I'd personally look for a used Digitech DF-7, but it is inexpensive new, and works for over the top metal tones

The boost function is a bit of a secret weapon of this pedal, is can be used as a “cutting through the mix” switch, but is actually used best with it on at around 12 o’clock and the treble knob being on zero, this will give you a very satisfying smooth distortion tone

Has a really good metal tone and the boost is handy

Lots of sweet crunch and cool tones, with quite a bit of versatility

Dialing way down gave a sweet Nearly clean David Gilmour "Breathe" tone

dads at all the local dive bars and roadhouses always compliment my "tone" and my secret is i just use this pedal turned all the way up
