I sold my car and purchased this ‘75 Alembic S1 LSB in 1976, along with a carved student Kolstein upright.
Within a year, I had the frets removed at Fiddlers Music on Mack Ave in Detroit. Mainly, I was playing Jazz at the time, and figured that my intonation on the upright would help with the fretless bass guitar. which it did; but, the (non) ergonomics of Alembic design sorely tested that skill set. The frets stayed out for the next decade, and I gigged that as my only bass guitar during that time.
In 1987, and with a real job to support the family, I had the frets replaced at Elderly Instruments in Lansing; and at the time replaced my fretless needs with a Warmoth build, done by Brian Galloup at the Guitar Hospital in Big Rapids. Brian had also done a refin of my $275 trashed 62 Jazz, which I still play.
After three years gigging the Warmoth Jazz as House Bass at a Blues Open Mic Jam, I replaced that bass with a Pedulla Thunder Buzz ET5; which was a wonderful bass. Unfortunately, I lost track of that bass in flipping confusion trying to get a better upright. Whole nother thread about that bass, which has actually resold a couple times here on TB.
There were several others, MIM Jazz, Fernandez 5, an amazing Zon Sonus 4; but, all disappeared in the flip vortex.
Anyhow, around 2010, I acquired my current fretless, a mid 90’s Zon Sonus Special 5. After upgrading that bass to the Pope preamp, it has become my final fretless. It is close to 30 years old now; so, perhaps that qualifies as “yesteryear.” Anyhow, that’s where I landed. Fantastic instrument.
