Lightly modified 5150. I’ve switched to modelers and just don’t need this anymore.
The Red channel is stock - it’s the high-gain grind you know and love from a 5150.
The Blue channel has the most tweaks. It’s got a bit more gain, similar to the Stealth model, but also has a switch that reconfigures the tone stack for 3 different tonal options. It can do everything from a low-gain bluesy breakup with single coils, to a full on metal assault.
The Green channel has been thickened up a bit to be warmer and generally more pleasant - but it’s still a crystal-clear clean channel.
