I agree with sir Vaisteen. Bro, here's my approach with EQ'ing on Zoom 606.
If you have a strat, here are the best EQ settings for you:
Using the lead patch for high gain .
36-for that smooth lead guitar tone, set it to toggle switch 2 on the guitar
25-flat round setting on pickup 1, medyo bilog ang tunog mo d2 pero muddy rin ng konti
42- for that stack sound you want to hear
10-15-para sa in your face riffing using the distortion tone
so far un muna sir...this is your gear....use it well...learn to love it...and gas for more....
