RedPlate BlackVerb Jr Operations Guide

Welcome to the RedPlate Family, thank you for your purchase of a RedPlate BlackVerb Jr

amplifier. Please take a moment and review this manual for an understanding of all the

available features (or just put all the knobs at noon and play).

This Manual applies to BlackVerb Jr models produced after 011/01/2013.

FRONT PANEL:

Input Jack – Typical High impedance input to the amplifier. Designed to be "Pedal Friendly" for

use with all your favorite pedal choices.

The Clean Preamp is designed to imitate (and surpass) all of the "classic" guitar amp preamps.

The BlackVerb Jr preamp gives the player the ability to do two unique things:

1. Shift the midrange center point frequency.

2. Do a full tone stack lift. (See Bass Control description).

Bright Switch – Center = OFF, Down = sound of new strings, Up = normal Bright response.

Volume – Typical setting is between 3 and 5 but experimentation is encouraged

Treble Control - Adjusts highs (also upper midrange when the Mode Switch is rotated to

position 6).

Middle Control – Controls the amount of Midrange frequencies, somewhat interactive with

the Bass Control.

Mode Selector – A six position rotary switch, it steps through 5 progressively fatter positions of the midrange center frequency and achieves maximum fat midrange by engaging a MidRange Boost in position 6.
Page 3 MAINTENANCE SECTION Your BlackVerb Jr amp has been designed for years of trouble free operation. The vacuum tubes will need to be replaced over time. We recommend new output tubes every 160 - 240 hours and new preamp tubes every 320 - 480 hours.
Page 4 INTERNAL TRIM POT The BlackVerb Jr has an internal trim pot for PI Balance – Useful for working with unmatched 12AX7 tubes in the phase inverter position. Refer to qualified personnel for proper setting.
