Vintage 1980's ROLAND TR-505 Rhythm Composer. All Functions That were Tested, Work As They Should. MIDI In/Out, Tape In/Out & Foot Switch are UNTESTED, I don't have the capability to test these functions-SOLD AS-IS. Minimal Scratches & Dis-Colorization (See Pics for actual condition). Read-Out Screen in EXCELLENT Condition (see pic). Battery Compartment is Clean-Appears No Batteries were stored there (see pic # 9). ISSUES: 1) Battery Compartment Cover fits a little crooked (see pic # 10). 2) Back panel is missing Labeling Decal (see pic # 11 for specific reference). 3) 9v AC ADAPTER Is NOT Included. Battery Function is UNTESTED. Overall Excellent Condition! GREAT SOUNDS!
