【Overview】 The Maxon PUE5B is a programmable multi-effects unit for bass guitars manufactured in the late 1980s. It is now discontinued and is known as a hidden gem of Japanese vintage gear. 【Effects Functions】 It features five effects: compressor, EXT.LOOP, graphic EQ, digital delay, and flanger/chorus. 【Features】 The combination of analog circuits and digital delay/chorus achieves both warm analog sound and clear spatial effects. The compressor, in particular, is praised for its punch and is well-suited for funk bass lines and slap techniques. 【Other】 It has a headphone jack, allowing for practice at night. It is powered by a standard 9V DC adapter. 【Support】 The Maxon official website provides a support page where you can download the PUE5B user manual (PDF). http://www.maxon.co.jp/support_n/download_n/userguide_discontinued_effects/Maxon_PUE5B_Manual_SS.pdf 【Product Condition】 As shown in photo 2, power has been confirmed. The adapter used for confirmation is not included. (This is a sale of the main unit only.) As shown in photo 5, one of the EQ knobs is missing. There are scratches and signs of use associated with use, but it is in very good condition considering its release date. Of course, there are no operational problems. As it is very old equipment, normal maintenance is possible, and we ask that you purchase it with an understanding of used items. With normal use, there may be some scratchiness in the knobs or poor contact during connections, but this is not completely zero. It usually recovers by reconnecting or moving the knobs. (There are no interruptions or noise troubles during performance.) Returns, refunds, and support are not possible after shipping is completed. Shipping is planned via Yamato Transport. (Tracking, insurance, and time designation included) Please consider the above carefully before purchasing. If you have any questions, please feel free to comment. Please note that it may be removed without notice due to various circumstances.
