MPC 5 - Power Overdrive

Electra Catalog Description

30% volume increase with the flick of a switch.  Lets you change from mild rhythm or soft lead to pure power leads with rich harmonic overtones.

MPC 05 Module

Above is a stock MPC 05 Power Overdrive module.  Below are it's insides.

John Thornburg is offering a modification for the Power Overdrive module that I feel is really worthwhile.   I recently picked up a modified MPC05 from John, and I love it!  It has quite a bit more bite than the stock MPC05 in my opinion.  I would liken John's modified module to be very much like the vintage Electro Harmonix LPB-1's I used to use in the 70's.  Let's face it, the stock MPC05 Power Overdrive is an ok overdrive unit, but John's modification makes it a great overdrive unit.  For more info, email him directly at jthornburg@sigecom.net .

 

Review by Mike C

Most MPC models came with two standard modules, the Phase Shifter and Power Overdrive. The Overdrive module provides some additional volume and sustain. It is not as easily recognizable as say a Phaser, but it can help if you are playing against stronger amps or other equipment, or if you just want more sustain.


Review by Webmaster

The Power Overdrive reminds me of an icon from the 70's, the Electro Harmonix LPB-1.  I loved the LPB-1 and I love the Power Overdrive.  At the flick of the switch you can overdrive your tube amp just a little bit more for some smooth distortion or a little extra volume if needed.  Simple, but very useful.  I highly recommend John Thornburgs mod to the MPC05, the improvement is amazing!


Review by Steve H

I find this module to have neither power nor overdrive. The concept, as I understand it, was to provide clean boost that you could use to overdrive an amp, or boost a solo. The problem is that there just isn't much gain there. And there's often quite a bit of noise. I know another MPC fan who has spent hours taking apart MPC5 modules and attempting to modify them. He eventually came up with a nice mod that gives much more gain, and yet keeps the tone beefy. Nice. Drop me an email and I'll put you in contact with him. I've actually found some documentation that suggests that there was two distinct versions of MPC5. The simple version looks like the schematic linked on the MPC4 review page, except without the diodes on the output. It is built using the MPC3 Treble/Bass Expander circuit board, with different components in a modified layout. As a matter of fact, it is the exact same circuit as the Dynamic Fuzz, leaving out a couple of diodes. They certainly were keeping an eye on costs over there at SLM. There is a different version using two transistors, also. I believe this to be the most common one.
