I rely on the amp block for the majority of the sound, just as I do with my real amps. I don’t subscribe to the idea that the amp should be crystal clear and only provides volume and the pedals provide all the dirt and distortion. Before we had pedals we relied on the amp for volume and the distortion was a necessary evil because we couldn’t get the volume we wanted. Then we grew to associate that distortion with rock and roll, jazz, and country and it became a mainstay of the sound of the amps and every decent amp had to have a decent amount of distortion when rolled up.
Pedal makers initially wanted to augment that distortion, then, as amps got louder and people started turning down their amps, the makers began trying to reproduce the sound of the amps’ distortion because a big amp turned down lost that sound. At some point younger players assumed that’s how it should be, maybe because cheaper amps couldn’t get that sound, but the rigs shifted to clean amps with no defining character in their sound and big pedalboards with multiple distortion and dirt and overdrive pedals. (Perhaps it was because pedals are usually cheaper than the amps and the players didn’t know what to listen to in the sound to tell if it was a realistic reproduction of the distorting amp.) Whatever the cause, there was a shift.
Boutique amps, the real ones, not the ones that have “boutique” simply slapped on them by their marketing people, came about to reproduce the old style amp sound from the tubes, and then go beyond what the original circuits did. Being able to reliably reproduce the tube sound at lower volume was what got me to try, then buy, my first boutique … well, that and my tech who told me that trying to get a Fender to sound like a Tone King Imperial Mk II wasn’t going to happen and I needed to buy the Imperial. Having a 20 watt amp that can scream like an old JTM-45 Marshall on 10 is… invigorating… so I use my amp block just like my amp, it’s 99% of the sound and a pedal is just to occasionally push the sound a little harder or a different way.
And, even though I can imitate a full pedalboard with esoteric effects into a crystal clear amp that can switch to a screaming monster by stepping on a switch, I still prefer to crank the amp to 11 and rely on my guitar’s volume control to go from clean to full distortion. Perhaps one of these days I’ll wake up and quit putting a “clean” scene in my presets, because I never use them.
