Peavey KB 1 20W 2-Channel Keyboard Amp


This is Peavey's entry level keyboard amp which can also be used for electronic drums, drum machines and backing machines.

Peavey build tough to withstand the rigors of regular transport and gigging - our editor used a Peavey keyboard amp for a couple of years and can personally attest to their build quality.

It's very well regarded as a practice amp or as a stage monitor - if that's what you need and you want Peavey ruggedness then it's a good low cost option for you.
