Blackface Bassman — by this point widely used as a guitar head rather than a bass amp.
Marks that can be entered for this maker: Serial number (plate), Tube chart sticker, Transformer code, Speaker code, Pot code, Chassis stamp, Circuit code.
Nothing predates 1964; components only push the date later.
Sold-listing reading: fair $816, good $1,685, excellent $2,578 USD · 9 sold listings · as of 2026-10-14. heads and head+2x12 piggyback sets count as whole amps (that is how Bassman sells), cabinets alone do not. CATALOG GAP: the blonde/Tuxedo 6G6-B Bassman (1963-64) appears in the same search but has NO model row in models.json, so those lots were excluded rather than mixed into the Blackface row - the owner may want a row for it. Drip-edge/Silverface 1968-69 lots were routed to fender-bassman-sf; one listing ('1968 chassis 1965 Head Cab') is a parts build and was dropped; the last two lots in the same page are transformers (alignment verified only up to index 23, parts anyway). Reverb exposes the price and condition but not the exact sale date, so asof = measurement date; no Fair/Poor sale observed; fair = lowest sold price in sample
