The Guts is a two transistor, linear boost. Simple Loud and Guts controls for level and drive for clean(ish) to pretty, damn dirty with plenty of output. It has an open character, working well as a boost, adding some grit, pushing an amp or stacking with other drive and fuzz pedals without squashing things. Just some Guts, really!
Travesfx pedals are handmade in Brisbane in limited runs or to order.
