What moves the price

Sold-listing reading: fair $2,653, good $3,351, excellent $3,910 USD · 9 sold listings · as of 2026-10-14. some lots are the AC30 'head' (amp unit) format rather than the combo - both are complete amplifiers and are kept together here, but a head alone sells below a combo, so treat the low end as head-format. AC-30/4 (1960-61) belongs to row vox-ac30-4-twin, Celestion Blue speaker lots / transformers / footswitch / chassis are parts, one early 'Copper Haddon' lot was too ambiguous to place. Reverb exposes the price and condition but not the exact sale date, so asof = measurement date; no good-condition sale observed; good = sample median
