Description

Ibanez produced the BIGMINI as a compact chromatic tuner pedal designed to occupy minimal space on a pedalboard. It sat in Ibanez's effects line as a utility pedal aimed at players who needed accurate pitch detection without sacrificing board real estate.

The BIGMINI offered two tuning modes — needle mode and strobe mode — and an LED display rated for readability in low-light stage conditions. Its tuning range of A0 (27.50 Hz) to C8 (4186 Hz) covered instruments beyond standard six-string guitar, including the low B string of a five-string bass. Flat tuning was available in steps of one, two, three, or four semitones down, and the A4 calibration reference was adjustable between 435 Hz and 445 Hz. The unit ran on an external DC 9V adapter with negative centre pin and drew 14 mA. Signal routing used a true bypass switch, keeping the signal path as direct as possible when the pedal was disengaged.

Owners tracing compatible DC power supplies should confirm the negative centre pin polarity and 9V rating against their power brick specifications; a qualified guitar technician can assist with pedalboard power planning or any wiring concerns.

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.

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.
