User manual FENDER PX 2208D

[. . . ] There are no solid-state (transistor) devices in the signal path of any kind. This amplifier was created from the efforts of a handful of top craftsmen, players and designers who saw a need and envisioned a new amplifier. Like the other Fender custom amps, the new Dual Professional is painstakingly built, one at a time, by a select group of craftsmen at the Fender electronics factory in Lake Oswego, Oregon. [. . . ] It is equipped with the 3-knob tube reverb for maximum versatility of reverb effects. The vibrato effect in the Dual Professional is of the direct-coupled oscillator type not heard from since the early 60s, giving a much different effect than the "Blackface" type tremolo, as found in the Twin Reverb®. It has 2 volume controls, switchable via the front panel CHANNEL A/B switch or the footswitch. There is also a corresponding FAT switch for each volume control, so that two separate sounds may be preset and selected during performance. The speakers in the Dual Professional are CELESTION® Vintage 30s, selected for their clear, powerful tone. The 2 button footswitch provided will switch the vibrato on or off as well as toggle between the VOLUME A/ FAT A and VOLUME B/ FAT B controls. It is suggested that you read this manual thoroughly to understand all the features and functions of this amplifier. This amplifier will provide years of trouble-free service and playing enjoyment. PX 2208D FRONT PANEL FUNCTIONS A. Input 2 will work as a 6dB lower gain, low-Z input for hot, active pickups or as a passive output to link amplifiers in a multiamp set up. It may be used as a reinsertion point in an effects loop, or as a guitar input when no reverb is desired. H. EFFECTS SEND - This sends the instrument signal from INPUTS 1 and 2 along with the reverb out of the amplifier at a -20 dB level. It may be used to drive effects units in an effects loop, or it may be used to drive additional amplifiers in a multi-amp set up. VIB - Push on, push off switch that turns the VIBRATO feature on and off. CHA - Push on, push off switch that turns the CHANNEL A/B feature on and off. K. LINE CORD - (not shown) Your amplifier is equipped with a 3-prong grounding type supply cord to reduce the possibility of shock hazzard. WARNING: THIS EQUIPMENT MUST BE EARTH GROUNDED. TUBES The Dual Professional tube complement consists of 4 Fender special design 5881/6L6WGC's (part# 039214), 5 Fender special design 12AX7WA's (part#013341), and 1 Fender special design 6V6GTA (part# 023564). Fender's special design tubes provide optimum performance in this amplifier. Tube life varies with playing style and application, but for best tone, tubes should be changed after every 500 hours of use.
