Injectr is a fully-equipped electric guitar and bass interface for eurorack synthesizers. The module features an overdrive-capable preamp, versatile amp simulator, and control voltage extractors designed to inject stringed instrument signals directly into the modular environment. Injectr’s high-impedance instrument input, INST IN, feeds straight into a variable gain circuit which can produce a range of tonal responses, from clean to heavily overdriven. The smooth character of the DRIVE parameter is made possible by a soft-clipping topology using a classic 4558 op amp and four diodes, two silicon and two germanium. A post-drive LEVEL control is provided to trim the output of the preamp stage, which is accompanied by a RED LED, indicating that the signal is reaching the typical eurorack audio level of 10 Vpp. Because stringed instruments tend to have strong transients, it is suggested to adjust the LEVEL control so that the LED is illuminated with moderate to heavy playing. One of Injectr’s most useful features is the Amp Simulator circuit. Using a complex arrangement of analog filters, it imparts an amplifier-like quality to the signal. The CHARACTER parameter alone can dramatically alter the sound, giving the user combined control over the middle “dip” frequency and bandwidth. The PRESENCE parameter adjusts the low-end response, thickening or thinning the overall tone, whereas the BRIGHT switch enhances high frequencies. In combination with pickup selection and tone controls of the guitar itself, these parameters provide a wide range of tones all while staying within the eurorack system. If preferred, the Amp Simulator can also be toggled off by disengaging the SIM ON switch. The module is equipped with a eurorack-level effects loop, FX SND and FX RTN, serving as an access point to process the signal after the Preamp/Drive circuit but before the Amp Simulator. It is also useful to process the signal with eurorack modules before taking the signal back out using the Line Out. High-gain modules such as overdrive/distortion and intense compression may cause unwanted feedback in the FX Loop, and so are best patched after Injectr from the OUT jack.
