3 Band Tone Control

Promethean amps feature a simple 3-band tone control to adjust the tonal character.

Phat Control

The Phat control provides enhanced bottom and high end tone.

Limiter On/Off Switch

The P300H/P3110/P3115 feature an internal limiter.


The included aux input allows you to play along with a connected MP3 or CD player. The headphone out is great for bedroom jam sessions or sound checks at rehearsal.

Line Out

The XLR output sends a balanced signal to the mixing console and/or main PA system in any live or studio situation. GND Lift can cut ground loops with other connected equipment.

Tweeter On/Off Switch

The P3110/P3115 feature an on/off switch for the tweeter. This allows for even more tonal change. By turning the tweeter off, you can eliminate unnecessary high frequency overtones.
