The Hotone Skyline Series TREM stompbox is so small and lightweight that it can literally live in a guitar case or bag, yet still deliver premium effects. The Hotone Skyline Series TREM was inspired by the legendary Fender Twin's tremolo. The special circuit design ensures the consistency of output volume at different speeds. You have even more options for sound decoration with the additional EQ circuit. The HARD button adds a darker edge to your tone. The compact, easy-to-use design features a metal footswitch and analog-style parameter knob so you can really tweak your tone. With its pronounced LED, the TREM will shine bright on a live stage. The minature sized TREM makes a great addition to any existing pedalboard where space and weight are at a premium, while the true bypass design lets you build the the lightest, most compact pedalboard imaginable using multiple Skyline Series stompboxes. Don't let its tiny size fool you, the Hotone TREM is built to last with a strong casing and a metal bar to absorb the most emotional stomps that your passion unleashes. 9VDC power supply optional.Features:True Bypass FootswitchOptical tremolo pedal for producing warm tonesDepth and Color parameter controls for shaping tonePush-style HARD button adds darker edgeMain light-up knob adjusts overall tremolo effect speedZinc Alloy Outer Cover9v power supply required (not included)Please note: You cannot use a battery with this pedalOrder your Hotone Skyline Series TREM Optical Tremolo Pedal from Sam Ash Direct today with the security of our 45/60 day return/price protection policy, and be sure to take advantage of our fast, free shipping.
