The flagship clean booster from Valkyrie Spear, a Japanese handmade brand that's currently creating a huge buzz on social media, has arrived. Featuring a fully discrete circuit using carefully selected parts and a unique circuit board combining vintage components, this high-quality clean booster delivers a thick, glossy boost while preserving the texture of the original sound. With its wide-range, original-sound-focused design, it pairs well with digital effects pedals and other devices, allowing for a more delicate and lifelike expression of string pitch when fingerpicking or picking. While inheriting the powerful and lustrous tone that preserves the original sound, a characteristic of the Valkyrie Spear, it is equipped with two adjustment functions: 'Brightness control' and 'Gain switching DIP switch'.・Brightness Control It allows you to adjust the pitch and mildness while maintaining the fullness and richness of the low frequencies. It is also effective in reducing touch noise during recording. Furthermore, by completely turning down the trimmer, you can obtain an analog feel as if the sound has passed through a filter, as well as a warm, soft tone. • Gain selector DIP switch The default setting is High Gain, which delivers maximum performance as a booster. If you don't want to increase the gain due to your pedalboard or amplifier setup, you can switch the DIP switch to Low Gain and set the knob to minimum to achieve unity gain output (0dB). This is recommended when you want to add richness, fullness, and thickness to your sound without increasing the gain. Because this unit uses a discrete circuit configuration, it supports a wide power supply voltage range of DC 9V-18V. The sound characteristics will also change depending on the power supply voltage, so please find the sound you prefer and use it accordingly.Specification Category: Boost Pedal / Clean Booster Model: Violence Booster MK-X Size: 50 x 95 x 50 mm • Knobs: Gain adjustment, Gain DIP switch (located inside the case) Switch between High Gain (+3dB?) and Low Gain (0dB?). *Unity Gain compatible: Low setting + minimum knob.
