There are a bunch of amps whose preamp clipping sections essentially function like built-in pedals.
. There are pedals out there costing as much and even more than a complete amp.
I know Ibanez has the TSA tube amps with a built in Tube Screamer.
It should be possible for amp makers to install the kind of pedal circuits people love ...esp for overdrive.. into the amp chassis. There are pedals out there costing as much and even more than a complete amp. Fender hot rod series are one example
Typically distortion/overdrive/fuzz are among the least expensive pedals. That is the main reason most guitar players have so many different flavors of them. However, keep in mind pedals (for the most part) try to capture the essence of an overdriven amp. For an amp to try to capture the essence of a pedal would be a bit backward, unless we are talking about modeling and that is a whole different conversation.
The least expensive ? depends. A good many sell for $ 150 to $200 ..Then there was the time when Klo Centaurs were goig for up to $3000-used. I think the Boss DS 1 is a very good pedal and quite reasonable

My Carvin Belair has a drive channel that sounds like a DS1, it's all diode clipping
My Bugera G5 has a drive stage that again sounds like diode clipping
My Laney GC80A is solid state and it drive stage is most likely diodes as well
Amp makers have been putting in overdrive pedals for the drive section for years now
It may not be the flavor you want.
but they are in there.
Peavey does this as well with their tube amps
tube distortion is a myth
Most manufacturers use pedal circuits to boost the signal to the tube already in the amp
same as the pedal guys do
