Amp at Every Budget
Getting the Most From Your Amp
- Use the amp's own drive channel rather than stacking too many pedals —John Petrucci's tone benefits from amp-driven saturation.
- Use reverb generously — John Petrucci's tone relies on spatial depth.
- Master volume matters — many classic tones only work at significant volume when tubes are working hard.
