The AMP MODE Boost is a MOSFET transistor boost and is the exact same circuit that is found in our best selling PRISM Preamp! Ask anyone who owns a PRISM and they'll most likely tell you that their favorite mode of the PRISM is the AMP MODE.
 
AMP MODE OVERVIEW
The AMP MODE circuit is based on a MOSFET transistor which is a very popular type of transistor to use for boost circuits because it has many “amp like” characteristics when it clips etc. There can be downsides to this circuit though.
 
Several very popular MOSFET boost circuits on the market have a very noticeable crackle when their boost knobs are rotated. We fixed this issue in the AMP MODE so it is perfectly silent when the boost knob is rotated and delivers nothing but a crushingly loud and harmonically rich boost!
 
Use the AMP MODE as a preamp for your overall signal, 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 tiny footprint featuring top mounted jacks!
 
BOOST CONTROL
The single boost control sets the overall boost for the AMP MODE. The AMP MODE is a true boost in that when the boost control is fully counter-clockwise, it doesn't boost your signal, it instead acts as a unity gain buffer that emboldens your guitars signal to prevent against tonal loss when drive long cables etc.
 
DC INPUT
The AMP MODE can safely run from 9V-18V DC (center negative). Running it at 18V will give increased headroom and dynamic response. Do NOT exceed 18V!
 
BYPASS SWITCH
The BYPASS SWITCH is a mechanical true bypass switch.
