Soprano Saxophone Mouthpiece GOTTSU Metal HL2018 Opening 7

Soprano Saxophone Mouthpiece - GOTTSU Metal HL2018, Opening 7 (Previous model to the current one)
This listing is for the mouthpiece only; no ligature, case, or other accessories are included.

I received this mouthpiece from a fellow saxophonist in near-mint condition and used it for about 3 years. I am now selling it as I have switched to a different metal mouthpiece.
The condition of the item shows some scratches from the ligature and dullness on the table, but I believe it is in relatively good condition. Please refer to the photos for details.

This is the only series in GOTTSU's product lineup made of tin alloy, and it is said to have been created with the image of the old DUKOFF in mind.

※Please note the following personal impressions.
While the actual sound production is not exactly the same, the tone is quite similar, and it is much easier to play compared to a Dukoff.
I actually used it for sessions with T-SQUARE, and it felt very comfortable. The tone was well-received by the audience and other band members.
