which amp do you recommend for distorted blues tones, some amps are too harsh especially in the upper registers when it comes to wide bends a-la Albert King etc. I have a Fender super-sonic and its way too ice-picky...its not musical enough...would the stray cat 30 or one of the overtone specials suit. I want it to chime in a musical way...it has to take pedals well...I dont mind if the model needs a overdrive pedal to get it to the required tone but its got to have that musical clean sustain we all look for.   

Sustain?

Any of the OTS models. 

They have that singing, overdrive and compression Lowell George and Bonnie Raitt used for overdriven slide work, and share a lot in common with the old Mesa sound you hear from someone like Carlos Santana (who has moved to Dumbles and clones himself).  Just about every modern "guitar blues" genre player has used or does use something Dumble built or inspired.  SRV, Robben Ford, Joe Bonamassa, Sonny Landreth, etc.  Honest, IMHO, the tone has become a bit of a cliche.

Plus you can have a Fender-esque clean tone.

We should note that Albert King sure didn't care if his tone was bright, harsh and ratty.  While I'm a big fan of the man's music he (as well as B.B.) often left a lot to be desired in amp tone.  Somehow he pulls it off though.
