Union Tube & Transistor MORE Summit Boost

Introducing the Union Tube & Transistor MORE Summit Boost Get ready to elevate your guitar tone to new heights with the Union Tube & Transistor MORE Summit Boost. This pedal is not your ordinary boost—it's a guitar preamp that can deliver a wide range of clean gain, from a subtle +5dB to a whopping +40dB. Union Tube & Transistor has taken their acclaimed MORE boost pedal and created an extremely limited "Summit" edition in a sleek grey and yellow colorway, with only 20 units available.

Versatile Gain Structuring The MORE Summit Boost is your ticket to a dynamic tonal experience. It offers a maximum undistorted output level of +16dBu, making it ideal for use with a tube amp. Whether you're looking for a subtle volume bump to make your guitar punch through the mix or aiming for a full-on sonic assault, the MORE Summit Boost has you covered. Its versatility shines when used in various scenarios, from solo performances to sweetening your overall tone or pushing the limits of your amp.

Perfect Placement and Settings To harness the full potential of the MORE Summit Boost, consider its placement in your signal chain. It can add beautiful gain structuring when used alongside overdrive or distortion pedals. However, be mindful that cranking it to the max can push digital pedals to their limits. For optimal results, place it just before your tube amp or at the end of your pedal chain.

Powerful Performance The MORE Summit Boost is a pedal that demands attention, and it runs on a standard 9V center-negative adaptor. With a power consumption of 45mA with no signal and 52mA at maximum output (+16dBu), it's ready to unleash a sonic storm while remaining efficient and reliable.
