Mesa Boogie 50 Caliber Low Output High Gain Option
Product Details

Want maximum gain and the earlier breakup of the JJ EL844's? This kit contains a matched quad of JJ EL844's to drop the overall output a couple decibels for the power section. Three handpicked high gain ECC83S's for V1 thru V3, a standard ECC83S for V4, and a balanced ECC83S for the phase inverter in V5. Max grind!


The Balanced ECC83S is located in V5 closest to the power tubes. The three High Gain ECC83S's are located in V1 thru V3.

Combo amps are very hard on tubes because of vibrations which can cause tube rattle with any brand of tube. If your amp is the combo version and you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings for the four EL844’s. These are available in the "Related Products” tab as a set of four and will greatly decrease tube rattle.
These amps are fixed biased, there is no bias adjustment to be made. The amount of clean headroom you’ll get from the power section is somewhat dictated by the grade of power tube used. The JJ EL844’s are a drop in replacement for EL84’s. The EL844’s will reduce the power output of the amp by a decibel or two.
