Eastern Eastern preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Eastern is a small single-channel valve guitar amp, similar to the Silvertone 1301. One input feeds a volume control and two cascaded 6SL7 triode stages, then an unusual tone circuit at the output valve's grid, driving a single cathode-biased 6V6GT in single-ended class A straight into a speaker-mounted output transformer. A 6X5 full-wave rectifier and an 8/16/16 µF filter chain supply it, with no negative feedback.

• Channels: 1
• Preamp tubes: 1× 6SL7
• Power tubes: 1× 6V6GT

Tags: vintage, 6v6, class-a, low-wattage, clean.

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
