Roland CK-100 - Channel 2 preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Roland CK-100 is a solid-state keyboard amplifier, not a guitar amp. Two inputs, each with a pair of jacks, get their own op-amp preamp and volume control with a pull-out attenuator switch, then mix into a shared bass, treble and middle EQ. A discrete transistor power amp on a split supply drives a three-way speaker system of woofer, squawker and tweeter through a crossover network, with pre-out/main-in, line out and headphone jacks.

• Made in: Japan

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.
