From the vendor

Project overview

Based on Amptweaker Tight metal. The high gain drive includes an internal noise gate, Tight control, and two switches to select different voice modes such as Thrash mode and our mod on the original model that allows you to select between the stock Tight metal the “more crunchy less gainy” Tight Rock.

Introduction

Right in the face is probably the way to describe this 1590BB project based on the Amptweaker Tight Metal , a high gain distortion that quickly gained fans way beyond the thrash metal players with its tweakability, the fat chords, and the leads that cut straight through a mix. It also comes with a switchable built-in noise gate. Another Switch to change the mid response, and last but not least, we included an additional switch to mod between the stock Tight Metal and the mod Tight Rock.

You thought we are done yet after all that switches, didn’t you? Nope, the five Potentiometers do not only take care of the amount of gain, volume, tone, and the gate. There is one left to dial in the amount of tightness. This knob is handy when you´re down-tuning your instruments.

With many components, many pots, and toggles, this is definitely not a beginner project, even if we try to keep the documents as easy to follow as possible.

We proudly can say the Solid Metal PCB is something you’re not getting everywhere. So if you build some pedals before, you should grab one of these while they are hot.
