SUPERBOOTH 2024: Erica Synths have gone large at Superbooth 2024 - literally.

Following last year's introduction of its educationally minded single-oscillator synth, developed in collaboration with techno royalty Richie Hawtin, the Latvian firm has whipped a very large cover off of Bullfrog XL, a slightly augmented, but more importantly superized, iteration designed specifically for classroom use.

When the original was announced, Hawtin said "We believe that the hands-on approach and problem solving that is innate to synthesis on a semi-modular synth like the Bullfrog, contains life lessons that go beyond what we can hear."

The newly inflated version, Bullfrog XL, is 3 times the size of its predecessor, measuring 820mmx505x65 (250 with the side panels) and weighing in at just over 8kg, and adds a few key educational features, including the oscilloscope you see at the top of the unit.

Bullfrog XL is available direct from Erica Synths now, priced €1,700
