Solid Metal Pro

From the vendor

Project overview

Our take on the Amptweaker Tight Metal Pro is a super adaptable build that includes dip switches to select between the Tight Metal and the Tight Rock version – or to make your own custom version.

This is by far one of the most versatile Drives we have ever made – If you liked the original Solid Metal, you are gonna love the new Solid Metal Pro!

Introduction

The latest high gain machine from Amptweaker-the Tight Metal Pro, redefines rock/metal tone and the very definition of total sonic brutality.

The design made by the iconic high-gain amp guru James Brown not only comes with a full assortment of high-gain tones and switching capabilities but includes Depth Finder and DeFizzerator processing built in for even more tone sculpting abilities.

We took the concept to the extreme by adding even more features to achieve the ultimate “Right in the face” moddable high gain distortion build. We kept this model under development for quite a while to ensure that it would include most of the features in the original unit + some extra ones. And boy, it paid off!

This final version incorporates the following:

• Noise gate

• 3 band active eq

• Boost

• Individual fat toggles for Drive and Boost

• Mid Boost

• Plexi Eq toggle

• Edge toggle for smooth mode

• High gain toggle

• Order switch for the drive and boost

• Sidetrack loop jacks

• Universal loop jacks

• Boost Loop jacks

• Universal loop pre/ post Toggle

The parts required for this build are quite common and easy to get – no fancy parts besides the four 4PDT Switches (Two toggles, two footswitches).
