These amps look a little different than others I have seen, most I have seen were from older batches though. The main difference between these and others I have seen are 1. There is a white dot on the head above a score in the neck, 2. the aburaihan logo is not filled in black, 3. Enanthate is spelled correctly and there is a mfg and exp date on each. Havent seen any that look exactly like these searching online, so just wondering.
