Yes and no. A blaster doesn't seem to boost any frequencies much. So, an EQ pedal with a good buffer placed really close to the guitar (very short cable run) will mostly do the job. The problem is even a 10 foot cable before the buffer will make a difference.
The other issue is the slight JFET distortion you can get from a pushed blaster is not going to be duplicated by an EQ pedal.
Personally, I prefer the buffer in the guitar, but not necessarily a blaster. There are better newer designs that don't pick up noise and just do their simple job better.
