This playlist demos the budget Squier Vintage Modified Jazz Bass 70. I believe it's one of the first series, they had Duncan designed pickups. 
I tried several pickups just for fun plus the Aguilar OBP-2 preamp.

The tracks are set in the order of the manual.
The Bass is a 5 string Czech SSD NS-5CR loaded with EMG DCs. While the treble is nearly fully boosted the bass and mid controls are boosted slightly.

LHZ MID-04 Control

Spector Euro 4LX TW, pickups changed to P4 and J (reversed coil), Spector 18V HAZLab Pre, DR DDT Strings (45-105), bass and treble boosted to 100%

Spector Euro 4LX, 18V HAZ, EMG P4-J(r) Boost

This playlist showcases the Spector Tonepump preamp (also know as Michalik BP-4) in a Spector Euro 4LX. The Spector's originally a TW model, the pickups have been replaced with 35P4 and 35J-R and is strung with DR DDT string 45-105. Wiring is done vol/vol/pre/out.

When boosted, bass and treble are always boosted to 100%. entered means bass and treble controls are set in center. As there's no real center detent for the pots and the Tonepump works in non-linear fashion in terms of dB I just set them manually to center.

Hi,
On this profile you’ll find sound samples mainly from Spectors but also from other basses I have - current and past. 
The demos also focus on different pickups and preamps which I did try out. Hazlabs, EMG, Aguilar, Tonepump, Darkglass, SNC and BazCustom. Everything's mine, just doing it for fun.
