LEGENDARY, CUSTOMIZED BASS BOOST
BUILT FOR YOU
We hand assemble each cMoyBB and tweak output power and bass boost for your equipment. Simply specify your headphones during checkout.
FEATURES OF THE CMOYBB V2.03
cMoyBB is the most fully featured cMoy made.
JDS Labs's success is due to cMoyBB's legendary bass boost switch. Switched off, your original audio signal is amplified. Switched on, bass increases up to 9.4 dB for a perceived 2x increase in bass volume.
PRINTED CIRCUIT BOARD (PCB)
Older cMoys use thin wires or protoboard to transfer audio signals. cMoyBB uses a carefully designed PCB with attention to detail that cannot be achieved in protoboard amplifiers, or even in circuit boards designed by experienced hobbyists.
cMoyBB handles more than twice the voltage of most cMoys and supports dual rail splitters. The result is over 200% higher power handling than the original cMoy! Decoupling capacitors on all power pins significantly enhance opamp stability and sound quality.
POWER INPUT JACK
cMoyBB's power input jack allows you to power the amp from your desk. Optional charging support also provides convenient, integrated 9V NiMH battery charging.
cMoyBB is cased inside of a brand new Altoids ® Peppermint tin, protecting the circuit from some forms of external EMI / RF interference. You may choose between two tin styles: Peppermint or Wintergreen.
Specify your headphones during checkout and we'll optimize gain, bass boost, and output power for best performance with your headphones. A techincal summary ships with each custom cMoyBB.

Gain 6x (or Custom) Volume Potentiometer Taper 3B
Case Dimensions 116 x 64 x 21 mm Weight 3.6 oz
Standard, 1x9V: Best for most users. External DC jack can be used to power the amplifier. Does not charge battery.
Standard, 2x9V: Recommended for high volume listening with 120+ ohm headphones. Does not charge batteries. Battery run time is identical to the 1x9V edition. Higher voltage enables higher volumes for high impedance headphones
Rechargeable, 1x9: Ideal for portable use of most headphones. Adds integrated charging circuitry and includes 1x9V Tenergy low self-discharge NiMH battery. Requires a 10V+ AC/DC adapter (not included)!
