As an audio engineer... I'd recommend a combo of EQ and Compression... make sure the compressor is the last item in your effects chain... (as it makes little sense to eq after compression)

Boost frequencies in the 2-6kHz range... and also around the 250Hz range if you like that chunky sound...

Compression should be mild... if you hear your signal "pumping" back off... I would recommend a 4:1 ratio at most... with about 5dB of attenuation... then use the makeup gain to makeup the 5 dB loss...

Use these pedals only during your solos...

I used to use 2eq's and one compressor... one eq for overall sound... the other for solos...
