The BYOC E.S.V. 2-Knob Bender is quite possibly the sweetest MKII Professional Tonebender clone you can get. What makes the BYOC E.S.V. 2-Knob Bender so "extra special"? BYOC started with a redesign of the PCB so that it would fit the larger axial leaded capacitors and carbon comp resistors and made the layout look nice and pretty. They wanted the E.S.V. series to be aesthetically appealing on the inside (the outside is up to you!). They also made the solder pads and traces as beefy as possible. Thicker traces mean better signal flow. It also makes the PCB virtually indestructible and makes soldering a breeze. The next thing that makes the BYOC E.S.V. 2-Knob Bender special is the component selection. They used the highest quality and coolest looking vintage mojo parts they could muster up - carbon comp resistors, shiny blue Vishay aluminum electrolytics, and axial leaded film capacitors. But the heart and soul of any Tonebender is its transistors. The BYOC E.S.V. 2-Knob Bender kit comes with a set of N.O.S. Philips OC76 germanium transistors that have been tested for leakage and gain selected to produce the best tone.
