Brand New with Warranty​​​​​​​. We are an authorized Aguilar dealer.

Based on the respected OBP-3 preamp, the Tone Hammer® features fully sweepable midrange frequencies in addition to bass and treble controls. With the Tone Hammer’s pristine D.I. you are set for the studio or the stage. To give this tone shaping unit the ultimate flexibility we introduce our proprietary Adaptive Gain Shaping circuitry (AGS). AGS allows the player to kick in an additional gain structure and EQ with the “stomp” of a button. You can now go from modern slap sounds to vintage or overdriven. 18 volt operation gives the Tone Hammer® plenty of headroom to reproduce the most dynamic playing style. Separate GAIN and MASTER controls allow you to dial in just the right gain structure for any instrument.

What we think:

  • Powerful EQ with sweepable midrange
  • Sends pristine DI tones to a live or recording console
  • Looking for more colored, amp-like tones? Engage the AGS
  • Push the Gain to dish out some serious dirt
  • AGS is interactive with Gain control, so you can also dial in a perfect solo “boost”
  • Capable of giving an “active” bass personality to your favorite passive bass
