If you’re looking for a great preamp pedal, one of the best out there is the ZVex Super Hard On. This pedal is designed to resemble those great pedals from the 60s, right down to featuring a volume knob with a negative-feedback control that crackles when you adjust it, just like those older knobs did.
Over time, the magnets in the pickups of vintage guitars start to deteriorate. To get around this issue, the ZVex Super Hard On features a very high input impedance. It’s so high that it does not actually accept any input from the guitar, so the pickup is perfectly clear. You can actually get an output level of more than eight volts without any distortion. You can add in distortion, but it doesn’t come out as fuzz; instead, it’s a triode overload. This amp makes your guitar sound much larger and pushes your amp much harder than any other pedal, giving you a great effect. Players who complain about that strange disappearing guitar effect will find that this pedal is the perfect solution to this problem.
It’s important to note, however, that the incredibly high input impedance that the ZVex Super Hard On puts out may be a bit more than what many people expect. However, lowering the crackle okay gain knob or simply leaving the guitar volume completely open will reduce this effect. One of the other downsides of the ZVex Super Hard On is the price: it’s $239.
It's so transparent no one will be able to tell you're using a pedal. Perfect for making the most of a classic amp and guitar, because it simply makes your guitar bigger and pushes the amp harder, causing natural overload. This sound can be the solution to the 'disappearing guitar' effect you get sometimes on stage when you stomp on your distortion and sound weaker. When cranked, it sounds much louder than a fuzz or distortion under stage conditions.
