The Custom GS-50 is the flagship Scholz amplifier platform, built around our GS high-gain circuit and engineered for players who demand clarity, punch, and musicality at any level. Powered by a matched pair of 5881 output tubes, it delivers a fast, authoritative low end, rich harmonic drive, and a responsive feel that tracks every nuance of your playing.
This is not a generic high-gain sound — it’s a focused, articulate voice designed for professional use on stage and in the studio.
Grand Master Attenuator — Output Stage Control, Without Compromise
Integrated directly into the power section is the Grand Master Attenuator, a custom transformer-based system that provides five precise steps of 6dB attenuation with no loss of tone, feel, or bandwidth.
It maintains:
- Low-end strength
- Harmonic complexity
- Transient response
- Presence and articulation
at every volume setting.
Players can run the amp where it sounds best — loud, dynamic, and open — in any environment, without flattening the tone or relying on compensation filters.
It’s a level of control that simply hasn’t been available in guitar amplifiers until now.
Two Inputs, Two Professional Voices
High Input – GS High-Gain Circuit
A saturated, controlled drive with clear note definition and strong midrange presence.
It excels at focused crunch, articulate high-gain rhythm, and expressive lead tones — tight, physical, and highly responsive.
Low Input – Wide-Bandwidth Clean
Inspired by classic high-headroom circuits, but expanded with a wide, open frequency response and a Hi-Fi-like clarity that makes chords feel three-dimensional.
It’s not sterile — it’s musical, airy, and stable under dynamics.
Reverb Designed as Part of the Instrument
The custom Scholz reverb circuit is tuned to blend with the core tone rather than sit on top of it.
Low settings add subtle width; higher settings create a deep, immersive ambience that remains controlled even under heavy gain.
It feels natural because it’s engineered as part of the signal path.
