SPECTOR® USA 9-VOLT ACTIVE TONE CONTROL
CIRCUIT™
This is our famous classic
9v
USA™ active tone control circuit! We use these in our
USA
Neck-Thru NS-2™ bass, since the that 1970s. And the circuit
is still made by the same circuit guy! For use with EMG™
active pickups. This circuit fits our USA NS-2™ basses and
also our EuroLX basses. Please note that the EuroLX™ pot hole
routes may need to be widened a little to accommodate this
circuit's thicker pot shafts. Controls are master volume,
pickup balance, treble boost/cut, and bass boost/cut. Tone
Controls are +/-15db of gain. Includes the 9v circuit with
the pots attached and wired to it, and a wiring diagram.
Also includes a set of our NS-2 "IE2B" black plastic knobs. |
