🔹 JS – Plexi Ultimate and DI v2

Amp+Cab & DI Tone Models based on the Marshall SV20C Amplifier

 

The JS Plexi Ultimate and DI v2.0 Tone Model Collection is based on the Marshall SV20C, part of the Studio Vintage series inspired by the legendary 1959 Super Lead Plexi.


Delivering the unmistakable tone that defined generations of rock, this compact powerhouse brings the full authority, dynamics, and harmonic richness of the original Plexi into a modern format — now captured in stunning detail for ToneX v2.0.

 

This expanded v2.0 collection includes 40 Tone Models captured through multiple cabinet configurations and DI (amp-only) versions. Each combination explores the amp’s full tonal range across both input channels and volume levels — from glassy cleans to roaring British crunch.
