Sadowsky Bass Preamp

Started by Roger Sadowsky in 1979, the company started out by installing active preamp systems into Fender bass guitars. They then branched out to make their own live of bass guitars with active electronics, and were used by popular bassists like Marcus Miller, Jason Newsted, Tal Wilkenfeld, Brian Marshall and many more. They soon started making the Sadowsky Bass Preamp DI pedal, which is essentially a pedal version of the actual active electronics that they put inside their instruments.

This pedal is as straightforward as it gets with just three knobs that let you adjust volume, treble and bass. There's no fancy overdrive and advanced EQ effect, rather it is simply meant to improve the quality and signal-to-noise ratio of your bass guitar sound.

Other features include an XLR out for going straight to PA/Mixing Console, a Tuner Out, and a dedicated Mute footswitch.

Here's what I found by analyzing customer and expert reviews:



Most of its positive reviews commend the Sadowsky Preamp's sound and build quality. Most users recommend it for use with vintage bass guitars but it has also been used on other models with satisfactory results. It's transparent and easy operation were also mentioned as its advantage over the usual feature packed preamps.


Considering its limited features, the price is a bit steep for some users. Other than that, there aren't any notable complaints.


If you're looking for that Sadowsky tone as used by popular bassists, without having to modify your instrument, then get this preamp.
