LaChapell Audio 500TDI 500 Series tube DI
LACHAPELL AUDIO 500TDI
500 Series Tube Direct Box (DI)
MSRP: $895

The MODEL 500TDI is a tube direct box for the 500 series format. It uses the same TrueTube™ technology that is in the popular 583S Mk2. TrueTube™ provides proper operating voltage to the 12DW7 tube so that you get rich tube harmonics and incredible detail. Two knobs allow the user to drive the tube input separate from the output for a wide array of tonal possibilities. The top input is a high impedance input while the bottom input can be used as a through OR a lower impedance input for more sound options.

SELECTED QUOTES AND REVIEWS

“I’m in total shock. I don’t know what the hell you did to get these tubes to pop like this, but it’s other Worldly. So much percussion from the note, and air around it. I can’t stop listening to it. Insane.” – Craig Young – Nashville Session Bass Player (Michael McDonald, Lady Antebellum, Faith Hill, Martina McBride)
