1/4" trs To Female xlr Input Jack

[tube power]

Is this correct?

[Jazz P Bass]

Balanced TRS

Looks good to me.
On TRS plugs, the tip is "hot" (positive), the ring is "cold" (negative), and the sleeve is ground (earthed or chassis).
In an XLR connector, pin 2 carries the signal with normal polarity, and pin 3 carries an inverted version of the same signal. Pin 1 is ground.
