WORKING CONDITION: Very Good. All pedals, faders, and buttons operate well and this CBP-1 tuned up perfectly using a Peterson Strobe Tuner. 

PHYSICAL CONDITION: Fair. There are several tears in the tolex, the metal control legend panel is severely bent, there is a small piece of wood missing from the lower part of the case, and the F# and G# keys have been replaced with crude wood blocks. However, the rest of the keys are sound, the plastic chassis cover is in good condition, and none of these blemishes affect the synth's performance or sound.

INVENTORY #59063

BRAND: Crumar 

MODEL: CPB-1

FUNCTION: Analog Synthesizer Bass Pedal Board

PRODUCT DESCRIPTION: This listing is for a Crumar CPB-1 Analog Synthesizer Bass Pedal Board. The Crumar CPB-1 is a rare, vintage analog bass synthesizer pedal board produced in Italy starting in 1975. Designed for gigging musicians—particularly solo performers needing "low end" accompaniment—it features a 13-note pedalboard played with the feet, similar to organ bass pedals. Unlike modern MIDI controllers, the CPB-1 is a self-contained analog synthesizer that generates its own sounds.

SPECS:

• Serial # A/721
• Keyboard: 13-note pedalboard (C to C).
• Architecture: Analog synthesis using a divide-down system based on frequency divider ICs (like the SAJ110 or S50240).
• Oscillator Options: Features 8' and 16' pitch switches (sometimes referred to as 16' and 32' in variations) to change the octave depth of the "pipes" or signal.
• Controls: Essential hands-free (or foot-operated) controls include:
  • Volume: Often adjusted via an oversized wheel or knob.
  • Sustain: Controls the length of the note after the pedal is released.
  • Master Tune: A pitch control typically found on the back or side of the unit.
• Form Factor: Housed in a rugged, portable Tolex-covered suitcase design with a handle for easy transport.
• Outputs: Features a standard 1/4" mono output that can plug directly into an amplifier or powered speaker.
• Performance Note: The unit has no MIDI or CV/Gate capabilities, making it a strictly standalone instrument unless modified.
• Sound Profile: Known for a thick, "killer" analog bass tone that pair exceptionally well with external effects pedals for added grit or modulation.

ACCESSORIES INCLUDED: Includes power cable.
