What is it

Calling Boss’s Katana range of modeling amps a success is undercooking it somewhat: it’s made the Japanese company become one of the biggest amp manufacturers in the world. But it also presented a problem.

A Positive Grid Spark Mini amp with a smartphone

$1189/£179
The Katana-Mini’s closest rechargeable 10-watt rival in terms of value is a different proposition in form and functionality. There are no onboard EQ controls or effects selection on the hardware; you choose your amps and signal chain the Spark App and save as one of four presets. The selection of models is impressive and the app has jamming and learning features too.

Yamaha THR10II

$439/£348
Yamaha was early in realising the demand for small practice amps that could also look stylish in your home. This rechargeable 20-watt combo is part of the second generation range with 15 guitar amps, 3 bass amps, 3 mic models for acoustic-electric guitars, and a flat response mode. There are eight effects too, and it’s looking pricey now next to the competition but offers undeniable quality.

Fender Mustang LT40S

$199/£219
No Bluetooth or battery power here and some controls need Fender’s app, but you do get a 1.8″ colour screen, 40-watts output and the strength of Fender’s modelling of its own classic amps alongside a strong selection of effects.
