The dynamics of the {\em generalized} CEV process $dX_t = aX_t^n dt+ bX_t^mdW_t$ $(gCEV)$ is due to an interplay of two feedback mechanisms:State-to-Drift and State-to-Diffusion, whose degrees are $n$ and $m$respectively. We particularly show that the gCEV, in which both feedbackmechanisms are {\sc positive}, i.e. $n,m>1$, admits a stationary probabilitydistribution $P$ provided that $n<2m-1$, which asymptotically decays as a powerlaw $P(x) \sim \frac{1}{x^\mu}$ with tail exponent $\mu = 2m > 2$. Furthermorethe power spectral density obeys $S(f) \sim \frac{1}{f^\beta}$, where $\beta =2 - \:\frac{1+\epsilon}{2(m-1)}$, $\epsilon>0$. Bursting behavior of the gCEVis investigated numerically. Burst intensity $S$ and burst duration $T$ areshown to be related by $S\sim T^2$.
