The TR tube preamplifier is based on the motif of the preamplifier circuit of the American tube amp, the king
of clean tones, Two-Rock!
By placing it at the last stage of your effects chain and plugging it to the returns of various amplifiers, you can get a more constant “tube sound” in any studio. In addition to the return connection, simply connecting it to the input of a transistor amp also works musically. It can also be connected directly to various speaker simulator pedals.
Upgrades:
True Bypass On/Off Footswitch Option
Controls:
・GAIN: Adjusts the input gain to the preamplifier.
・3-band EQ: The effect changes seamlessly with GAIN and each mini-switch. Try different combinations.
・Bright: Adds high frequencies to the sound, and does not work when GAIN is set to maximum.
・MASTER: This adjusts the overall volume. It does not affect the tone of the preamplifier itself, so you can
reproduce the sound you created at home in the studio.
-12V DC (center-negative, 500mA or more recommended)
