Where they differ · voice
Same Celestion family, opposite voicings. The Greenback is mid-loaded with a broad upper-mid peak that reads vocal; the Vintage 30 is forward with a narrow peak and presence above. The Greenback's peak is what people mean by Plexi; the V30's is what they mean by modern Marshall.
