    Mullard EL34 FX1 Versus FX2

    Hi Ron, if you want some midrange magic I will say these Big Brown XF1 will do the job. I like the Dark Brown base because it sounds more dynamic and power base , also the rhythms is the best of all Mullard made EL34s.

    Mullard EL34 FX1 Versus FX2

    Hi Ron, The Mullard EL34 XF1 have four versions and the XF2 also have a few different structure as well, rather to compare them I think it will be better to get the best sounding one. I prefer the Big Brown base over all the others include the Metal one Regards Adrian
