Sometimes when I play with both BRIGHT switches engaged, the amp wants to feedback/squeal. Is this normal?
- For an amp with this much gain and lack of treble roll off, yes. We've carefully tuned the resonant frequency
of the amp to exemplify the sound of the hot-rodded Plexis of yore. A byproduct of this voicing is the
tendency to feedback if both BRIGHT controls are engaged, which dramatically boosts the upper-mid and
high frequency content.
- If this is an issue, you can simply turn off BRIGHT 2, or decrease gain settings, or turn down your guitar
volume during breaks. If you need all of that gain, and then some, we recommend a noise gate (standard
procedure on any modern high-gain amplifier).
- However, if you are a straight-to-amp player, we have installed a trimmer aptly named "PUSSY TRIMMER".
The amp is sent from our test bench with it at its maximum setting (out of circuit). If this background gain
wash and tendency to feedback bothers you, you can turn down this control to reign in the amplifier's
"gainiac" nature. The PUSSY TRIMMER is currently offered on the rear panel.
Can I substitute different tube types for the 12AX7/ECC83s or 6L6GCs?
- Although you can try 12AT7s, 12AU7s, 5751s without any harm, the design is optimized for 12AX7s, and are
therefore the only recommended tube in the preamp positions. Usage of other power tubes (ex – 6550s,
6L6GCs, modern 6V6s like Electro-Harmonix, JJ) may be possible, but please first consult Ceriatone
Amplification or your local competent amplifier technician.
What settings do you recommend?
