This yellow fasel is a Toroidal design with the tonal character of a cup core, best for attaining a vintage vibe. Use the precision-wound Toroidal, part number P-ECB-FI-02, for the cleanest sound possible. The Fasel inductor is back! These near-mythical inductors are the key to the singing tonal sweep every wah player lusts for but can't capture with a new pedal. The ultimate upgrade to your current wah, these magic bullets are available exclusively from Dunlop, the new worldwide agent for Fasel of Italy. Your wah will finally give up the lush harmonic sparkle you've always heard in your head but could never coax from your rig.

The AS394CH is a junction isolated ultra well-matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pairs. Electrical characteristics of these devices such as drift versus initial offset voltage, noise, and the exponential relationship of base-emitter voltage to collector current closely approach those of a theoretical transistor. Extrinsic base and emitter resistances are very low, giving very low noise and operating over a wide current range. To guarantee long term stability of matching parameters, internal clamp diodes have been added across the emitter-base junction of each transistor. These prevent degradation due to reverse biased emitter current, the most common cause of field failures in matched devices.

LM318 single op amp in an 8-pin DIP package. The LM318 is a precision, fast operational amplifier designed for applications requiring wide bandwidth and high slew rate. They feature a factor-of-ten increase in speed over general-purpose devices without sacrificing dc performance. These operational amplifiers have internal unity-gain frequency compensation. This considerably simplifies their application because no external components are necessary for operation. However, unlike most internally compensated amplifiers, external frequency compensation may be added for optimum performance. For inverting applications, feed-forward compensation boosts the slew rate to over 150 V/µs and almost double the bandwidth. Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed. Further, a single capacitor can be added to reduce the settling time for 0.1% error band to under 1 µs.
