This preamp/direct box is so strong and powerful it could only be called the "Tone Hammer"! 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 are introducing 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.
The Tone Hammer® is the essential preamp/direct box for every bassist's tool box.

"The coolest thing about this pedal is that any one of its three features would be worth the price of the pedal by themselves. It’s a killer DI, a versatile Preamp, and a great Overdrive. It’s become a part of my rig and my sound from here on out!"
Dan Lutz - Robben Ford

"The Tone Hammer is probably the most significant thing to come out in a long time for an electric bassist. All it took was using the Tone Hammer on one gig to make me a believer - I cannot imagine not having it in my permanent live setup."
Steve Jenkins - Studio Musician

"That’s my secret weapon right there – it’s amazing. I make sure that it is always with me. It does not color your sound; it takes what it is and gives it a boost. Play through this and it is really just what your bass sounds like! I love that."
Brandon Brown - Jessica Simpson

"The TONE HAMMER is a compact way to carry a big tone; great for the studio, great for the road."
Vivi Rama - will. i. Am

"In 30 years of producing I've never been able to get a great bass sound so easily."
Steve Lillywhite - Producer (U2, Dave Matthews Band, Talking Heads)

"To me the TONE HAMMER is a lot like a cell phone. I know I used to get by without one... I'm just not really sure how. Thanks Aguilar."
Matt Noveskey - Blue October
