I have an Applied "Big Bass" petal that pot codes to 1967. Its identical to the Goya "Boom Box" petal of the same era. Its not in the prittiest shape but the only things that seem to have been done to it are that the battery attachment looks to have been replaced at some time and there is a nut/bolt in the petal to hold the battery holder in place...I guess the weld failed at some point and a previous owner looked for a quick fix. Works great, looks like crap. Interested to know if any guitar or bass players here would be interested in buying this off me or if I should dump it on the bay...
