is helpful to add gain early in the preamp with the GAIN and TREBLE set higher (5:00 & 2:00) than normal and then roll back
the PRESENCE (9:00 – 10:00) to get the sound to warm up again. This scheme can be repeated throughout all the modes and
also in reverse - where the PRESENCE is higher and the TREBLE is reduced. That said, many of the best sounds are achieved
with both TREBLE and PRESENCE straying above 12:00 noon only occasionally, as they both pack powerful frequencies that
can be dangerous at the top of their range.
Higher settings unleash the mighty roar of your Mini Recto and produce brighter, more pointed sounds that will cut through
a mix. This can be great for sparkling clean sounds in Channel 1 and more aggressive crunch rhythm sounds in PUSHED,
VINTAGE and MODERN.

MASTER

This control is the feed from the end of the pre-amp to the driver stage and the Effects Loop. As you can see,
each Channel is fitted with its own MASTER Control, enabling the two channels relative volumes to be matched regardless of

STANDBY
Perfect for set breaks...this toggle switch also serves an even more important purpose. From cold-start, the
STANDBY position allows you to warm up the tubes - especially power tubes - before applying the high voltage by switching the
Standby to the "ON" position. Before POWER is switched to "ON" - make sure the STANDBY switch is in the "STANDBY" position.
Wait at least 30 seconds and then flip the STANDBY switch to the ON position. This prevents the shock of high voltage hitting
cold tubes and reduces the likelihood of tube problems and increases their toneful life substantially.
POWER ON
This switch delivers the A.C. power to the Mini Recto. Make sure the unit is grounded (all three terminals of
the A.C. power cord must be connected to avoid injury to the user as well as to the unit) and that the proper voltage is present.
Always follow the cold start procedure described in the STANDBY section above when powering up your
amplifier. This will reduce the likelihood of tube problems and increase their musical life.

dently of the other rotary tone controls and is crucial in voicing the Modes. It is a powerful global
tone control. Lower PRESENCE Control settings darken and, in fact compress the signal, which
works well to fatten single note solo sounds, giving them girth and focus. Some of the best lead
sounds in your Recto will find the PRESENCE Control in its lower regions where a balanced, vocal
response is achieved.
One example of this would be when dialing up Bluesy solo sounds in the CLEAN Mode. Here, it
their extremely different sound styles and gain signatures. The MASTER Control makes
possible a wide range of sounds through its ability to use very low GAIN settings at high
volumes and conversely, high GAIN settings at low volumes and everywhere in between.
Again, we suggest using the MASTER Control in its sensible ranges (9:00 - 2:00). Here,
the channels will be easier to match with each other and the Effects Loop will see more
reasonable signal levels.
NOTE: Because the MASTER Control determines the send level of the Effects Loop, extreme
settings may cause possible overloading of FX processor's or pedal's Input stage, but also
may make balancing the two channels' Effect Send level difficult.
