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" 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®, Warwick® 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 “What is Hip” 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.

Excellent! World Class Preamp

Looking to upgrade the stock Mike Pope preamp that came with my Fodera NYC Elite.
This NYC Elite 5 string came stock with Dual Coil pickups (single/dual switch), active/passive switch, vol, tone, tre/bass

I thought long and hard about touching the electronics on this bass, but was encouraged by the reviews and capabilities of the Mike Pope 4 band EQ. And decided to pull the trigger.
Glad I did!
Took my Fodera to SF Guitarworks and had them perform the installation, and while they were at it, perform some fret work (Plek system). The difference was just strikingly amazing. First off the set-up was low, dreamy smooth and easy to play. Plugging into my rig, I felt like I just bought a new Fodera. The tone was enhanced but not colored. Taking it to a gig, I was able to dial in some great rock, slap, and Motown tones with a simple tweak of the EQ's. The 46hz bass setting is fantastic for taking on a room that is sucking up bass - what a difference. You will not be disappointed with the power the Mark Pope 4 band EQ affords you in the constantly changing live environments.
