Tune Active Circuit GAP-1 Bass Preamp (Junk)

【About the Product】
This is a discontinued preamp that was originally installed in a Tune bass.
It's the circuit that creates Tune's signature sound – a sound that fits into any genre while still shining through, with no elements to discard.

This item is being sold as junk because a battery leak caused a short circuit, rendering it inoperable. We hope you can use it for parts or repair it for use.
Before the leak, when it was last used about a year ago, there were no crackles or noise, and it was used normally for recording. (We cannot confirm the extent of the damage from the short circuit as we have no means to test it.)

We cannot accept refunds or returns, so please bid with the understanding that this is a junk item.
The exterior is in good condition, but please check the photos for details.
