Gearank Recommended

The Katana-100/212 MKII first appeared on our recommended list for Guitar Amps Under $500 in July 2020 where it remained until July 2022 when it was no longer available for less than $500.

In August 2020 it also went on our list for Solid State Guitar Amps where its high ratings have kept it ever since.


The Boss Katana-100/212 MKII takes the Katana Series’ focused amp modeling and effects concept and make them available for big stage and big venue use.

At 100 Watts and with two 12″ speakers, this combo amp can go really loud, while maintaining the features that make the Katana series highly rated: having fewer but high quality amp models, and the inclusion of Boss effects right on the amp.

In addition to the built-in controls on the amp itself, the Katana allows for deep editing via software editor, and all these digital sound processing features are based on the same technology that Boss utilizes on their popular guitar processors.

Finally, this stage amp can easily be transformed into a practice amp with its power attenuator, which lets you turn down the power from 100W to 50W, and down to 0.5W.

With Boss’ reputation for quality and reliability, the Katana-100/212 MkII is a great choice for those who are looking for a workhorse all-in-one amp.
