Boss are a generic brand...and their distortion is the worst offender

electro-harmonix are the best mainstream pedal brand ive encountered
if you've got the cash go for a zvex box of rock or some beautiful (and hugely expensive) boutique thing

but the Big Muff is brilliant and gives you a way more interesting sound than the ds-1 ever could (ive had both) also way more grind.
there is no reason you're g&L cant be a filth beast
