I moved the Bluebeard to the guitar board, and yeah, it totally slays with the skinny strings.
I'm pushing it into a Fullbore Metal and the harmonic screaminess is ludicrous! By itself it is a great mid/high-gain distortion. I sold the Megalith Delta the day I sampled the Bluebeard on guitar. This works great since my gf has wanted a muffled fuzz and high gain distortion on her board. Best of both worlds in one box!
On bass it was redundant with my set up, since I have a high frequency gated fuzz and a low frequency muffled fuzz parallel blended together. UBER FUZZ!!
Plus, my gf loves Prince Voltan from Flash Gordon (1980), whom I etched into the pedal. Stepping on this effect she channels his insanse ferocity and battle glee.
