YAMAHA Bass Head Amplifier SR400B KORG Rack Tuner DTR-1000 Dupulex 4U Rack Case This is a set of the above 3 items. *Due to the weight, this is limited to direct transactions only. If you are in the Tokyo metropolitan area, we can deliver it for the highway toll + 1000 yen, so please consult with us. The amplifier is a YAMAHA masterpiece, solid-state, but because it is a vintage device, it has a huge transformer built-in, and it has overwhelming sound pressure and attack like a full tube amp, and it has a vast headroom that can withstand any high input even when using active bass or distortion effects at high gain. I have been using it as my main amp on gigs, but I am selling it this time because I own two. The power cable has been re-cabled once. A KORG rack tuner and a very sturdy Dupulex 4U rack case are also included. The rack tuner is designed to draw power from the back of the amplifier, so it is patched to operate everything with a single power outlet from the amplifier. *Please be sure to check. The cover of the DIRECT switch on the front panel is missing. The switch itself can be pressed and the LED turns on, so it can be used without any problems. The EQ and master knobs have been replaced. Screws for rack mounting are not included, so please prepare them. In addition, although the operation has been confirmed, there is considerable wear and tear. Please check the images carefully and purchase with the understanding that it is a used item.
