please read carefully. tact switches for 90s Roland synths. These will replace the two pin tact switches on models such as mc307, jp8000, mc303, mc505, eg202, jp8080 and many others. These will NOT replace the 4 pin variety. I have also used these on cdj1000s mk 1-3 to replace transport controls such as play, cue and all that section. it is up to the buyer to determine suitability before purchase, if in doubt leave it to somebody who knows what they are doing.
