This is the new generation Sound FX Box -- hand made in Japan for Deadly Dragon Sound. This one expands upon our base model with the added feature of built in delay, volume and a pitch knob. As with our other model -- this is a TONAL MODULATOR which means that this is an analog sound creator, not a sampler. It is the perfect tool to give your dance an extra flavor of barely contained chaotic FUN! *** note: due to varying country specifications we do no supply a power adapter with the unit. please use a 7.5V AC 110mma adapter w/ a plug that meets your country's specs. radio shack sells them here for $10 - $20.
