I was not 100% satisfied with what my overdrive tone in my HX Stomp. So I have being thinking about getting a separate pedal. I think my favourite that I heard lately is the Darkglass Vintage. But also the EBS Blackhaze 2 sounds really good.
However, I had an Ampeg Scrambler that I used to love before switching to the HX. And I still have it.
However, since there is an Ampeg Scrambler in the HX Stomp(when dialing my overdriven sound, I always start with it) I decided that today I was going to compare them.
My results: I think they don't sound 100% the same, but probably 95% the same. Really really close. The thing is that I saw a demo of the Darkglass and I loved the sound. Knowing the settings in that pedal, I tried to replicate it with the Scrambler pedal, and then, in the HX Stomp. And I love my tone now... Sometimes your head just says "meh, sounds too digital" until you compare it to the real thing and they sound about the same.
