This is "Satisfaction" period!

I just plugged it in for a couple minutes, because it's horribly late, but I will no longer have to build the Maestro. The Tone Bender Mark II Professional NPN Germanium version from G. G. G. IS that tone! It absolutely nails that tone to the wall. Marty Mart turned me on to the OC140 NPNs, so I bought several. They are absolutely awesome, new old stock Ministry of Defense, NPN germaniums. My Si tone Bender is also wonderful in it's own way, but different in tone. This one has that 60s tone you've been looking for, if you want the Maestro Satisfaction tone. With what little bit I have messed with it now, the "Attack" pot, can only be at about the half way point, or it makes the effect turn gatey. I don't know if it has something to do with the bias, but it sure seems so. It has a very heavy buzzy fuzz, but still not as aggressive as the Shin-ei I built a few hours before it. Both are wonderful! I am thrashed, and it's time for bed. I guess a lot of people might travel on their vacation. I decided to build Classic Effects. Man, it's a sickness!

It's got killer tone with the Attack pot only half way up? What guitar/amp are you running it through?

After trying unsuccesfully to build the Fuzz-Tone I easily built Escobedo's Lofo Mofo and got the 2,000 Pound Bee tone I was after. Much simpler.

Oh Oh ..... "Fuzz Sickness"  !
watch out with that, it causes your "wallet" to become very "light" !!   
MKII Pro, yup that is quite a "killer tone"  nice

Where can we source these OC140 NPNs?

The MKII Pro is quite the fuzz, a nice alternative to the standard Dallas Fuzz. Cuts thru nicely with single coils. I'm amazed it sounded so "heavy" and "buzzy" being misbiased, and with the Attack pot (1k lin.) only half way up.
