Tuner bypass -> Earphones

[Humph]

Hi guys, long time lurker here!

I'm playing in a production of Evita in April, and was wondering how to best monitor myself as I'm sure the sound team will want to keep pit noise to a minimum. I've worked with some great sound guys but I'm not prepared to rely on the PA system + monitors (which are often in short supply) to hear myself

So I was thinking of routing from my Boss TU-2's bypass output to my earphones. Will this work? Or would I need a mini mixer to balance the signal?

Thanks guys,
Adam

Mixer to balance signal

There won't be sufficient volume from the tuner to drive the headphones.
Something like the ehx headphone amplifier would be ideal
