No experience with that particular pedal but I can definately vouch for T-Rex pedals in general. I have a Mudhoney overdrive/fuzz pedal and a Comp Nova compressor. Both of which sound very good.
My only potential gripe is that the battery cover seems very flimsey and needs a flat headed screwdriver. It is a shame because the rest of the pedal seems very solidly put together.
The Mudhoney sound fantastic through an EL84 powered amplifier such as the Fender Blues Junior I use it with.
The MAB may be voiced slightly differentl but I would imagine it would be from the same ball park.
