Pros

A common comment in positive reviews is that this amp sounds clean and crisp, and has good enough volume to satisfy many reviewers. With its three channel design and multiple input/output options, many users consider this to be a great value amplifier.

Cons

A small number of people complained that it wasn't loud enough for them but they were part of a small minority of customer reviews. Note the the XLR mic input doesn't have phantom power so you can't use most condenser mics with it, but that's not too much of an issue because most singers use dynamic mics on stage.

Overall

If you need to sing through your amp, as well as putting your instruments through it, then this is a good budget personal PA and Keyboard Amp combination.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Keyboard Amps.
