DigiTech's PDS series Hot Box, a 2-in-1 twin pedal effects unit released in the 1980s. The left pedal is Delay Bypass ♾️Repeat, and the right is Distortion Bypass. Distortion can sometimes blend too much with the overall band sound or become too dry. In such cases, using delay can help the hard distortion mesh well within the band's performance, adding character to the lead tone that might have been buried (excerpt from a BOSS effects unit explanation). Delay times selectable are 16MSEC, 63MSEC, 250MSEC, 1SEC, and 1SEC/HOLD, with a 1-second looper function. Operation confirmed with a 9V battery, with no noise or crackling. A very rare "PDS2730 HOT BOX" from DigiTech's PDS series, in beautiful condition with the original box. Includes original box and manual. #distortion #delay #effectsunit #digitech
