【エフェクター修理】BOSS DS-1 エフェクト掛からず。電源誤入力？

BOSS DS-1 repaired. It is a little bit old and made in Taiwan. Various internal parts seem to have been blown off due to a wrong input of the power supply. The equipment used in the latter half of the review was Kiesel A6, Laney GH-100L, and UA OX AMP TOP BOX. Please do it at your own risk when you do the repair yourself.
