This is a mini booster with the highest sound quality. I am selling the Ibanez BT-MINI, a mini-sized booster. I purchased this item as a new, unused item and it is in beautiful condition, having only been tested **once (approximately 3 hours)** in a band rehearsal studio. All original accessories at the time of purchase are included, such as the box, instruction manual, and warranty. Features of the Ibanez BT-MINI The biggest appeal of this booster is its clean boost capability, **"raising the sound pressure without polluting the sound."** * Equipped with JRC MUSES8820 op-amp: Produces a clear and bright sound with little distortion. Boosts the original tone of the guitar as is. * Equipped with 2-band EQ: With the BASS/TREBLE knobs, you can not only increase the volume but also make detailed sound quality adjustments. You can easily emphasize the mid-range during solos. * Powerful boost of up to +24dB: Also ideal for pushing the power amp to obtain a sticky saturation. Condition and Accessories * Condition: Beautiful condition, only used once in the studio after purchasing as a new, unused item. * Operation: Good. * Accessories: Main unit, original box, instruction manual, warranty (all included) Instant purchase is OK. Thank you very much!
