The Mojo Pad Deluxe greatly reduces feedback with any amplifier utilizing a high gain preamp design; basically, any and all guitar amps. The Mojo Pad Deluxe works by counteracting the high gain in the preamp of the amplifier by padding down the signal before it enters the amp. This allows the amplifier to achieve greater volume and opens up the tone control settings on the amp for a greater range of operation. The Mojo Pad Deluxe is bi-directional; it does not have a designated IN and OUT and it does not need power. The Mojo Pad is to be installed as the last device before your signal enters the amplifier. It has a 1 megohm input impedance, which is great for all high impedance microphones, especially those with crystal elements.
The Mojo Pad Deluxe is switchable between 20db and 10db making it a great match for any microphone and amplifier combination. The Mojo Pad Deluxe also features a Normal/Dark switch. The Normal setting allows for a balanced attenuation from low to high frequency while the Dark setting lightly trims the high fequencies more than the low frequencies.
Remember the Mojo Pad Deluxe is intended for amplifiers with high gain preamps; these amplifiers typically have 12AX7 tubes at the input. The Mojo PadDeluxe also works with any solid state amp. With the Mojo Pad, there is no need for tube swapping.
The Mojo Pad Deluxe is not recommended for harmonica specific amplifiers, meaning amplifiers built for use with harmonica and microphone or amplifiers whose preamp tubes have been replaced with low gain preamp tubes.
