Customer reviews consistently say that this amp represents great value for money. Most reviewers were quite happy with the clarity of the sound it outputs.


A small number of reviewers said that it distorts when turned up to maximum volume, however others said the opposite - this issue may be dependent on the strength of the input signal. One person pointed out that you don't get great volume for instruments with passive pickups.


The vast majority of reviewers are happy with this amp and the added flexibility of being able to add a subwoofer is a feature that has been well received.
