The Spring Tanker, a compact Spring Reverb Tank combined with Voltage Controlled elements, further extends the processing dimensions of the current red BugBrand designs. The Electro-Mechanical process massages any audio it is fed – the springs are exposed for (gentle) mechanical disturbance and the VC parameters of Amp and Filter tie the machine into your analogue studio flow.
Have a look at the Block Diagram image [linked here] to see the internal signal flow. An Input Preamp with gain brings the mono signal input up to suitable internal levels before the signal splits to the Output Mixer (Dry) and the Reverb Drive VCA (Voltage Controlled Amplifier).
This Linear VCA sets the level feeding into the Reverb Core and can be controlled by the Level dial combined with Control Voltage (CV) Modulation from the Polarising Depth control. A Feedback path, again VCA controlled, takes the Reverb output (normalised) and sums it back in to the input of the Reverb Core (do treat this path with care – it can scream!). Of course, an external processor can be inserted within this feedback loop via the Send (Reverb) / Return (Feedback) sockets.
