They've been around for quite some time.
Michael is a real thinker - check out his guitar amps like the REVELATION, and MEGALITH.
Simply amazing what he has done for such a small outfit, considering how small the aussie made scene is, (compared to the USA boutique builders) and considering he's taking on some massive competition from cheap imports from the USA, China etc.
I've had three of his pedal's.
GI FUZZ (silicon high gain)
Blue Boy Deluxe
Blue Boy Pro.
Let me say first - his pedals are EQ'd for guitar.
So bear that in mind when you dial up the bass knob, you'll be turning up low mids.... Anyway!
His sense of EQ is unlike a Leo Fender however, as Michael tends to like a more bassy tone.
The GI Fuzz is an awesome fuzz for velcro ripping, colon evacuating, silicon look at me look at me look at me.
But it does suffer an (admittedly) small amount of low end loss if you play down to B.
In a blender (with inversion switch) I found this an incredibly versatile fuzz.
The Blue Boy Pro is kind of in the same box - very good at what it does, but it does lose a small amount of lows. Many of you may not notice it tho. Fuzz switch was fun.
I traded it for the BBD.
Same basic tones as BBD but lacks some of the more bass friendly tones.
BBD is the ducks nuts.
Great OD. Supposedly a tweaked TS-like circuit, but I wouldn't know.
Can be tweaked for massive lows, light to heavy - even farty OD. Very versatile. Can sound a bit compressed at higher gain settings, but then - what drive pedal doesn't?
I really liked the BBD - great pedal.
