Gearank High Notes

The Marshall Code 100H appeared on our recommended list for Modeling Amps in 2 editions from August 2020 until February 2021 when it was removed due to a lack of availability.


It may seem odd to see Marshall’s name side by side with ‘modeling amp’, but this is no mistake, Marshall has received good reviews for their DSP capable Code series amps.

The 100-Watt amp head CODE 100H is one of their top rated offerings, it carries over the same amp modeling and digital effects found on other CODE series amps, only this one is in a head form factor so you can match it with a speaker that you prefer.

Instead of modeling specific classic amps, the CODE series lets you mix and match preamp and poweramp models, allowing for even more flexibility in tone shaping.

This can also be coupled with speaker cabinet models which further expands your tone options.

On the effects side, this amp lets you choose between 24 effects, including compressors, distortions, modulation, pitch shifters and even auto wah.

Finally, this amp head comes with modern connectivity including Bluetooth and USB.
