Only spent 1 night with it, so the JP axe needs to be dialed in. With the eq, and channel two set at: master 11 presence 9, Bass 1, mid and treble at 10 or 11, and channel gain at 1:30 or two it rocks with a perfect harmonic complexity (no unwanted highs or harshness at all).Normally I would push the channel harder for the tone, but this amp seems to deliver the better tones below 11 on the channel and drive the master more. I played with the worship team last night in a hall that holds 700 people and at these setting (mic'd through the PA too) it was excellent in in no way too bright. Vary the setting by bringing up the treble and presence does immediately bring out the harshness described by others. My guess as to why there are a handful of Stiletto haters out there is due to many Mesa users are so conditioned to that nasally grind tone the rectos are known for they cannot makes this amp be a happy medium they wished it could be. It was never intended to do this.
