I guess it goes both ways... Sometimes yes, sometimes no. I've had inexpensive gear that I've dumped as it didn't do the trick. I've got some other inexpensive gear that's awesome, and it's stuck around... Case in point, I've had a Peavey Classic 30 now for about 15 or 18 years...not sure, doesn't matter. Thing ALWAYS sounded amazing for the cleans to overdriven cleans, the dirt channel sucked though. ANYWAY, since then I've installed a Celestion Gold Alnico, decent glass and some changes to the circuit and components...this little "cheap" tube amp has got some of the sweetest clean tones I've ever heard from any amp!!! Turn it up till it starts to break up?? The Alnico Gold is pure buttah!! Stick a Mk.4:23 in front of it?? I don't care who you are, it's some of the finest boutique amp tone I've ever heard, both Lester and single coil love... It's my go-to clean amp.
So it goes...
Peace,
