My bass got stolen, so it was replaced with a Guild hollow body (Guilda). I also bought a Fender 6-string bass like Jack Bruce had. In 68 I needed more power so I added two Kustom cabinets with 3 15"s total of 6 speakers. I kept my K-100 brain. About mid 69 I replaced the 6 15"s with Lansing Speakers (sweet).
I quit rock for a short period and played in a popular music band. Downgraded back to 2-2x15 lansing Kustom cabinets. I bought the Gibson EB3 (walnut) with this rig.(Bass on right shown with Kustom amp above.)
I went back to rock and bought a super rig. An Acoustic 360 hooked in series with a Sunn 2000s. You could hear and feel me for blocks playing at Lee Park in Dallas at outdoor concerts. I started playing a Fender Telecaster bass (Terry).
The band broke up so I let the Acoustic go back and kept the Sunn. Not a good choice looking back on it. Went back into popular showband circuit. I eventually Traded in the Sunn for a Marshall Bass rig. I traded the Telecaster bass for a Ampeg Dan Armstrong (clear) bass. Sexy! yeah baby!
I sold the Marshall and yes went back to the Acoustic 360. The Ampeg & Acoustic was the rig I played in Blackbird with Stevie Ray Vaughan.
I traded in the Ampeg on a new 1972 Fender Precision (Precsilla) that I still have to this day. Absolutely the best bass I've ever played.
