OldComms emulates three pieces of vintage military or government audio equipment:
- an amplifier that offers 40dB gain with loads of tube distortion when pushed, plus a tone control to boost/cut the mids and a noise reduction control that allows for a little noise to be mixed in, for that extra vintage vibe,
- a tone control which is a single parametric EQ that can boost/cut the set frequency and which also has automatic shelving filters to boost/cut the high and low end,
- a Limiter/Compressor based on the rare but very popular Maxson/Dept of Commerce compressor.

We have attempted to emulate an authentic sound for these three modules which results in a warmer tone, with the lower bandwidth and extra dirtiness audio equipment had back in those days. This makes OldComms excellent for things such as (distorted) guitars and distorted vocals or some verygnarly (kick) drums.
