Description & Condition
Description & Condition
In recent years, the company has gained worldwide popularity and is trusted by many professional bass players at the forefront of their field.
This product is a 900W monster amp based on their masterpiece Microtubes B7K, built in full analogue.
It features a 4-band parametric equaliser with BASS, LOW MIDS, HI MIDS and TREBLE, while the two MIDS controls can be switched between frequency bands. Separate from this clean section is a Microtubes section with a drive sound. This section covers everything from tube-like warm sounds to violent, ground-crunching distortion sounds. The on/off of this section can be controlled by a footswitch, so it can be used like a single drive pedal.
The basic sound is clear and the response is quick. This is a common element of the D-class lightweight amps that are so popular these days. The Microtubes section allows this sound to be moderately dispersed to give a roar as if you were driving a large stack amp.
The size is very compact at 26.7*23*6.4 (cm). It weighs only 2.9 kg.
The manufacturer has achieved great success in the field of effectors and has released a product that lives up to expectations when it comes to head amps.
Scratches and dirt are scattered throughout. Operation is good.
