Help!!

The other day I was recording a song with my ibeanz btb bass, I used the Focusrite scarlet audio interface to record. I used the micro phone input with a cable and it worked fine. I then pressed a botton on it that said “48v” (I’m new to the forscsrlet my bass didn’t work after that. I opened it and noticed the battery’s were really hot. Then i opened it and there were two wires that connected that appeared to be a bit hot. My suspension is that it’s a fuse or resistor or something like that since the two wires were disconnected. How should I
Go on?

The "48v" button on the Scarlet sends 48v through the mic cable to power microphones that require phantom power (usually condensor mics). You don't want or need that on bass. If there is an "inst"-specific input on the Scarlet, or a switch to set the input you're using to instrument rather than mic, use/do that, and do NOT engage the 48v button.

Replace the battery or batteries in your bass and try with your amp. If it works, you're ok. If not, I suppose it's possible you fried something onboard in your controls/preamp.

What preamp is it? That could be a fusable link but I’d be a little surprised if it is. Is there anywhere in the control cavity those wires appear to go? Can you find a wiring diagram for the pre or the bass?

Ok, Bartolini. I think that will work without the grey and white leads connected so try fresh batteries. If it doesn’t work do what the instructions say and remove what’s left of the resistor and solder a new 6.8Kohm resistor in there. If that doesn’t work then something is probably fried on the board and most of those are potted in epoxy so they’re not really repairable on the component level.

Phantom power is for microphones utilizing an xlr cable. Your interface does not send phantom power to the 1/4" jack. The focusrite's manual says this: "48V phantom power switch for mic inputs - enables 48 V phantom power at XLR contacts of both Combo connectors." So unless you are using an xlr to 1/4" cable to plug your bass into your interface, the 48v button is doing exactly nothing to your bass.
