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 rear panel control aptly named "PUSSY
TRIMMER". 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.
Can I substitute different tube types for the 12AX7/ECC83s or 6V6s?
- 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 is not
recommended for the Son of Yeti 20W.
What settings do you recommend?
