This is a hilarious thing: a battery tester that requires a battery for operation. How many will they have sold? No idea... I never ran into an Ibanez branded version, just this Maxon branded unit. But you surely know that they were all Maxon made. It's list price in Japan was equivalent to ten 9V blocks.
