Altec 1567 Mod: This Mod came about at the request of some customers who noted the fantastic sonic characteristics of the Altec 1567 Mixer due to good sounding tubed mic pres, but found some significant drawbacks that prevented the practical use of the unit in music production. The Drawbacks :The EQ, when not needed, still added noticable hiss to the output.
This unit has a mono output, and it’s unusual to be summing 4 mics in modern music production. Most Altec 1567 owners are only using the unit for amplification of one, or at most two mics. Yet s..
Ampex 350 Mic Pre Optimizaton Mod: This mod turns a somewhat unusable Ampex 350 electronics channel into one of the most impressive mic pres ever! Capitalizing on a fantastic design by the brilliant Ampex engineers this mod eliminates drawbacks to practical use in the recording of music while preserving and even teasing out a bit more of the inherent impressive sound. The result is totally usable hot neon like sound that is unmatched by other mic pres, a close second perhaps being the Neumann V76. This modified mic pre has all-around utility: it is thunderously punchy, has a w..
Ampex 601 Mic Pre Optimizaton Mod: This mod turns a somewhat unusable Ampex 601 electronics channel into a damn good mic pre, in the way of a oddly well working old car that has some bonafide character. While it’s not the Everest of Mic Pres, when well modified, it’s one that you will be happy to own and probably never sell. It’s hard to describe mic pre character with written word, but one thing is easy enough to be said of this mic pre, namely it is warm sounding and there’s nothing thin about it. ‘The Drawbacks :Mos..
Ampex MX-35 Mic Pre Mixer Mod: The Ampex MX-35 is a fine little mixer from the late tube era. The circuitry is straight forward Class A (as are most tube circuits) resulting in an overall smooth, clean sound. The microphone input transformer is interesting in that it is very small...sometimes referred to as a “thumb” transformer. Usually a small transformer lacks low end response, as theory says it will saturate easily and thus attenuate peaks of low frequency signal. Somehow the thumb transformer in the MX-35 is able to pass low frequencies with minima..
Gates SA 39 mod: This mod turns a somewhat unusable Gates SA39 limiter into one of the most impressive limiters ever! Capitalizing on a fantastic design by the brilliant Gates engineers this mod eliminates drawbacks to practical use in the recording of music while preserving and even teasing out a bit more of the inherent impressive sound. The result is a totally usable fat, warm and punchy sound equal to but not surpassed by just a few other similar units. It does improve the sound passing through it. It calls attention to the instrument or vocal being recorded.&n..
