Detail 01
25/50/100-watt mode toggle
25 watts has the most compression and saturation; 50 watts balances compression and openness; 100 watts provides higher volume and open crunch with less focus.

Independent shopping perspective
JHS’s AT+ combines the original AT drive channel with a separately footswitchable boost, creating two available gain stages. Its drive circuit is unchanged from the original AT, with Volume, EQ, Drive, Air, and a three-position 25/50/100-watt mode switch. EQ sets bright-to-dark balance, while Air brings in top end for articulation and clarity. Choose 25 watts for the most compression and saturation, 50 watts for a balance of compression and openness, or 100 watts for higher volume and open crunch with less focus. The boost also runs alone into an amp or another drive pedal.
