Hevos 400D hybrid bass amp. High end tube pre amp (front), 400W class-d power amp (center), extreme stable power supply ( top right and left).
German magazine Gitarre&Bass wrote: “Beyond all doubt is the flawless and transparant sound of studio quality delivered by the hybrid amplifier, even at very high volumes. Moreover, the 400D manages to create this translucent and detailed sound reproduction by no means in a cool, but rather a well balanced warm way. These are real top qualities!“.
