preamp between echoplex and jtm45
keres is a single-amp preamp modeler blending EP-3 Echoplex transistor clarity with JTM45 tube snarl. preamp and eq only — no power amp, no cab sim. asymmetric waveshaping gives crisp transparency at low drive and aggressive tube-like saturation when pushed. tape-style compression adds vintage warmth.
behavior
- low drive (0-0.5): EP-3 transistor clarity, subtle warmth, crisp highs
- medium drive (0.5-1.0): edges of breakup, harmonics emerge
- high drive (1.0-2.0): full JTM snarl, asymmetric tube-style clipping
- sag: tape compression smooths dynamics, vintage feel
- the eq is post-saturation, so boosting mid/presence brings out harmonic content
