Oddfellow Effects Caveman Drive

This looks kind of familiar.  Let me think about it .....  Oddfellow Effects Caveman Drive ...
No just can't remember, it will come to me.

OK I nicked that joke from Dr Boogey on FSB, and thanks to him for the trace.
One thing I must say is that in this vid it sounds a lot better than the OCD V4 that I used to own.

Info about the original:

The Caveman Drive is an extremely transparent overdrive that has an amazingly versatile range of sounds! This pedal nails every sound from full distorted tones to softer overdrive.The one thing about the caveman that amazes players is the dynamics. They are simply amazing. Not only is the caveman drive one of the best sounding drives on the market, it is the best feeling. The Caveman is one of very few pedals on the market that actually feels and reacts like a cranked tube amp. Go from screaming distortion to sweet, smooth, overdrive with no volume loss by simply lowering your guitar’s volume knob. Perfect for all styles of playing! The controls are volume, tone, drive and a brilliant fixed volume and gain boost which is just enough to give you that push for a solo.

DAM Meathead

Info about the original:

The Meathead. Often imitated, never surpassed. Little box, big idea. Caveman style fuzz tones for killing dinosaurs. Crank it up and hit that switch. Ka-pow! The flavour is thick and raw with a throaty woody bark. Optimum clarity and saturation are delivered with a long syrupy sustain at mountainous volumes. The bass to treble response is perfectly balanced for a heavy but dynamic fuzz tone that will project as well as it can saturate. A most excellently low background noise is achieved through careful transistor selection and biasing which further enforces the Meathead's fluid and articulate sonic capabilities.

Control

Just the one. Even through the Meathead has only one control different tones can be achieved. As the Dirt control is increased the signal not only becomes louder but slightly more saturated. Unity with your clean tone will be reached around noon thus giving you a great deal of volume boosting and drive capabilities. Lowering the guitars volume control will make the overall tone fizzier and increase the treble response.
Start out the Dirt control set at noon and increase or decrease as necessary. The greater headroom your amplifier has the greater the amount of volume boost the Meathead will deal out. The Meathead will also respond well to dirty or driven amplifiers. Used like this the Meathead will increase in intensity as the Dirt control is increased.
