoustic amplifiers work with both active and passive pickups?
For my electric guitar I am planning to buy a new amp. In contrast to my acoustic guitar, the electric one has passive pickups. My questions now is basically the same as for the acoustic amp, namely whether a normal amp like e.g. the Engl e315 expects a pre-amplified signal or not. Until now I never thought about it and was sure that it is supposed to work with passive pickups, but I got confused along the way since the amp head itself also has a built-in preamp and the internet states that passive electric guitars need an external preamp.
However, normal amps should also work with guitars having active preamps?
