The Peavey KB 3 is a kind of hybrid combo amplifier in that it can be many things to many people, essentially it was designed as a compact yet powerful keyboard amplifier but it offers a few other versatile features that make the KB 3 more than just a keyboard amp.
It has 3 seperate channels and a dedicated microphone input which means that this combo could also double as a small PA system, the power rating is 60 watts RMS which can increase to 80 watts with the addition of an extension cabinet. The KB3 utilises a single 12" speaker with a tweeter and each channel has 2 band EQ, there's also a fourth channel that doubles as a monitor output.
A handy inclusion is the FX send and return controls which effectively turn this combo into a compact and portable high quality PA system, there's also an XLR direct out just in case you have the luxury of connecting to an even larger PA rig.
