Description

Overview

Catalyst Reaction – Ember / Sapele Build #003

Handbuilt semi-hollow electric guitar finished in nitrocellulose lacquer. Ember is the thicker-voiced Catalyst platform: warm mids, vocal lead tone, and that semi-hollow “breath” — without losing definition when you lean into gain.

This guitar is fully built, professionally set up, and ready to ship.

Builder Notes

The Catalyst Ember is tuned for thickness without mud. The semi-hollow construction is achieved by routing internal cavities rather than pressing laminated plates. Acoustically, the response is lively and high-mid-forward, with a quick initial attack from the bolt-on neck joint. Brighter than a Gibson, but warmer than a Fender.

A standard master volume, master tone, and three-way switch provide flexibility while keeping the control layout simple and intuitive.

The body cutout sits naturally on the leg for comfortable seated playing, while the semi-hollow construction keeps weight under control and balances well when standing.
