This is one of those amps that you wish they would have never stopped making. This is the QC 412 which is a stallar bass amp for combo players and smaller gigs. This is this the kind of amp that makes you want to join a band and rock out. If you are a bass player and you have never heard of Huges and Kettenr than there is a reason for that.

Hughes and Kettner have never really branched out in the bass world as far as getting bass guys to join there squad. They have really set their attention and sights on the guitars players. They have some famous guys such as Tommy Thayer and Alex Lifeson who have signature guitar amps from Hughes and Kettner but you don't hear to much about the bass world. That is a shame because their bass stuff is very good.

This amp has the same extra features as the 412 but just with an extra speaker. You get twice the air push bu the exact same voicing and feel. This amp has a nice DuraDome Neodymium speaker inside. The tone is nice and punchy and gets gnarly growl tone that is suitable for crunch tones in your music. The tone is a great bass tone. You have a saturation overdrive control knob that allows you to drive your tone even more than simple bass clean tone. The amp also has a great serial effects loop for allowing you to incorporate your favorite effects pedals or rack units into your sound. This is one fine bass amp and very versatile amp as well. It also has a balanced line out for going straight into a house pa system or mixer or even going direct when in a recording session.


These amps have been discontinued for some time now. These amps vary between wattage and speaker size. I have no idea what these are going for on the used market I have seen the 310 version for around $300 so I can only assume that this one would fetch a little more than that. It is a great amp for those needing a good practice bass amp or a convenient combo to go direct with. If you can score one of these on the used market for a decent rice for around $300 it is worth the purchase.
