All SAG kits are selected on a limited
basis. Please do not ask for next day or three day shipment. These
may not always be in stock. When they are ordered they will be built at
that time. This takes about two to four working days after receipt of the
order. If you order this kit with other items your other items will be
held until the kit is done. We prefer not to do partial shipments with
backorders.
Specially selected from premium Groove Tubes preamp tubes which have been
tested in our normal rigorous fashion to meet the GT standard. Special
Applications Group (SAG) provides further testing and grading for certain
performance characteristics.
This three tube set is optimized for your Fender amp which uses
12AX7 or 7025 tubes in V1 and V2.SAG-FHG includes two high gain
preamp tubes to be used in the V1 and V2 positions, and one MPI (matched phase
inverter) 12AT7 tube for the V6 position (in the case of blackface amps. The V1 and V2 tubes will increase the
front end gain structure of your amplifier as much as 20% over the typical stock
tubes you may have now. The matched phase inverter tube will assure a balanced
output section when used with matched power tubes (highly recommended) which
will assure sustain across the entire range of your
instrument.
The
MPI (Matched Phase Inverter) is a SAG Selected 12AT7 as is standard Fender
practice.
Each of the three kit tubes is marked as to it's specific rating. In
the future if you wish to change your gain structure, it is a simple matter to
request a higher or lower value as the actual characteristics of your
amplifier's gain stage is now known.
If you want a much more agressive
Fender amp; blonde, brown, black or silver face, you may want to consider the
SAG-MHG kit. These are two selected for high gain ECC83S tubes (one for V1
and one for V2) with more current output and a faster rise time than the typical
12AX7. These also have a bit more of a British flavor to some ears.
Next, the SAG-AX7-MPI in this kit, rather than the Fender used 12AT7 (in the
Fender kit this is an SAG-AT7-MPI). This will drive the output section
harder and give you more breakup faster. In essence ... a more agressive
amp. Many rock and blues players love this setup. There are no
adjustments needed. Dropping in this kit takes less than 30
seconds.
