Description

Dunlop produced the 105Q-U Cry Baby Bass Wah as a wah pedal engineered specifically for bass guitar, optimising its filter circuitry to preserve the low-end fundamental that standard wah designs can attenuate or lose. It sat in the Cry Baby line as a bass-dedicated variant, distinguished by its auto-return switching and a frequency sweep calibrated for lower-register instruments, with a filter centre frequency that travels from 180 Hz at heel-down to 1800 Hz at toe-down.

The 105Q-U operates on a 9-volt DC supply at a draw of 3.5 mA, making it compatible with standard pedalboard power arrangements. Input impedance is rated at 1 MΩ and output impedance at 1 kΩ. Gain at the filter centre frequency rises from +25 dB in the heel-down position to +32 dB toe-down. The pedal uses a buffered bypass circuit. Auto-return switching meant the effect disengaged automatically when the player's foot left the pedal, without requiring a deliberate click.

Owners sourcing a replacement power supply should confirm a regulated 9-volt DC centre-negative output at or above 3.5 mA. For wiring, calibration, or internal servicing questions, a qualified guitar technician will be best placed to advise.

From the people who own them

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

Put yours on the record.

The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.

What do you know about this one?

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
