The Herculean Deluxe combines two highly responsive drive circuits to deliver the most useful dirtbox sound possible, from clean boost to thick, amp-like gain. It's a combination of an updated version of the Herculean and Runestone overdrives. It offers a "D" style amp-like overdrive with a heavily tweaked classic Blues Breaker circuit. Both feature a variety of internal adjustments and order switchers on the face of the pedal to create the tone that perfectly suits your needs. Inside the Herculean Deluxe Overdrive is a 4-way dip switch that adjusts clipping on both sides of the unit. Select either or none at all to customize the pedal to your liking. The Runestone side offers both soft and hard clipping options, while the Herculean side offers a classic silicon soft-clipping feel or "Zen" clipping with MOSFET/NOS germanium diodes. An order toggle allows you to switch which circuit within the unit comes first. Combine this with the aforementioned clipping switch and you get the most sound ever packed into a single pedal enclosure.・9VDC power supply (center negative) True bypass switching Approximately 40mA current draw Mono input and output Housing dimensions: 4.705" L x 3.701" W x 1.657" H
