This is a high-performance effector with a dual-band compressor and TUBESIM mode. - Model: MULTI COMP - Type: Dual-band compressor - Power: 9-18V DC - Mode: TUBESIM - Condition: With active switch Thank you for viewing. I purchased this new in December 2024. I used it about 3 times in rehearsals and 4 times live. After that, I didn't use it much, and I've been carefully storing it at home, but I'm selling my equipment due to marriage. I will sell it to someone who will use it a lot. Thank you. *Please refrain from purchasing if you are nervous or seeking perfection, as this is a used item. *Instant purchase is also possible, but replies to comments may be delayed due to work. Thank you for your understanding.
