RedPlate Black-n-Blues Operations Guide
The Tweed Preamp is based on the classic Tweed Style design with two important differences:
1. Gets into the "sweet spot" at various volume levels for consistency of tone and character in
both small and large venue sizes.
2. Can imitate the headroom and mid scoop of more traditional Treble Middle Bass style amps
when needed.
Volume Switch – Pulls for Bright, this control sets the overall volume of the Tweed channel.
Gain – Pulls to make the Tweed channel the active channel (handy when you don't have the
footswitch connected) This control sets the "sweet spot" – adjust this for the amount of break up
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. When rotated
to zero it clicks off for a full tone lift. The tone lift can also be accessed instantly via the Boost
button on the footswitch (see the Other Features section of this manual for details).
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 Drive section controls the amount of character to add to the preamp tone. The section's
range of effect can be just a hint of early break up or a full on aggressive heavy metal distortion.
