From the vendor
Project overview
Inspired by Beetronics FatBEE, a fat overdrive circuit created in collaboration with the mythical pedal designer Howard Davis. Become the beekeeper of the fattest and sweetest buzzing overdrive sounds!
Introduction
Corpulent Bee mix the typical JFET overdrive natural and amp-like sounding with the fat and gurgling sounds of Beetronics pedals. The result is those unique sweet, smooth waves that you are going to love.
The basic tone is nearly transparent, except for a tender softening of the top end and a throaty thickening of the lower mids. Towards maximum gain, the drive doesn’t get that fuzzy but instead grows in warm, sweet, and stickiness, with very little ‘air’ but plenty of midrange bark to let choppy power chords cut through.
The tone knob acts essentially like an amp’s presence control, varying from extra spiky at the top of its range to smooth near the bottom.
Harvest the best tones with this buzzing board and get its unique, tasty sounds!
