    Is there any particular difference in transformers meant for HiFi and those used for guitar/bass amps?

    Bandwidth. And because guitar OPTs are bass limited, they can be a lot smaller.

    I have been told that sometimes it's desirable to drive the guitar amp opts to non-linear range or even to saturation.
    Linear amp opt should operate well below non-linear range of B-H curve.
    For hi-fi amps low winding resistance is important, in case of guitar amps I'm not sure it matters much, so no point in having silver windings there.
    There seems to be little point in having quality core material and thin lamination thickness for guitar amp opt.
    Some guitar amps sound super dull though, perhaps there the opt is too crappy.

    Thanks. I didn't know if there is a difference in winding technique to get some particular tone. Really was just wondering if I could use a cheap Edcor and it seems like I can.

    You can, but good OPTs matter. Bud at Onetics is a good source to contact about it.
