Burns Sonic Solid State Amplifiers

Including Baldwin Burns versions

Burns Sonic 50 Front View.png

The Sonic 20, Sonic 30 and Sonic 50 were Burns' more affordable alternative to the Orbit series.

Reworked after the Baldwin takeover and rebadged as 'Baldwin Burns', they were issued as the Sonic 25, 35 and 55. These later cabinet designs gave a nod to Baldwin's own American equipment, but the circuitry stayed British.

For 'Vibrato' read 'Tremolo'.
