For sale is a Noll TCM3PM onboard preamp.
$120 shipped. PayPal only. SOLD!
It is an insane 9v 3-band preamp with sweepable mids. This preamp is extremely high-quality and it's made in Germany. These preamps are used only in the highest-grade basses such as Ritter. I would gladly keep it but, sadly, it doesn't fit in my bass's preamp cavity.
The preamp comes completely prewired, works just fine with no issues, and works with both active and passive pickups.
