I recommend that booster because of its ability to boost the mids, and highs if you pump it up past 12 (a little trebly, so beware). Thing about it is also the ability to ensure your signal doesn't get lost through the longer wires to the amp (which would really be a waste after all that work to achieve the desired tone, hence no true bypass).
An overdrive to boost is a good idea, but if you like your current tone, maybe a booster/overdrive with more transparency is recommended, in case it alters your tone. An EQ pedal is also a great idea. +-15 decibels should be sufficient.
