Even in situations where a tube amplifier isn't available, such as with transistor amps or during recording, guitarists can achieve the feel they desire. This is the ultimate solution for guitarists seeking the feeling and dynamics of a tube amplifier. Furthermore, the Nu:tekt series allows for self-assembly, which is one of its appealing features. The TR-S kit requires no soldering and includes the necessary tools. It's the easiest and quickest to assemble among the Nu:tekt series so far. You can enjoy the fun of DIY while getting a compression pedal with the sound and feel of a tube amplifier. Features: ■ Recreates the behavior and SAG of a tube power amp with Nutube A circuit configuration unique to Nutube, which makes the vacuum tube itself perform compression. Replicates the SAG (compression feel), which is the behavior of a tube power amp, with Nutube in all situations, such as transistor amps and DTM. In addition to the four knobs on the panel, three trimmer knobs are equipped inside the cover on the top of the enclosure, allowing for further sound shaping. Natural compression effects can be obtained, so it can be used for instruments other than guitar. Specifications: ● Vacuum tube: Nutube.6P1. ● Connections: INPUT jack (mono phone jack), OUTPUT jack (mono phone jack), DC 9V jack ● Power: 9V alkaline dry cell (6LF22/6LR61 / sold separately), or DC 9V AC adapter "KA181" (sold separately) ● Current consumption: 85mA ● Dimensions (W x D x H): 122 x 96 x 55mm ● Weight: 340g (without battery) I bought this about a month ago, but I didn't really like the sound, so I'm selling it.
