Breda Audio Music Man Stingray Pre-Ernie Ball 1978 Inspired Onboard Preamp

This is an onboard preamp for electric bass inspired by Music Man Stingray pre Ernie Ball from 1978. 

It's not a 1:1 clone since it has been chosen a modern approach with the prerogative of maintain the original sound of the time.

The differences are:

• anti-inversion diode in order to protect the IC in case of a reverse polarity
• resistor that minimize the "bump" when the preamp is bypassed and engaged (naturally you can wire up the classic A25K volume after the OUT of the preamp itself) 
• added the 1KOhm resistor in order to protect the IC, this was a feature introduced in the 1982
• a better power supply section

The limited dimensions of 43mm x 19.5mm allow the fitting of this preamp in virtually any kind of bass.

The frequency response of this preamp was studied in order to have a distinguishable sound rather than a flat color.

The bands frequencies are:

• +20dB / -16dB @10 kHz for the treble
• +14dB / -7dB @40Hz for the bass

The preamp will be provided with 2 separate pots (one for each band) whose measures are M8, 10mm threaded part and center click.

Thanks to these dimensions you can put everything on a pickguard/plate or directly onto the wood of the bass.

It's true that generally there isn't any center detent on the pots in this kind of preamp but, since it's a boost-cut preamp, i find it a very logical and handy feature. In particular the values of these 2 custom pots are:

• C1M for the treble
• A100K for the bass

22 awg silicone wire.

Every product is tested before shipping and i will ensure a clear and complete communication!
