The Geiger Counter Pro (GCPro) is super awesome. Period! I just bought the pedal used from Prymaxe for a big discount & love it & wanted to share so maybe someone else can benefit. To my ears it seems to do everything (have had it for a couple weeks & have already found these sounds listed here): just about all 1950s/60s/70s/etc type fuzz, 80s arcade blip fuzz, octave fuzz, brass/horn fuzz, smooth fuzz, splattery fuzz, radio fuzz, overdrive, treble boost, distortion (light to the heaviest), ring mod, etc. I'm selling my Fat Fuzz Factory & potentially several other pedals because the GCPro is: 1) super-versatile, 2) easy-peasy to dial in (99% of everything I dial in seems to sound awesome - this is what I hated with the Fat Fuzz Factory), 3) is stage ready & saves 16 presets available via the "UP TO NEXT PRESET" or the "DOWN TO PREVIOUS PRESET" foot buttons, 4) has a vst/midi plugin which I easily setup with my reaper daw (the plugin controls everything on the pedal except for maybe the master volume & such), 5) has a wet/dry mix, 6) has an analog/digital mix, 7) has a filter, 8) is super-small for everything it does, and 9) is well-built. I'd been searching for such a pedal like the GCPro for about 4 years, and originally wanted a Paul Trombetta pedal, however I think he got super busy & never called me up after I added my name to the super long wait list. I have 3 Basic Audio pedals & the Blackout Effectors Special Twosome Deluxe, all of which are simply awesome & versatile pedals, however for me they're not as versatile as the GCPro (it'll break my heart to get rid of them if I ever decide to do that). I've also looked at Death By Audio pedals, bought FuzzHugger's Phantom Arcade, and tried others, but still couldn't find the magic I was looking for. (I am in no way affiliated with WMD) Cheers!
