All-tube bass preamp

Porn Bass Pedal

from €490

The all-tube Porn Bass preamp in pedal form — 2× 12AX7 run on high voltage, the exact circuit of the single-channel 200W head. Piano cleans to vintage overdrive.

02 · Overdrive RTS boost / OD
Real Tube Screamer

RTS boost / OD

from €295

A high-voltage tube OD/boost with an internal charge pump feeding the 12AX7 at 200 VDC from a standard supply. RTS = Real Tube Screamer — midrange growl and output to push any rock amp into tight modern territory.

1× 12AX7 fed at 200 VDC (internal charge pump)

03 · Boost K Booster
20+ dB of clean boost

K Booster

from €150

All Wima film/foil caps in the signal path, through-hole components, and the 1044 charge pump maxed to 46 VDC internally — so it's safe to say it has 20+ dB of boost. Tighten your low end, get liquid solos, or drive a power amp.
