I just wanted to quickly chime in on my experience with the SGD 2-Band Music Man style Preamp (based on the Pre-Ernie Ball Stingray Preamp). One word - Great! I was on the hunt for an "authentic" Pre-EB 2-Band Preamp, and while there's a few choices out there, my research (and conversations with Dave, owner of SGD) lead me to check his out above the rest. My research came from this site: http://myweb.ecomplanet.com/town8019/mycustompage0019.htm Based on the photo's of true Pre-EB preamps - SGD's looks like an exact match. Board, Chip, etc... all almost identical. Photo of 1979 Stingray Preamp: Photo of SGD's 2-Band Preamp: As you can see, SGD's Preamp looks almost identical, following the same PC board design, and using the same LM4250CN chip like the original. Tone: It sounds amazing! Compared to the EBMM 3-Band the bass control is wider, fatter, and extends deeper. The treble is wider as well... and doesn't have that upper-midrange "clicky" sound. It's Overall warmer, fatter and less hyped up treble. Very "vintage" voiced and organic sounding. For more comments on tone - just research "Stingray 2-Band vs. 3-Band"... any comments you read will apply to the SGD preamp as it follows suite to both the newer Stingray Classic's, as well as the Pre-EB preamps. Construction: The definition of meticulous. All the solder joints, sleeves, etc... everything is clean & meticulous. Great "hand built" piece of gear. While I never owned a Pre-EB Stingray, I did own for a short while a Stingray "Classic" which comes with the 2-Band Preamp (which is also based on the original LM4250CN chip design). SGD's sounds identical. Props to Dave at SGD - great guy to work with and great Preamp - love it! **Also FWIW - Because I have a newer 3-Band Stingray, I had a 4th hole to fill... I decided to put a in a tone control that is also a series/parallel push-pull pot. **Note - I have the Nordstrand MM4.2 which is a 4 conductor pickup which makes this wiring possible. The price is right, and the tone is amazing. Highly recommended! For more info on SGD's preamp, click here Thanks Dave!!!!
