Finally, mode D on kick drums produces excellent results so long as you keep the cutoff low - push it much higher than 150Hz and you'll notice the upper harmonics. The All mode also works great with kicks, sounding like mode A with more edge.

We tried PEHz on other sounds, such as acoustic guitar, piano and sub-mixes, including stereo drums. The more complex the sound, the more we opted for subtle enhancement, and there were times (eg, with acoustic guitar) when we couldn't improve things.

PEHz can struggle with complex sustained sounds and success lies in choosing the right mode and dialling in the cutoff frequency. We were happier processing individual sounds, although we did have success bolstering low frequencies in a stereo mix.

Precision Enhancer Hz is a good effort and is the sort of processor you think you don't need… until you really need it! It's also DSP-friendly, giving 38 mono instances on a UAD 2 Solo, but UAD 1 owners might be irked that - unlike the rest of the Precision range – it's UAD 2-only.

Listen to our audio demo to hear:

1. Electric bass: In mode A, first bypass, then switch in effect solo and add 50% process, then sweep up filter from 16Hz to 320Hz. Switch out of solo. Then solo again and choose frequency. Now drive input more and bypass to compare a few times. Next the same process but in mode B.

2. Synth bass: In mode C with slope 36, bypass then switch in effect and sweep up in solo mode. Switch slope to 24, sweep down, switch slope to 12 sweep up then to 6 and sweep down. Now adjust effect, switch slope to 24 then 36 and re-adjust cut off point. Bypass to compare.

3. Kick drum: In mode D with slope 36 gradually increase effect to about 60% then reduce frequency to show effect. No switch between various slope options then bypass to compare. Increase effect level. Now switch to 'all' mode and adjust frequency. Bypass to compare.

4. Drum kit mix: Set slope to 24 and frequency at full, increase effect to 70% then switch through modes from A to D then 'all'. Reduce frequency for right effect then bypass to compare a few times. Now reduce frequency further and do the same again. Adjust levels and bypass to compare.
