Usability and sounds

The pedal offers adjustable parameters, not just for rotary speaker sound but also reverb.

Two reverb types are available via a toggle switch, delivering great-sounding yet diverse sonic outcomes via a spring reverb emulation that feeds into the rotary sound, or a larger-spaced ambience at the pedal’s output.

Another switch offers ‘Memphis’-style disabling of the spinning of the emulated bass rotor, which can have the effect of making your low-end more focused.

Speed switching options from the dedicated footswitch toggle between slow and fast speeds but can also bring the speaker to a halt when pressed. A Speed knob adjusts the available range by up to 15 per cent up or down, and you can also set how long the Ramp is from one speed to the other.

The basic rotary sound is very convincing, as are the speed changes with the acceleration/deceleration of the horn and rotor proceeding at different rates like the real thing. The pedal can be run with or without cabinet simulation, giving you two different sonic options to start with.

The overall sonic signature can be adjusted to taste by a knob that balances the level of horn against rotor and parameters representing the simulated mic’ing, particularly the Distance control, which ranges between a focused or more diffused effect.

While rival pedals offer a drive feature to emulate the growl of a vintage Leslie valve amp, there’s none of that here, so you’d have to employ a drive pedal for the more driven speaker sounds.

Verdict

Verdict: ★★★★

It may lack some of the connective flexibility of its rivals that have optional stereo input and a designated mono output, but if mono input with a stereo output suits your signal chain needs, it could do the job for you.

Guitar World verdict: The Burn offers a really good representation of rotary speaker sound with plenty of practical sonic adjustments on tap and the added bonus of reverb.
