Zahnrad 4000pre Available for immediate purchase. No price negotiations (final price reduction). Selling due to equipment consolidation. Operation confirmed, no issues. The exterior is generally in good condition with no noticeable dirt or scratches, but please check the photos as this is based on my subjective assessment. (Serial number in the 1300s, blurred) Please be aware that this is a used item, so those who are sensitive to such things should be cautious. As a bonus, I will include one switch hat (green). It is unused. This is an effector, but it has already been discontinued and its rarity is increasing. How about taking this opportunity? Thank you. Guitar Bass Effector Amplifier
