The cost problem is the law of diminishing returns.
And when you play live you get to a point where the extra quality in the sound starts to get lost in the venue acoustics, and then again the average audience couldn't tell the difference anyway.
Normal its other musicians that can tell the high end product from the mid-range and that mainly in a studio.
Cheap gear is it really worth it, as you’ll get disgruntled and change it and after 3 or 4 changes you could have bought some reasonable mid-range gear in the first place.
The advantage of the gear I posted above, is
-It's lighter than guitar amp rigs.
-It's a higher output 800watt x 800watt; ok for gigs up to a 1000 or so people. (above that the main PA does that)
-I can keep my sound at any volume, at home in my bedroom, in a pub or live on stage, with no knobs needing a tweak.
-Reasonable cost. for what you get.
-versatile and instant tonal & effect setups.
It's hard to strike the quality affordability balance.
@Cringatichord (see I can dig too)
My audience can tell the difference between songs as they don’t all sound the same.
And if you’re not happy with your style and performance you don’t need another guitarists fingers, you need some LL’s DVD’s
