Based on inspirations of the Handwired EF86 Tube preamps from the early 90's!
The heart of this preamp is a EF86 (6267) Valve running at High Voltage. Ever wanted to get the crystal clear crunch of the classic EF86 Tube Preamps - This is IT!
The DC-30 is a two-stage switchable design allowing it to switch from a clean channel to a dirty channel with independent gain and volume settings. 
Each DC-30 is hand-built, hand-wired, and tested one at a time.
