BOSS Tremolo TR-2 Thank you for viewing. *This is a junk item.* No sound passes through without a power supply. Sound passes through when powered on. However, although the BOSS buffer seems to be working, the effect part does not function. No response from the tremolo effect knobs. Given this condition, this is for those who can repair it. Please understand that this is a junk item. No returns or cancellations are accepted. *The price is based on the sales history on Mercari, where a junk TR-2 sold for 6000 yen.* *Same-day shipping is possible.* Ships from Suginami-ku, Tokyo.
