The GOKKO GK-60 Salem Boost is a compact boost pedal for electric guitar. GOKKO describes it as designed to add brilliance, presence, and harmonic richness to your tone, and positions it for rock, blues, and classic sounds1. It sits in the wider family of boost pedals, where the goal is not distortion on its own but pushing the front of an amp or lifting a solo above a mix.
Controls
The GK-60 keeps things simple with three knobs. GOKKO describes them as giving precise control over the pedal's character1:
| Control | What it does |
|---|---|
| Dirt | Gain |
| Push | Output level |
| Range | EQ |
With Dirt acting as the gain control, the GK-60 can lean toward a grittier edge rather than acting purely as a clean volume lift, and the Range knob lets you shape the tonal balance of the boosted signal1. A single LED indicator shows when the effect is engaged1.
Power and connections
The pedal runs from a DC 9V power adapter with a center minus plug, and GOKKO lists the current draw at 18 mA1. Input and output are both 1/4" mono audio jacks, with the input at 1M ohms impedance and the output at 100 ohms1.
The maker's specifications list only a DC 9V adapter (center minus) for power, with no battery option mentioned. The center minus polarity is the standard for most pedal supplies, but it is worth matching your adapter before plugging in.
Build and size
The GK-60 is housed in a strong aluminum alloy casing that GOKKO describes as built for touring pedalboards1. Its dimensions of 110 mm by 60 mm by 30 mm and weight of 270 g put it firmly in the compact stompbox category, so it takes up little room on a board1. The pedal also features true bypass switching, which the maker describes as giving zero tone loss when the effect is off1.
