Description
Roadhouse USA:
2025 Trainwreck KR-684 6-EL84 Tube Amp Head.
Brand new KR-684.
Her name is Charisma.
Goncalo Alves cabinet with a wonderful Flame Maple face.
From John Mark:
Charisma is a 6-EL84 output tube amp that utilizes a tone stack. It has a strong overdrive ability while maintaining lively harmonic content and great note separation at high gain. The stages are voiced for the tone stack which drives the phase inverter. The ‘Presence’ control functions something like a ‘cut’ control which is located post- phase inverter.
The phase inverter is uniquely designed to culminate in the amplifier’s voicing, providing a full rich sound along the entire Master Volume range.
‘This amp does not use negative feedback’.
The EL84 output tubes tend to have a more mid-range scooped characteristic which we’ve balanced with a wider range EQ, yet still maintaining the high-fidelity clarity that is characteristic of the Vox AC-30.
Yes, these amps are everything you have heard they are and then some:)
One of the most beautiful cabinets I have had on one of these amps, John and Danny always use the best woods available when they do these builds.
If you have never played a Trainwreck, you need to. These amps are the absolute pinnacle of handmade tube amps being built today.
