After over 20 years of building basses I had become frustrated with preamps. Most are noisy, even without boost. And boosting treble comes with a loud hiss. Many pre’s don’t sound musical to me. There’s too much boost and consequently you can hardly use the whole sweep of the controls, and the boosted freq’s peak too much which makes it sound unnatural. The pre I was looking for didn’t exist, so I turned to Vanderkley Amps again. Together we designed the one and only pre that I am 100% happy with.
It features a bass and treble boost only, no cut. We limited the gain to 12db max @ 30Hz and 9db @ 8 kHz. You really don’t need any more. If you need to boost 20db, then perhaps it’s time for a better amp? This limitation allowed us to select better components than typically used and to design a better cirquit. The controls sound musical in whatever position. From subtly increasing bass and treble to full boost, it sounds natural and musical always. Go full boost for your Miller slapsound. And it is so silent, it raises the standard for preamps. The controls are: Vol (pull passive), Vol, Dual Tone, Bass, Treble.
