"3 handmade analog drum boxes by Mr.AcidMachine.
Sorry about the poor sound quality from my camera.
Mrs.BassDrum is based on the TR-808 BassDrum with extra controls.
Mama Maraca is based on the TR-808 Maraca with extra controls.
Dr.Rimshot Clave is based on the TR-808 Rimshot/Clave.
Mrs.BassDrum and Mama Maraca sound pretty much the same as on the TR-808, while Dr.Rimshot Clave sounds a bit different, somewhere between the 808 and 909 Rimshot sounds, yet different and unique.
All 3 can be triggered by an external audio signal, drum pad, or voltage trigger.
All 3 can be powered by a 9 volt DC (negative center) adapter or a 9 volt battery. For sale on ebay tomorrow!! One day only!!"

"Up for auction are 3 handmade analog drum boxes by Mr.AcidMachine!! Mrs.Bassdrum, Mama Maraca, and Dr.Rimshot Clave are all included in this auction. All 3 are based on the Roland TR-808 drum sounds. Mrs.Bassdrum and Mama Maraca can make traditional TR-808 sounds plus more with the additional knobs, while Dr.Rimshot Clave sounds somewhere between the TR-808 and TR-909 RimShot and the Clave has a unique tone. Fully analog circuitry folks!! Play on the pads, plug in an external drum pad, a trigger out from a drum machine, or any audio signal to the IN jack to trigger the sound. Enjoy!!
