The SC-101 bridge has 11.5k DC resistance and 3.6k henries inductance. The output voltage of all of those pickups is about the same. I've compared outputs of types of pickups here The SC-101 and SSL-1 both use AlNiCo 5 pole pieces, and except for the bridge pickup, all are around 6.5k to 7k ohms DC resistance. But the output level is easy to infer based on the structure of the pickup and electrical values of the pickup.

The output level is dependent on the input level, and I'm sorry to say that it's no consistent between tests. Magnets are tested with a Spin Doctor ER The capacitance value is derived from the inductance and measured resonant peak. The inductance and Q measurements are made with an Extech 380193 in 'SER' series mode, and the mean value between the 1kHz and 120Hz modes is recorded. I measured the probes' capacitance at 20pF, so that amount is subtracted from the capacitance calculation. The pickup is connected to an integrator circuit, designed by Ken Willmott, with a Velleman 10x probe, and fed back into the Velleman PCSGU250. With load, 283K R and 540pF C across each pickup:īode plots are made with a Velleman PCSGU250 and the supplied probes in 10x mode, with the function generator feeding a driver coil of 0.48mH, placed on top of the pickup and driven with 2Vpp. My suspicion is that their wind counts are very close, with the differences owing to the magnet wire, perhaps the insulation thickness is thinner with the SSL-1's wire, causing the higher capacitive coupling within the coil.įrequency response bode plot, without load: The lower resonant peak relative to the Blackfaces owes to a higher parasitic capacitance, as the inductance values are all within 150mH of each other. The only other 'vintage output' pickup I've gathered as much information on so far is the GFS Boston Blues, and the frequency and inductance figures of the SSL-1 set puts it a lot closer to the Lollar Blackface set. The pole pieces are fully charged ALNiCo 5. This is supposed to be three of the same pickup with an RW/RP middle, so the variances are presumably unintentional. A bit harsh, maybe, unless I work the tone knob a bit.

Most of the pickups on the market with a 6.5K and higher DC resistance are said to be 'hot', but I've never thought of these as sounding hot or 'full'. History is written by the victors, maybe some lesser known predecessor has long since been forgotten. The history of the SSL-1 is well known, perhaps the first 'vintage Strat single coil replacement' to hit the market in the late 70's.
