I hear that most mods use pwm where the provari does not. Is the DNA-20 a pwm device? I really don't like the rattlesnake effect.
the provari does in fact use PWM but its at a level that is too speedy for us mere humans to distinguish. heck even on a scope the provari looks like a flat DC signal. the numbers tell the tale: 800hz per second is what the 'vari cycles at. to put that in perspective, the cheap chip that vamos and other similar devices have is 33hz. hence the rattlesnake.
im not sure what Evolv uses to modulate power. it might be PWM at a level comparable to the provari, it might be some other form of modulation. i cant recall.
one thing i can suggest to the OP is the kick. or better yet the kick2. this will give you the supreme modulation that Evolv (makers of the original kicks, opus, darwin, and DNA chips) is known for, but the versatility to use it on just about any mech mod.
then, if you outgrow the kick, youre still left with a mech mod that can go places current kicks cant go. with the provari, not so much. however, even though ive delved deeply into mechs and sub ohms and whatnot, i still use my provari daily.
