I have used the primary of a small push pull output transformer for that purpose with good effect.The ElectraPrint PSA-2n Phase splitter auto former (that's what Jack calls them) was better for Hi-Fi though.
Mike has one also. EXO-173 PPS Ni

I tried a design for a phase-inverting center-tapped secondary transformer driven by a single-ended cathode follower, and found it hard to get good balance at high frequencies (above a few kHz) between the two ends of the secondary. This is probably something you should measure with the transformers you are using.
No way to measure, all I have is my ears and a DMM.
According to a chart I found, a guitar's fundamental range is roughly 82 hz to 1.2 khz with harmonics going up to about 5 khz.
