Here’s a vintage 1959 Fender Bassman 5F6-A electric bass guitar amplifier. This particular example, serial number BM01836, is in 100% all original condition, and displays serious vintage vibe, major mojo, and a prominently pronounced patina. While Wikipedia isnât always the best place for accurate info, we completely agree when the relevant article claims that this 5F6-A 4Ã10 configuration, “came to be one of the greatest and most sought after amplifiers in history.” This is the amp that inspired Jim Marshall to build his first amplifiers, and is widely considered one of the best 50 watt amplifiers of all time. Like many amps originally intended for bass, it has since become synonymous with, if not the epitome of, quintessential guitar tone, and this particular Bassman is a shining example of such.
Serial Number: BM01836
Tube Chart Date Stamp: ID (April 1959)
Transformer Codes: 8087, 45249
Speaker Codes: (2) 220902, (2) 220908
What this amp lacks in condition and cleanliness, it makes up for in raw tone. Famous for simple and stunning sound, with loud musical compression, Freddy Tavares created an undeniable masterpiece when he innovated upon the 5F6 to give birth to the ultimate 5F6-A. With approximately 4,000 produced over a 3-year period between ’58-’60, it would be a generous assumption to estimate that approximately half of the originals still remain in some semblance of intact original condition. And though this specimen displays fraying, snags, stains, fading, etc., it is still surprisingly all original. With the exception of a couple changed tubes, it is otherwise entirely 100% intact. With original transformers, original speakers, original capacitors, original hardware, and even the original gray power cable.
The amp works perfectly, and it sounds incredible. One speaker exhibits cone fatigue, and though it is over-powered by the 3 other highly functional speakers, it is still audible.
