Fatness booster?

Hi, I was listening to the demos of the new-ish Thorpy The Dane pedal and the drive side sounds okay, but the boost side sounds great because of that 'low' knob. Could an EQ achieve a similar effect to the low knob or is there some socerery in fattening up the sound?

sort of... the boost also seems to be compressing/clipping itself a little whereas graphic EQ pedals are designed to be relatively clean and dynamic... its the opposite effect of a rangemaster, a compressed, dirty boost with a low shelf... this is like a compressed dirty boost with a high shelf or lower mid bell... idea's as old as the hills! personally my experience with thigns like this is that a lower mids and bass sound good on your own but are a terrible thing to boost in a band context. Even on a recording the first thing I do is high pass the guitars somewhere between 80 and 120 c/s, the enxt thing I consider is dipping the low mids for mush between 250 and 500 c/s. Most recording/FOH engineers will do one or both of these thigns to clear up the mix for the bass and the drums. YMMV though. If you think it's really cool you can find lots of cheaper options in the low boost style... or try a sola sound overdriver/powerbooster type circuit, a dirty compressed boost/fuzz with a great treble and bass tone stack so you can dial it in like a very gentle EQ before the amp.

Ah, so more of a sound nice at home pedal rather than a live one?

that's my thoughts on bottom boosters, but YMMV sicne it cna eb very guitar and amp dependent... you play a hot rod, right? big bottom there and mroe midrange then blackface fenders... still, light lwoer mids overall. Maybe it would be cool if you were playing with your bass way down. You could go to a store and try it through a hot rod ;-)

will do, i've learnt that if possible try before you buy tends to be the best option

Perhaps if you run the EQ before your drive pedal(s), you could get the beefier low-end you want, as well as pushing your drive pedals and the amp in a more natural sounding way, rather than just adding bass on after its been clipped by a drive pedal.
