Electro harmonix V7d Big muff from the 90s. This is the rare transition model with the large enclosure same size as the earlier green russian. Has a few scuffs and dings but works perfect. No scratchy pots or jacks. No mods just replaced the plastic nuts on the input and output jacks because the originals cracked and added a nylon washer to the footswitch so it wont come loose over time. Has the battery door. Will ship insured signature required on delivery.
