The AMP MODE Boost is a MOSFET transistor boost and is the exact same circuit found in our best-selling PRISM preamp! Ask anyone who owns a PRISM and they will likely tell you that their favorite mode on the PRISM is the AMP MODE.
Since we launched the PRISM in 2016, we have been flooded with requests to offer a standalone product based on the PRISM's AMP MODE. You asked and we listened!
AMP MODE OVERVIEW
The AMP MODE circuit is based on a MOSFET transistor, which is a very popular type of transistor for use in boost circuits because it exhibits many "amp-like" characteristics when it clips, etc. However, this circuit can have some drawbacks.
Several very popular MOSFET boost circuits on the market emit a very noticeable crackle when their boost knobs are turned. We have solved this issue in the AMP MODE so that it is perfectly silent when the boost knob is turned and delivers nothing but an incredibly loud, harmonically rich boost!
Use the AMP MODE as a preamp for your overall signal, as a boost to push an overdrive pedal even further into saturation, or as a post-overdrive boost to clarify and push your guitar forward in the mix! The AMP MODE features 9-18V operation, true bypass switching, and a small footprint with top-mounted jacks!
TONE TIP!
"One of the most powerful aspects of the AMP MODE is its ability to stack with other pedals as well as itself! For years, I used two MOSFET boosts on my pedalboard with a Klon between them. I used one of the boosts as an always-on boost, and added a second boost when I wanted a saturated rhythm sound. Finally, when I wanted a saturated lead sound, I would kick on the Klon and both boosts with the Klon gave me a super articulate, saturated lead sound." -Brad Jackson
ENHANCED CONTROL
The single boost control sets the overall boost of the AMP MODE. The AMP MODE is a true boost in that when the boost control is fully counter-clockwise, it does not amplify your signal; rather, it acts as a unity gain buffer that strengthens your guitar signal to prevent any tone loss when driving long cables, etc.
DC INPUT
The AMP MODE can safely operate from 9V to 18V DC (center negative). Running it at 18V will provide increased headroom and dynamic response. Do NOT exceed 18V!
BYPASS SWITCH
The BYPASS SWITCH is a true mechanical bypass switch.
