The MESA/Boogie Express 5:50+, which is currently difficult to obtain! Its biggest appeal is that it can handle everything from clean to high-gain sounds in a single unit, while building on the foundation of the so-called "sound of a good tube amp." It has a 2-channel configuration, with modes for each channel, and you can instantly switch between CLEAN/CRUNCH and BLUES/BURN with a footswitch, making it ideal for situations where the "role of the tone" changes during a song. Original price: 309,750 yen The output switching is easy to understand, with 5W/25W/50W (5:50+) allowing you to scale the volume range. You can enjoy the push of the tubes at 5W at home, and secure headroom and sound density at 50W in the studio or live, allowing you to "adapt to the situation while maintaining the same character." Furthermore, the long spring reverb has independent volume controls for each channel, and it also includes a 5-band EQ/Contour, a Solo boost to bring the sound forward during solos, and a buffered FX loop that doesn't muddy up spatial effects, making it highly effective for sound creation and practical use from the start. In terms of sound nuances, the clean sound has good clarity and chords don't get muddy easily, CRUNCH has a "box-like resonance" and crispness, BLUES has stickiness and luster, and BURN can create a lead sound that is thick and sustained. It responds well to the strength of your picking, so I think it will appeal to those who like amps that retain expression even when distorted. The exterior is in beautiful condition. As the photos show, it's a clean unit, so it's recommended for those who want to welcome a "tube amp that can be used on stage" with a good feeling. Footswitch included. Please check the photos carefully and understand that this is a used item, although it is in good condition, before purchasing.
