Generally speaking the lows are the area of the frequency range where build up can quickly create the most distortion and mud. But not always perceived as distortion, but more as just being less clear in the lows . And as counterintuitive as it may seem often a judicious low cut can clean things up enough that uncut lows sound more distinct and thus better.
Generally speaking a 2 mic stereo recording (particularly of a solo instrument) will have bigger sound with more horizontal spread to the sound ( as long as the two mics are in a relatively close phase relationship.
Also if you are recording with a DAW that has an EQ with adjustable multi band option, you can also cut some of low build up with more flexibility as to where to start the roll off in the frequency range, like as Fran noted at 200 hz or 150 hz or100 etc. depending on what particular guitar/room /mic /preamp combination.
