🤝 In collaboration with Jeremy from Ground Zero Ampworks, I'm honored to present the Ground Zero Ampworks Hellion III NAM pack.
A share of all pack sales go to Ground Zero Ampworks to support Jeremy's amazing work.
The Hellion III is ground-up redesign; a multi-channel, super versatile tone machine. Loaded with new features, stellar build quality & superb aesthetics. The all new Ultraplex channel is an amazing plexi-type circuit that goes from clean to cranked at any volume.
ℹ️ “MultiGlass” - Retubed. Rebiased. Reamped
Everything has been reamped with the factory-fitted KT77 tubes.
The amp was retubed, rebiased & all permutations reamped again with a quad of 6CA7 power tubes with both cabinet loads.
This approach covers a lot of sonic ground & showcases what the Hellion III can deliver.
ℹ️ “MultiLoad” - what’s this about?
The cabinet (or load) a tube amplifier interacts with has a considerable impact on the tone & feel.
For this pack, I used 2 iconic cabinets and reamped all AMP and POW settings with each cab.
ℹ️ Summary
