"Control Configuration  Volume Active/Passive Push/Pull Volume Passive Tone Treble Lo Mid/Hi Mid Stack Bass The Mike Pope Flexcore is a 1 to 4-band preamp that is an extremely nimble and flexible preamp system capable of allowing the user to choose what control layout fits best for their bass. Originally found on high end boutique builds from Fodera these preamps are now available for use in whatever bass you the player sees fit. These preamps require a minumum control cavity depth of 1 1/4&amp;quot; and are intended for use with basses already equipped with a rear control route. They can be used with either Active pickups such as EMG&amp;amp;reg;, Warwick&amp;amp;reg; MEC, and passive pickups such as Bartolini, Nordstrand, Delano, Aguilar, and Seymour Duncan as well. Tonally the preamps are clean, clear, and very transparent. The circuitry in the MPP preamps is designed to help, not harm. When you set the tone shaping controls flat there is no coloration or contour of the pickup's signal. Once installed the player can dial in tones anywhere from the up front in your face slap tones to a darker &amp;amp;ldquo;What is Hip&amp;amp;rdquo; finger style tones, and deep and hollow rock tones to an aggressive, Rickenbacker style edge. The circuit is there to help you without interjecting it's own personality. It's there to serve your needs. Install is very simple and fully modular. Inputs for pickup connection, and grounds for instance is handled onboard with screw terminals as opposed to requiring soldering like other preamps. The pot shafts are solid and can use knobs with set screws for install.Standard single potentiometer's require a single 6mm knob for use, and any concentric stack will require an 8mm lower, 6mm upper knob for use. The preamp has provisions for 2 different frequency centers for each of its bass, lo-mid, hi-mid and treble controls with the bass and treble control selectable via included jumpers in the cavity and the mid frequencies selectable via jumpers or optional switches.
