This is a germanium/JFET booster. A unique sounding pedal which adds a beautiful sheen to your guitar’s top end and a bit of grit to the overall tone. You’ll hear a light to medium emphasis on the hi-mids and a nice round boost to the lows. It’s a fantastic pedal for situations where you want a lift in your overall level during a chorus or bridge for example with a bit of bawdy bump via the germanium transistor. One nice feature is also the more modern JFET transistor at the input which keeps the pedal impedance-friendly when it comes to other pedals and/or active pickups. This helps the Phat Phuk to remain consistent whether you put a Strat in front of it or an ESP. Another recommended use: As a simple preamp when going direct into your DAW. Helps to de-sterilize your direct tone and add a little life before hitting your favorite amp sim. Something else that was considered when creating the Phat Phuk Hybrid. Many clean-boosts offer way too much boost in my opinion. In any normal playing situation including intentionally slamming the front end of a tube amp to induce the amp’s natural overdrive one really only needs a hefty thump to get the job done. There’s nothing wrong with having a large amount of volume on tap but a problem that can sometimes occur is a lack of ability to fine tune the amount of boost you want. When the sweep of the knob goes from zero to melt-down with one turn of the knob it gets tough to really dial in a precise amount of boost. Also a slight bump of the boost knob (with a foot or nervous “live show” jitters) can send things out of control.
