INTRODUCTION Congratulations on your purchase of the Revelation Tube Preamp™. The RTP is an all-tube preamplifier designed primarily for the many unique needs of the steel guitarist, but will be equally at home with bass guitar, electric guitar, acoustic guitar or just about any amplified musical instrument.
Before using your Revelation Tube Preamp, carefully read applicable items of operating instructions and safety suggestions. 1. Obey all warnings on the Revelation Tube Preamp and in The Book of Revelation Owner’s Manual. 2. Do NOT perform service operations beyond those described in The Book of Revelation Owner’s Manual.
FRONT PANEL A Instrument input Jack B Variable Impedance (Vari-Z) - This control varies the loading on the pickup or input source. Although not a true tone control, the Vari-Z will help to tailor a pickup’s tonal character. It is most noticeable on magnetic pickups.

REAR PANEL Left and Right main outputs - The upper 1/4” jacks are normal T/S (tip/sleeve) unbalanced outputs. The lower (optional) XLR jacks are true, transformer balanced outputs (pin 1 floating, pin 2 hot, pin 3 cold). The XLR outputs are made active when nothing is inserted in the corresponding ¼”...
MAKING CONNECTIONS The RTP needs to be mounted and connected properly to insure the best performance and to avoid any unwanted hums or buzzes. It is best if the RTP is mounted in a rack with the effects unit right above it. If you are also using a rack mounted tuner, it should be mounted just above the effects unit.
A bit of explanation may be useful for understanding the nature of the parallel effects loop in the Revelation Tube Preamp™. This is regarding the rear panel effects send and returns, not the front panel volume pedal loop. Many preamps use a “series” type effects loop.
Each pickup will have a sweet spot or zone that sounds best. VERY IMPORTANT: Your Revelation Tube Preamp™ is new which means that the components will need time to fully break in and sound their best. New tubes and capacitors tend to sound a bit bright when new.
