The Z-Amp is a rather cool-looking concept guitar amplifier designed by Aki Hirota. By casing it in a curved piece of coloured ply-wood he's inadvertently coined the phrase Wife Acceptance Factor (WAF).
Because it looks nice, your disapproving wife won't mind it taking up space in the living room, we presume. No, that's not a sexist point of view at all.
Regardless, if WAF is a priority, those protruding tubes will have to go so 'er indoors will be fooled into thinking you've brought the world's most expensive footrest.
