50W built by me... mods done to mine are increased slope resistor (I think I have 56k but I'm not sure) and bass pot reduced to 250k.
I use 1x12" Celestion Gold with the amp... sometimes I add 1x12" G12-65 cab as well.
Well for me this amp is not "by the book" D sounding amp. Clean tone is very Fenderish and OD is more aggressive compared to D sound standards.
Sometime I use pedals with the amp and sometime D-lator with my Lexicon MPX1. I like both configurations... my main guitar is Tele but last gig I had, I used LP as my main axe and the amp was sounding just as good. String definition on this amp is excellent... that's why it takes pedals well I would guess.
Bass response can be challenging, so if you are after bright sounding amp than this is definitely not for you.
I would say with this amp you need to learn how to use it or you can make it sound really bad.
Definitely a good amp but not for everybody... lt's like you need to learn how to love it.
