It MSRP's for around $230, sells for $130 and I got it for $40 in my local music shop.
The boost: it's really amazing. It's a great boost, and adds up to 20dbs. That's a lot of dbs just hangin' around on tap. Great clean boost, but adds a little dirt on higher volumes.
The overdrive: When I got it, I was **bleep** off. It sounded sterile, raspy and pretty much unusable, and for a pedal of this pedigree, it was unacceptable. I tried it on a friends Marshall and it really shines boosting up an already slightly overdriven sound. I play through a twin reverb. Not much OD going on there. I wouldn't use this as a standalone OD. I'm still on the lookout for one of those, but if you can find it for cheap, buy it.
