The transformer seems a very simple object, basically it is made by two coil of wire winded around a steel core. The two windings are called primary and secondary.
Its task is to transform the amplitude of the signal to the ends of its windings without modifying the signal itself. But, something happen during this process, and we can achieve some cool Tone from this.

An ideal transformer will just transform the signal without modify it, but a real transfomer has some limits due the loss in the windinds, the resisntance of the copper, the capacity and the inductance of the winding himself, plus the interaction between the windings.
A complete description of the behavior of an audio transformer would be too long and complex to deal with here. The important concept to understand is that the geometry of the winding greatly affects the frequency response of the transformer itself and therefore the sound we get.
We worked on this for design out transformers and let them sound as we like. Look at the frequencies response of our FJOD, bold line is with the output transformer, thin without it.
The two lines are not parallels, you can see a presence boost on the mids [400Hz-2kHz) and a cut on the hight treble; plus a difference output level due the ration between the primary and secondary winding.
