MATCH THE HARDWARE FIRST
Start with the instrument’s own controls
The CE-1 also provides a preamp and signal split. See the documented CE-1 → Major / Silver Jubilee paths. A generic chorus into one amp is a substitute setup.
Equipment basis and value provenance are separate. Suggested values for matching hardware are still not verified artist settings.

Start with the connections. Guitar → modeler INPUT → headphones or FRFR. Use both amp and cabinet simulation. For a physical guitar speaker, disable cabinet simulation and adjust the output mode.
The proposal fits within HX Stomp’s eight-block count. Actual DSP use still needs testing; omit optional modulation if necessary.
Tone and gain values are normalized 0–10 starting points. If the device uses a different range, begin at a similar proportion; this is not an acoustic equivalence. Time, frequency and mix retain their shown units. Leave unlisted parameters at defaults.

Make the final adjustments by ear
- Start at a low output level and check for input clipping.
- Bypass pedals and establish the amp’s basic tone.
- Match engaged and bypassed volume as you enable effects.
- Adjust bass for loose lows and treble or high cut for sharp highs.
