RedPlate BlackLine/BluesLine Operations Guide
The BlackLine's Clean Preamp is designed to imitate (and surpass) all of the "classic"
blackface style guitar amp preamps by providing a full range clean tone with plenty of clear
overtones and absolute control of the midrange frequencies. The channel can be boosted from the
footswitch BOOST button and the input bass gain can be controlled via the VOICING switch on the
rear panel.
Mids Selector – A three position switch for selecting 3 variations of the midrange center
frequency, the fattest setting is in the center position.
Volume – Typical setting is between 10 and 1 o'clock but experimentation is encouraged,
engages a Bright function when pulled.
Treble Control - Adjusts highs.
Middle Control – Controls the amount of Midrange frequencies, somewhat interactive with
the Bass Control. Pulls to enable "Deep" which scoops some midrange frequencies and
emphasizes Bass (makes your electric sound more like an acoustic). For even fatter midrange
there is a Mid Boost feature enabled with a rear panel switch or via the footswitch.
Bass Control – Sets the amount of low end, somewhat interactive with the Middle Control.
The BlueLine's Clean Preamp is based on the classic Tweed Style design with some important
differences:
1. Get into the "sweet spot" and still be able to play at various volume levels and venue sizes.
2. Imitate the more traditional Treble Middle Bass style amps when needed.
3. Footswitch control of preamp Mode and Boost for instant personality changes.
4. Select the amount of Bass gain appropriate to your guitar choice (via VOICING switch on the
rear panel).
Bright Switch – Center = OFF, Down = sound of new strings, Up = normal Bright response.
Gain – Works in conjunction with the Volume to set the "sweet spot" – adjust this for the
amount of character you desire in your tone. Typical setting is between 3 and 5 but
experimentation is encouraged.
Volume – Also sets the "sweet spot" – adjust this in concert with the Gain control for the
amount of character you desire in your tone. Typical setting is between 3 and 5 but
experimentation is encouraged.
Tone – Treble is emphasized at settings past 5, more bass at the lower numbers. The tone
control is lifted via the BOOST button on the footswitch.
Mode Selector – A six position rotary switch, it steps through 6 progressively fatter positions of
midrange and girth. The fattest Tweed setting is position 6, The Tweed section can be instantly
accessed via the MID button on the footswitch.
