I don't recall if I have mentioned it before but a lot of my questing for dirty deeds was fulfilled whaen I got a Source Audio Aftershock and a final dimension opened up on getting the Bass Ultrawave. I know you are dubious about digital dirt and are looking for side jackers only but to me the utility of designing your own sounds with Neuro App and the extensive Neuro Cloud library make those worth reconsideration plus they are both capable of multiple functions. They pack a lot of sounds into those packages.
I think I admitted it before on this forum, but maybe not yet in this thread.
I, as a person, do not like Source Audio. I just don't. I do tolerate the C4 on my board because it bridges so many gaps for me, it's like a multi effects unit for all those effects I only use sparingly and don't have the real estate to buy a dedicated unit. With the exp pedal, I use it for volume swells and wah. I sometimes toy around with filter settings. And I get a Meatball+OC2+Mastotron+comp in one box. I can see how a drive dedicated thing with that kind of flexibility and customize options can make it for some, but for me that's a deal breaker.
I was close to getting a Chase Bliss Brothers. Then I was close to getting a Chase Bliss Preamp MkII.
I decided against both because they have too many options. I personally am completely fine with a drive pedal being a one trick pony, provided I like the one trick. Give me presets and MIDI and I'll waste hours trying for perfection for every part in every song I want to use it on.
Right now, I have more than enough:
1. Slight drive, very dynamic (Saturn)
2. Slight drive, a bit more dirty and rough (Jive)
3. Slight drive with a fat booty (Saturn into BDPG)
4. Solid drive with a rich texture and good touch sensitivity (Saturn into Jive)
5. Mayhem (all of them)
Expanding that with 128 more presets of different mixes of different drives is just ... too much.
