Since we first introduced The Schaffer Replica: EX Tower bassists have been asking us to create a pedalboard-friendly stompbox tailored to bass frequencies. Well, you spoke and we listened! To our low end afficianados who have waited so patiently, we proudly introduce The Schaffer Replica: BASS-X.  

The BASS-X features a 100% analog signal path that is nearly identical to our famed EX Tower.  It perfectly captures our signature “Schaffer Sound” voicing and offers five interactive circuits capable of generating a plethora of tones for every bass configuration and genre of music. 

This interactive optical limiter+EQ expander+harmonic clipping circuit+boost+line buffer was reverse-engineered from the original Schaffer-Vega Diversity System wireless units used by nearly every legendary bassist throughout the 70s and 80s. Our modern reproduction of this circuit has quickly become the secret weapon for Pino Palladino, Billy Sheehan, Rudy Sarzo, and some of the most influential bassists today.


  • GAIN knob controls our signature clipping circuit that simultaneously bumps crucial low-mid frequencies responsible for adding punch and growl to the bass guitar. The harmonically rich effect produced by this frequency-enhancing gain circuit will open the door to the luscious bass tones heard on timeless recordings by Pink Floyd, The Eagles, Kiss, The Grateful Dead, Thin Lizzy, and the many other legends who originally used this vintage analog device. 
  • BOOST knob controls a powerful pre-amp capable of delivering a whopping 31db of clean boost. This analog boost is perfect for making lead parts stand out, adding fullness to the signal going into the front end of your amplifier, or pushing it into oblivion!
  • LIMITER knob controls Ken Schaffer’s signature Opto-Isolator limiter. This optical analog circuit naturally limits the audio signal going into the pedal's circuitry. Limiting is commonly used by mastering engineers to transparently raise overall level, without the risk of clipping and distortion generally associated with gain increases. Sensitivity of this effect may be fine tuned for different output pickups or to give your instrument a percussive or sustained attack.
