I agree. I did spend decent money and got a great 'halfway' solution in the Roland blues cube, but it is too closely modelled on a valve amp. I could get some great tones, but struggled to get a consistent sound from home to rehearsal to gig. I still have it because it does sound great, but rarely use it now.
I would have thought though, that Fender could use the Mustang amps as a basis for the TM series and just tweak it with decent components and speakers to make it a much better proposition with minimal cost implication, but to have it at double the cost for a 10th of the functions seems a bit steep.
So my current solution (although not gigging at the moment), is the Joyo American sound, delay and boost on a small pedal board. But, following suggestions from @Kiwi, I am now trying rack mount system to remove all the variables and just have good consistent sound from XLR into PA or small powered speaker at home. Having the no-amp situation though creates just as much stuff as you need IEM or decent monitors in order to hear yourself, so not sure how much of a better solution it really is.
