In perfect condition/ like new.

This is the best kept secret in the synth world at the moment....seriously!

While this is being marketed as an "educational synth" , it is really a super capable modular in a single enclosure, with the best big knobs and user interface in the category. You also have the ability to do sample looping via one of the plug in cards (included) as well as plugging in the Sequencer card or Acid Bassline card for further explorations. There are even a few DIY cards to create your own presets.

Check out the TY link I attached to get an idea of what this synth can do....The Moog Mother-32 only wishes it could do all of this (I own the Mother-32 and love it by the way)

Bullfrog is a classical subtractive synthesizer – it consists of several “modules” for sound generation – VCO, NOISE GENERATOR - and treatment – VCF, VCA/DELAY, as well as “modules” that generate control and modulation signals to control them – ENVELOPE GENERATORS and SAMPLE & HOLD. The Bullfrog will not make the sound on its own unless it is patched – using eurorack patch cables to interconnect the “modules” or by inserting voice cards that create internal connections between the “modules” in a specific way and add extra functionality, like sampler/looper, sequencer, groovebox, etc. This approach better helps to understand the functionality of a subtractive synthesizer and the principles of sound design with instruments like these.

What’s included:

• BULLFROG synthesizer
• Universal 12VDC wall wart adapter
• User manual
• 10 patch cables
• 3 pre-patched voice cards: Sequencer, Acid Bassline, Sampler Looper
• 3 DIY voice cards

In order to provide a well-rounded understanding of the functionality of this synthesizer and sound synthesis in general, a comprehensive user manual is created to accompany the learning process.
