Hi grip353,
there is not much wiring in the battery/electronics compartment. Most wiring is in the compartment on the other side, which contains all the pots, switch, connectors and so on. Using glue to repair the compartment doesn’t make any sense, because the parts that broke off just fall apart as soon as you touch them. I made a plan for a different solution now. Will take some time to make it happen, but I’ll try. Will keep you posted if it works. If not: the bass can be used without the pre-amp as a standard passive instrument with two volume and one tone pot.
