Here is an Ibanez SB7 bass synthesizer pedal. There are 3 modes in this pedal that will give you a wide range of sounds, ranging from autowah, to crazy synth sounds.

• Auto Wah Mode

• A touch-sensitive envelope filter effect that reacts to your playing dynamics.
• Great for funky bass lines, slap playing, and classic auto-wah sounds.
• Frequency knob: Adjusts the range of the filter sweep. Lower settings sound thicker and darker, while higher settings create brighter, quackier wah tones.
• Resonance knob: Controls the intensity and sharpness of the filter peak. Lower settings are smoother and more subtle; higher settings produce a more dramatic, vocal-style wah effect.

• Synth 1 Mode

• Produces a smooth, deep synth-style bass tone with a warm analog character.
• Excellent for fat sustained notes and classic electronic bass textures.
• Frequency knob: Shapes the brightness of the synth voice. Lower settings emphasize deep lows and warmth, while higher settings add clarity and edge.
• Resonance knob: Increases the prominence of the filter sweep. Higher resonance settings create more pronounced synth movement and a sharper attack.

• Synth 2 Mode

• A brighter, more aggressive synth sound with a sharper and more modern character.
• Great for cutting lead-style bass synth tones and experimental textures.
• Frequency knob: Controls how bright and forward the synth tone becomes in the mix.
• Resonance knob: Adds intensity and bite to the filter effect, ranging from subtle shaping to dramatic, vocal-like synth peaks.

The SB7 is highly responsive to playing dynamics and can cover everything from subtle filter textures to wild synth effects.

This example of the pedal has been used well. It functions 100%, and the footswitch works without issue. You'll see in the pictures a good amount of cosmetic defects, scuffs, scratches etc.
