Ruff Records EzTubeMixer

Projects > Ruff Records EzTubeMixer

Born out of Ian Thompson-Bell’s “Poor Man’s Tube Preamp” design, is a fully functional tube mixer project with provisions for 60dB preamps, hi-impedance DI inputs, passive EQ (Pultec, Helios, or REDD-style), faders, and up to 4 mix busses. The design is modular and open in its implementation, allowing builders to come up with a console that fits their needs. Although the project is not recommended for beginners due to its magnitude (as well as its basis in tube operation), it is a fairly inexpensive project when compared alongside the typical cost of purchasing an all-tube console.
