Despite its low output of only 0.1W, this amplifier drives the vacuum tubes with a solid 250V. This allows you to practice at home without worrying about your neighbors' eyes, or rather, ears. And that's not all! You can even connect it directly to a mixer or amplifier via the line out! By using the send/return and connecting it to a power amplifier, you can output the vacuum tube sound you've crafted at home at a large volume. Moreover, it's not just a regular preamp; it's the sound after passing through the output transformer. The output transformer is such a crucial part that some say, "The sound of a vacuum tube amplifier is actually in the output transformer." There's no other product that allows you to connect to a power amplifier through an output transformer. You can even record the sound of a real vacuum tube amplifier in DTM without having to use speakers.
