Sadowsky's drop in preamp is perfect for adding that Sadowsky sound to J-style basses with a plate. The potentiometers can also be removed from the plate for rear installation for basses with a control cavity.
This preamp is a completely prewired system offering the same controls and preamp as all Sadowsky Basses: vol, pan, bass boost, treble boost, and vintage tone control (see below). The preamp can be installed with the included control plate or mounted through a rear control cavity in either a 4 in line or diamond pattern. Installation requires a side jack and a battery compartment.
What is a VTC (Vintage Tone Control)?: “It works just like a standard Fender® tone control. It is a passive control in which 10 is flat and as you roll it down it knocks off a broad swath of high end to give you a warmer tone. Although the control is passive, it functions with the bass in either active or passive mode. A little rolled off knocks off a lot of string noise. All the way rolled off, it gives you a lot of that "motown/flatwound" sound.” — Roger Sadowsky
