I borught a Jackhammer, but after reading reviews and trying it out it seems a bit to un heavy for me, too much classic sounding.

I was wondering if the DS-1 Distortion would sound more heavy Eg Metallica sounding.

Or it may be the way im setting the dials, are there any dial tunings that could sto me from changing this pedal tomorow?
Just change the pedal imo

no the jackhammer is definitely heavier, but its one of those pedals which you have to spend a lot of time tweaking until you get it right due to it having so many controls - and theres a lot of people here who write reviews who seem to not like the word "tweaking".
I like analogue Solid State amps that make no effort to be "tube-like", and I'm proud of it...

...A little too proud, to be honest.
Do you think going back to the guitar shop and gettin gsome pointers on how to tweak it well will help?
