AXiom XB-1 XFMR Boost Analog Transformer Emulator
CAPACITANCE
GAIN:
Increases the signal level into the xfmr emulation circuitry as the knob is
turned clockwise (CW). Used to trim hot input signals and boost weak ones into
the ‘sweet spot’.
CORE TYPE:
Adjusts the transformer core from high Nickel through 50/50 nickel-steel to
a high Steel core. High nickel cores distort (saturate) the least and have the
cleanest low frequency response. High steel cores saturate the most and
distort furthest into the high frequency band.
BOOST:
Adds up to 10dB of clean level gain when the BOOST footswitch is engaged.
LEVEL:
Increases the output signal level as the knob is turned CW.
SATURATION: Increases xfmr core saturation as the knob is turned CW. In
the fully counter-CW position no saturation will occur and the XB-1 will
function as a clean boost.
PERMEABILITY:
Increases core permeability as the knob is turned CW. High permeability
cores have the strongest bass response but also saturate more easily.
CAPACITANCE:
Increases the winding capacitance as the knob is turned CW. This has the
effect of reducing treble frequencies.
TIP:
To increase clarity and note separation, set the CORE TYPE between Nickel
and 50/50 and increase SATURATION until just before the audible distortion
point. Use GAIN to fine-tune the response.

The AXiom XFMR Boost XB-1 is the industry’s first 100% analog transfor- mer emulator boost/buffer pedal to precisely recreate the harmonic profile and frequency response of audio transformers. Xfmrs are well-known for im- parting a clarity and “sweetness” to the sound that, until now, couldn’t be got- ten any other way. They can also get downright nasty when pushed hard. So why not just buy a real xfmr? Well, unless you deliberately buy a ‘dirty’ one, you’ll likely have trouble pushing it hard enough to be noticeable. And then what if you want a more transparent one? Buy another? What if your humbuckers push the xfmr to where you like it but your single-coils don’t? The XFMR Boost XB-1 recreates the harmonic content and overdrive charac- teristics of real transformers… and gives you precise control over them. It can go from a buffered clean signal, to a subtle increase in clarity, to a notice- able edge on your tone, all the way up to the sound of a very, very hard- pushed distorting mic preamp. Plus, it has a dedicated footswitch with up to 10 dB of clean level boost for solo breaks
