This Little Rat sounds exactly like a stock model. Nice and gritty with a light fuzz behind the distortion. But - half the size :) Also I've redesigned the look - added nice wooden panel, distorted by warms :) Plus added much better knobs (the original version has tiny knobs - not super comfortable and hard to see the positions). These mods can be easily removed, but trust me - it is much better like it is.
BTW, I am moving to plugins, so I sell almost all my physical pedals, see my other offers.
