In contrast to his Hofner bass, the Rickenbacker was a larger and heaver bass guitar. It's solid body weighed in at ten pounds and its maple and rosewood neck at 33 1/4" was much longer that the Hofner at 30". The longer through body neck and solid form gave the Rickenbacker a deeper more elastic tone and a more complex resonance than the Hofner, which according to McCartney also had a hard time staying in tune. The bass was fitted with a pair of robust 'toaster top' pick ups, one covered with a large chrome hand rest.When McCartney received the instrument it was decorated in a sharp 'fireglo' finish and featured two regal horns that protruded from the top and bottom of the instrument, in addition to volume and tone knobs for each of the pick ups respectively.
As the Beatles touring days came to a conclusion and their radical studio explorations drew closer, the Rickenbacker became McCartney's go to instrument for his increasingly revolutionary melodic approaches. The switch to this aforementioned instrument coincided with McCartney's discovery of the magic of counter melodies and a new guitar players approach to the instrument. These factors should be taken into account with McCartney's new found experimentation with the avant garde as well as with drugs, as this new bass provided the perfect platform for the Beatles arising musical directions beginning in 1965.
The 4001 bass was now a permanent fixture in McCartney's arsenal. In 1967 the Rickenbacker locked down the bottom end on the Sgt Pepper's Lonely Hearts Club Band LP as well as featuring the Beatles singles during this era. 'Penny Lane' and 'Lovely Rita' are fine examples of the timbre of this instrument in action, as well as McCartney's multifaceted and influential approach. The bass got a facelift in 1967 when Paul had it psychedelically painted in addition to a few of the other Beatles instruments undertaking this change. A nice representation of the 4001 on video with its acquired paint job is on the available 'All You Need Is Love' broadcast footage, the 'Hello Goodbye' music video and the 'I Am the Walrus' performance from the Magical Mystery Tour film.
Post-beatles it would figure heavily in the multitude of buoyant bass lines comprising the 1970 solo LP McCartney, the 1971 album Ram and the 1973 'Wings' album, Red Rose Speedway. While never becoming his 'main' instrument, it appears that when ever McCartney required a hearty tone with a chunky and cutting attack he would return to the 'Ric'. The 4001 slowly became identifiable with McCartney, as it did become his preferred on stage bass.
McCartney's Rickenbacker 4001 bass is still working today, Giles Martin, producer on McCartney's 2013 album New revealed that the bass was used during the making of the LP on one track. The 'rock room' has not been able to confirm or deny this track as of yet. The bass has been McCartney's trusted companion for 50 years, never completely replacing the iconic Hofner in the eyes of fans, but always on a rack waiting for its moment to sing. Rickenbacker's have a discernible sound popularized in the 60's and still disseminated today. Combining this sound with the artistic prowess and revolutionary thinking of Paul McCartney equatedto the documented musical success. From its beginnings and creation in the ambiance of creativity of the 1960's, McCartney's Rickenbacker bass has now become inseparable from McCartney himself in the annals of rock history.
