Tailor-made for Your SYN-30 Amp Head

The SYN-112 is the perfect match for your Synergy SYN-30 amp head. Loaded with a Celestion Creamback speaker, this 1 x 12" extension cabinet delivers a robust British sound with open cleans, brutal crunch, and singing leads. This cabinet is sure to bring out the best in your preamp modules — lows will sound full, mids will be creamy, and highs will chime beautifully. The SYN-112 features a semi-open-back design and durable Baltic birch construction.

Celestion's Creamback speaker delivers classic British sound

Celestion's Creamback speaker gives you classic British tone, with enough power handling for today's powerhouse amps. In the 1960s, Celestion's original Greenback speaker helped shape generations of guitar tone and became a staple of modern music. With its warmth and distinctive growl, the Creamback serves up the essence of British guitar tone, with low-end grunt complementing its warm mids, crunchy upper-mids, and sweet highs. If you want definitive Celestion sound, then reach for a Celestion Creamback.
