$275 Shipped!
Ok fellas, the little amp flat out rocks. Great tone and top notch german construction; I love this amp and have no issues with it. It is in like new condition, and is in a class of it's own. These things sold new between $715 and $950(street). This amp was made in Germany, and is nothing like their cheaper model.
I had this up for trade, but I just purchased a Markbass Little Mark III, so now it is for sale. I am also going to lower the price so I can recoupe some money I have on the mark III. Let's set the new price at $275 shipped!
The Hughes and Kettner QC 310 is a 250 watt bass amp combo with very flexible tonal control, tube growl knob and both passive and active inputs.
The four Quantum combo models’ identical preamp sections sport an array of impressive features. Fine-tuned for active and passive basses, the audiophile input stage with its vast gain range provides the underpinning for the amps’ tremendous performance power. Instant and musical tone-shaping control comes courtesy of the parallel four-band EQ section. With these no-nonsense tools, dialing in the sound you want is dead easy. Punch and HF Character switches are on board to enhance your sound-sculpting pleasure. And perhaps best of all, the nifty Tube Growl knob controls tube saturation level, compressing the signal and endowing it tube-driven punch and assertiveness. Quantum Combos are truly in a class of their own!
