What makes you think that blackstar is different then other brands?
How I see it: any amp, from any manufacturer, that has digital components, if one of those components goes down, odds are the only economical method for repair is replacing boards. Modeling amps, amps IR loaders, all suffer that same faith don’t they?
When you get a 100% tube amp from them….isnt it all the same across pcb amps in a certain pricerange? (Give or take a few extra bolts maybe, Idnk)
In my mind, pcb amps are a lot cheaper, and maybe have a bit of risk of higher repair costs…but they have to break first, then you need bad luck that it’s something subject to the above… before that risk materializes.
Im all for buying stuff that is likely to serve its purpose for many years to come, if not for economic reasons, then for the sake of our planet. But “risk = likelyhood * impact”, and if the price of mitigating 100% of risk is high.. sometimes accepting it is the better option.
