A-199 Spring Reverb Module : Dark, muddy and brooding

The a199 has a lovely dark spring sound, the provided spring tank is a great match and starting point for a collection of tanks. Spring reverb is not the clean realistic sound associated with reverbs today - its clangorous, shonky and unmistakably mechanical in nature. The A199 is slightly l less feature filled than some other spring reverb modules available (no vc of feedback amount or wet/dry mix, no tank selection etc - all easily patchable though) - but a fraction of the cost. Follow the mounting instructions carefully to avoid unwanted artifacts (they are very susceptible to interference) - I've opted for keeping the tanks out of the case. You may consider also buying a decent external phono switch so you can have multiple tanks linked to the unit at once - saves popping the module out to change tanks.

I love playing with the feedback path of the a199 - it can even play self patched, great for drones... A typical drone patch for me would go:

A199 with no audio being fed to it, high feedback -> feedback insert goes to a vca -> A189-1 bit mangler -> Freqshifter -> A106-5 sem filter -> feedback return of the A199. Modulate away on the modules in the feedback path and the results are stunning - so organic, dark and ethereal.

I also like using it to add body to drum sounds or synthesised pianos, keep feedback low and run the mix output to a vca to shape the level contour.
