Hamstead Ascent Amplitude Controller Boost Pedal


Here's what Hamstead say about the Ascent Amplitude Controller:

Ascent is a pure clean boost pedal, offering a huge 20dB of gain with near-zero tonal colouration across the whole frequency range. This is of course coupled with Peter Hamstead’s usual design refinements including ±15v internally isolated power for super high 30v headroom and a VCA-based design for an incredibly linear and transparent boost.

A Boost for the Music Industry

The world has been going through some incredibly challenging times lately, with so many people in the live music industry losing their work and livelihoods due to the COVID-19 pandemic. At Hamstead, we’ve put together a plan so that we can play our part to help. Built by techs from bands including AC/DC, Biffy Clyro, and Iggy Pop, this is Ascent: more than just a high grade, pure clean boost, but a pedal that gives back to the core of the live music scene. Each and every Ascent will be hand soldered, signed and dated by the tech that built it.

Ascent features our standard OptoKick footswitch from Daniel Steinhardt and the team at TheGigRig. They are also partnering with us to contribute 15% of the cost of every footswitch to the cause.

Another key part of the concept is to give techs who are suddenly out of work a project to be creative, providing a distraction from the sad state of the industry that we all know and love. The Ascent project is not just a quick fix, but designed to offer both financial and mental health support to people that make live music happen.
