Celestion Speaker Shaper

Softube Celestion Speaker Shaper is a guitar and bass cabinet modeling effect that lets you design speaker tones instead of relying on fixed impulse responses. Officially licensed by Celestion, it offers eleven speaker models with adjustable sizes from 8 to 24 inches. Run two cabinets in parallel, then shape their response with controls for speaker breakup, impedance, magnet type and strength, and open or closed cabinet construction. Three channels per speaker and eight microphone options per channel provide plenty of scope for exploring different textures, while room controls and a four-band EQ help refine the result. It suits home producers, guitarists, and bassists who want to customize familiar cabinet sounds or experiment with unusual configurations. Both the native plugin and an Amp Room version are included.
