Laney LC50 - Normal preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Laney LC50 is a 50-watt all-valve combo with a classic British plexi-style layout rather than switched clean and drive channels. Four inputs feed two ECC83 channels, each with its own volume, mixed into a cathode-follower-driven treble, middle and bass stack. An ECC83 long-tailed-pair phase inverter with a presence control drives two fixed-bias EL34s from a solid-state rectifier, with 8 and 15-ohm outputs.

• Wattage: 50W
• Channels: 2
• Preamp tubes: 3× ECC83
• Power tubes: 2× EL34

Tags: british, mid-wattage, crunch, two-channel.

Schematic-derived preset files for 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.
