Oh wow. I don't think there is any single pedal that can do the job. As You noticed and chose to go with Boss Ls2 etc.
Many boutique builders do relatively cheap custom jobs, that's the idea: You pay extra for them for giving You a good ear and they do their best to achieve Your totally lifeless synth with clean blend for transparent and uneffected sound. Sure it's probably not under 150$ but then again - it can be perhaps exactly what You're looking for AND if it's not, You've already learned much about what You want, what You don't want, what certain fx can achieve and You go on from there. It's a process. It takes time. Don't expect a ready made Acme-just-add-water solution. Ask anybody, these things take time and experimentation. As you should know
But chill out. Please. Or leave if it's too much asked to be civil and play by the unwritten code of conduct of the fuzz head weirdos brotherhood. Or burst like a fucking volcano and THEN say chill out and say sorry dudes.

Good advices in an Internet forum thread come with patience and conversation. As with conversation with builders.
Ta-ta.
Soon I call for a group of nazis on thin ice doing the hammer time routine shuffle dance.
