Come experience the best of both worlds with some extra emphasis right where you need it.\n\nOne of our most-requested legacy reissues has arrived! The VariOboost is one of our oldest pedals, with a lineage that nearly reaches the beginning of our timeline. The original delivered 12 decibels of boost or cut at a user-selectable frequency from 70Hz to 1.4KHz, with some additional gain piled on top for a truly stellar boosting experience. This device was loved by players of all stripes, from jazz players looking to tame highs in a surgical way to death metal guys looking to annihilate the midrange without sacrificing volume. We’ve captured the spirit of the original, with an additional control we call Pre. This new control introduces a clipping circuit before the frequency boost with plenty of gain of its own. Together with the Post knob, you can dial in everything from ultra-clean boost by cranking Post and rolling back Pre, to a very convincing overdrive by turning the knobs the opposite way. You can also give a stubborn amp a shove into the red by running both knobs at whichever level you like. Whether you’re a clean or dirty boost person, we’ve got you covered. Come experience the best of both worlds with some extra emphasis right where you need it.","images":["https://cdn.shopify.com/s/files/1/0370/1873/0628/files/vario-shopify-01.png?v=1728419986"],"price":169.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:04.206Z"},"share_url":"https://firestarter.network/l/lst_AJtcih07","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
