This is the Professional DRV, another version of the 1981 Inventions DRV. Used only at home, there are no noticeable scratches or stains, but please note that this is a used item, so no returns or cancellations are accepted. Based on the original "DRV," this version uses clipping with NOS 1N34A germanium diodes, and the circuit configuration has been arranged accordingly. The sound is excellent, and the DeLorean graphic with the Flux Capacitor on the unpainted aluminum enclosure is also quite cool. This product is also scheduled to be listed on other sites. I will update it as soon as possible, but please understand that it may already be sold out due to the time difference. #1981inventions #drv #rat #overdrive #distortion #effector
