The MMSR 4 Knob 3 Band has been designed with characteristics very similar to the original MM Stingray© 2 Band EQ, in order to retain the same interaction between the MM pickup and the electronics, crucial in creating the original pre EB sound colours. A Mid Sweep, is included along with original MM style Bass and Treble. When the Mid boost/cut is centred, its effect is neutral and the EQ is purely late 70s MM style.

The MMSR 4 Knob 3 Band has been designed with characteristics very similar to the original MM Stingray© 2 Band EQ, in order to retain the same interaction between the MM pickup and the electronics, crucial in creating the original pre EB sound colours. Our circuit additionally has separate stages for the bass and treble, allowing us to further enhance and extend the bass control. A Mid Sweep, is included along with original MM style Bass and Treble. When the Mid boost/cut is centred, its effect is neutral and the EQ is purely late 70s MM style.

Control Knobs & functions:

Single Knob - VOLUME
Single Knob - Late 70s MM style TREBLE
Stack Knob - MID / MID FREQUENCY SWEEP (Mid Sweep 01)
Single Knob - Late 70s MM style with enhanced BASS

This unit is supplied fully wired with 3 single and 1 stacked pot including knobs, Switchcraft jack plus battery clip, which may be spliced into an existing battery box, as would be available in most MM style basses. There are screw terminals for the pickup connections for easy installation and a ground wire is provided to connect the bridge and any other grounding points/screening. Out of the box, just connect the pickup, snap on a battery, plug into a rig and you have sound, but remember that the grounding connections are crucial in attaining a solid installation.

The MMSR 3 Band can be supplied with or without a plate, but our plates will fit only SUBs and OLP basses. It will be necessary to use the existing plate on a standard MM bass.

NOTE: The MMSR 4 Knob 3 Band without plate, is suitable for the MM Sabre© too, the later type where the jack is on the side of the bass. Connection for a bright toggle are included.

What they say!

* Dear John I am writing to thank you for the excellent MMSR preamp that you made for me. My Stingray was my main bass for ten years until I purchased a Sadowsky Jazz in 2008. The Stingray bass could not compete with the powerful plug in and go tone and with the flexibility of the Sadowsky sound. It irritated me that my ‘first choice’ Stingray bass found itself pretty redundant. I discovered the MMSR on your website about 18 months ago but was hesitant because I could never be certain it would solve my problem and I did not want to change the appearance of the bass (with the stacked mid control) or remove its ‘Stingray sound’. I was immediately impressed with the appearance of the MMSR circuitry when I took it out of the box. The installation was very straightforward and the near solder-less installation is genius. After plugging in the upgraded bass for the first time I was truly stunned by result. My Stingray sounded like a Stingray but with greater clarity and less hiss. The bass and treble controls intuitively flavour the tone without muddying the sound. I am also totally sold on the stacked mid control. I compare its purpose to the pickup blend on the Sadowsky Jazz and as a consequence I now have two basses of fundamentally different character but equal flexibility and extreme high quality. So… many thanks indeed! Paul - UK

* Hi John, used the bass on Thursday night and it sounded great, the bottom end was far more solid and powerful, the top end had some sizzle which it never had before. The mids are the icing on the cake and they make the bass far more flexible than it was before. A success I'd say :) Thank you so much, I'm much happier about this bass now. Speak soon. Mike - UK

* Hello John, I received the MMSR preamp yesterday and installed it right away. It lives up to its reputation. I've never owned a pre-Ernie Ball MM bass but I am familiar with the sound and your pre-amp gets me closer to it. The rest is down to the strings and the amp. The stock preamp seemed to emphasize fret noise all the time, unless I wanted no treble at all. Your pre-amp has many more useful tones, even without the sweeping mid. Thank you very much, John. I will be playing this bass more often now! Paul - Canada
