The only sure-fire way to date a Fender Bassman is by matching serial schemes.
Find the tube chart located in the back of your amplifier.
Hey there, I bought a Squier Affinity Strat last Dec.
and on checking the serial number I got this from Google.
Looking at serial numbers next to the ’60 5G5 brown Pro Amp for example, we see numbers ranging from 00001 to 02000, suggesting that there are 2000 of these amplifiers made in ’60.
Since several models can share one chassis type (for example, the early brown 5G7 Bandmaster, 5G5 Pro and 5G12 Concert), this kind of interpretation is inaccurate.
To this day, their violins are noted for their exceptional varnishes, and they command high prices as fine examples of early U. In the 1930s, Squier began making strings for the era's new electric instruments; the company also sold pianos, radios and phonograph records until divesting itself of all string-related products in 1961. Squier Company became an official original equipment manufacturer for Fender in 1963. By the mid-1970s, the Squier name was retired as the strings had taken the Fender name.
Fender Electric Instruments entered the picture in the 1950s, when the V. Squier Company began supplying Southern California inventor and businessman Leo Fender with strings for his unusual new electric guitars. Before the Fender Squier line of guitars was introduced in 1982, Fender was making lower priced guitars such as the Fender Lead series at its Fullerton, California plant.His work has been published on e How, Tech and in print for the "The Potrero View" and "Punk Planet." James is currently pursuing a Bachelor of Arts degree in journalism from Portland State University.Some things are very obvious such as non-original or reconed speakers, non-original transformers, replaced pots, re-tweed, re-tolex, re-grill, etc.The tube chart is a diagram detailing what kind of tubes are installed in your amplifier.It will usually be printed on a 4- by 4-inch sticker placed near the tubes in your amp. From 1953 to 1967, this was a two-letter stamp that corresponded with the month and year the amp was manufactured.Here are the serial number schemes from 1951 to 1970. 1951 - BM00001 to BM00550 1956 - BM00550 to BM01200 1957 - BM01200 to BM01600 1957 - BM00001 to BM00400 1958 - BM00400 to BM01500 1959 - BM01500 to BM03100 1960 - BM03100 to BM04600 1961 - BP00100 to BP01100 1962 - BP01100 to BP05000 1963 - BP05000 to BP08400 1964 - BP08400 to BP12000 1964 - A00100 to A03800 1965 - A03800 to A15000 1966 - A15000 to A33000 1967 - A32000 to A40000 1968 - A39000 to A49000 1969 - A48000 to A58000 1970 to 1983 - A58000 to A60000 The Bassman was discontinued in 1983 until Fender re-issued new versions of the 50s and 60s Fender Bassman models in 1990.
